Version 1.11.1
--------------
* hwloc-annotate does not drop unavailable resources from the output anymore
and those may be annotated as well.
* Fix an overzealous assertion when intermediate Group object while Groups
are totally ignored.
* Fix a memory leak on failure to load a xml diff file.
* Fix some segfaults when inputting an invalid synthetic description.
Version 1.11.0
--------------

+ Socket objects are renamed into Package to align with the terminology
used by processor vendors. The old HWLOC_OBJ_SOCKET type and "Socket"
name are still supported for backward compatibility.
+ HWLOC_OBJ_NODE is replaced with HWLOC_OBJ_NUMANODE for clarification.
HWLOC_OBJ_NODE is still supported for backward compatibility.
"Node" and "NUMANode" strings are supported as in earlier releases.
* Detection improvements

- Collapse identical PCI devices unless --no-collapse is given.
This avoids gigantic outputs when a PCI device contains dozens of
identical virtual functions.
- The ASCII art output is now called "ascii", for instance in
"lstopo -.ascii".
The former "txt" extension is retained for backward compatibility.
- Automatically scales graphical box width to the inner text in Cairo,
ASCII and Windows outputs.
- Add --rect to lstopo to force rectangular layout even for NUMA nodes.

- Objects may have a "Type" info attribute to specify a better type name
and display it in lstopo.
- Really export all verbose information to the given output file.
+ hwloc-annotate
- May now operate on all types of objects, including I/O.
- May now insert Misc objects in the topology.
- Do not drop instruction caches and I/O devices from the output anymore.

on some node, it should use HWLOC_MEMBIND_BIND.
Thanks to Nicolas Bouzat for reporting the issue.
+ Add a "Miscellaneous objects" section in the documentation.
+ Add a FAQ entry "What happens to my topology if I disable symmetric
multithreading, hyper-threading, etc. ?" to the documentation.
Version 1.10.1
--------------
* Actually remove disallowed NUMA nodes from nodesets when the whole-system
flag isn't enabled.
* Fix the gathering of PCI domains. Thanks to James Custer for reporting
the issue and providing a patch.
* Fix the merging of identical parent and child in presence of Misc objects.
Thanks to Dave Love for reporting the issue.
* Fix some misordering of children when merging with ignore_keep_structure()
in partially allowed topologies.
* Fix an overzealous assertion in the debug code when running on a single-PU
host with I/O. Thanks to Thomas Van Doren for reporting the issue.
* Don't forget to setup NUMA node object nodesets in x86 backend (for BSDs)
and OSF/Tru64 backend.
* Fix cpuid-x86 build error with gcc -O3 on x86-32. Thanks to Thomas Van Doren
for reporting the issue.
* Fix support for future very large caches in the x86 backend.
* Fix vendor/device names for SR-IOV PCI devices on Linux.
* Fix an unlikely crash in case of buggy hierarchical distance matrix.

Erik Schnetter for helping debugging.
* Fix hwloc_bitmap_isincluded() in case of infinite sets.
* Change hwloc-ls.desktop into a lstopo.desktop and only install it if
lstopo is built with Cairo/X11 support. It cannot work with a non-graphical
lstopo or hwloc-ls.
* Add support for the renaming of Socket into Package in future releases.
* Add support for the replacement of HWLOC_OBJ_NODE with HWLOC_OBJ_NUMANODE
in future releases.
* Clarify the documentation of distance matrices in hwloc.h and in the manpage
of the hwloc-distances. Thanks to Dave Love for the suggestion.
* Improve some error messages by displaying more information about the
hwloc library in use.
* Document how to deal with the ABI break when upgrading to the upcoming 2.0
See "How do I handle ABI breaks and API upgrades ?" in the FAQ.
Version 1.10.0
--------------
* API
+ Add hwloc_topology_export_synthetic() to export a topology to a
synthetic string without using lstopo. See the Synthetic topologies
section in the documentation.
+ Add hwloc_topology_set/get_userdata() to let the application save
a private pointer in the topology whenever it needs a way to find
its own object corresponding to a topology.
+ Add hwloc_get_numanode_obj_by_os_index() and document that this function
as well as hwloc_get_pu_obj_by_os_index() are good at converting
nodesets and cpusets into objects.
+ hwloc_distrib() does not ignore any objects anymore when there are
too many of them. They get merged with others instead.
Thanks to Tim Creech for reporting the issue.
* Tools
+ hwloc-bind --get <command-line> now executes the command after displaying
the binding instead of ignoring the command entirely.
Thanks to John Donners for the suggestion.
+ Clarify that memory sizes shown in lstopo are local by default
unless specified (total memory added in the root object).
* Synthetic topologies
+ Synthetic topology descriptions may now specify attributes such as
memory sizes and OS indexes. See the Synthetic topologies section
in the documentation.
+ lstopo now exports in this fully-detailed format by default.
The new option --export-synthetic-flags may be used to revert
back the old format.
* Documentation
+ Add the doc/examples/ subdirectory with several real-life examples,
including the already existing hwloc-hello.C for basics.
Thanks to Rob Aulwes for the suggestion.
+ Improve the documentation of CPU and memory binding in the API.
+ Add a FAQ entry about operating system errors, especially on AMD
platforms with buggy cache information.
+ Add a FAQ entry about loading many topologies in a single program.
* Misc
+ Work around buggy Linux kernels reporting 2 sockets instead
1 socket with 2 NUMA nodes for each Xeon E5 v3 (Haswell) processor.
+ pciutils/libpci support is now removed since libpciaccess works
well and there's also a Linux-specific PCI backend. For the record,
pciutils was GPL and therefore disabled by default since v1.6.2.
+ Add --disable-cpuid configure flag to work around buggy processor
simulators reporting invalid CPUID information.
Thanks for Andrew Friedley for reporting the issue.
+ Fix a racy use of libltdl when manipulating multiple topologies in
different threads.
Thanks to Andra Hugo for reporting the issue and testing patches.
+ Fix some build failures in private/misc.h.
Thanks to Pavan Balaji and Ralph Castain for the reports.
+ Fix failures to detect X11/Xutil.h on some Solaris platforms.
Thanks to Siegmar Gross for reporting the failure.
+ The plugin ABI has changed, this release will not load plugins
built against previous hwloc releases.
Version 1.9.1
-------------
* Fix a crash when the PCI locality is invalid. Attach to the root object
instead. Thanks to Nicolas Denoyelle for reporting the issue.
* Fix -f in lstopo manpage. Thanks to Jirka Hladky for reporting the issue.
* Fix hwloc_obj_type_sscanf() and others when strncasecmp() is not properly
available. Thanks to Nick Papior Andersen for reporting the problem.
* Mark Linux file descriptors as close-on-exec to avoid leaks on exec.
* Fix some minor memory leaks.
Version 1.9.0
-------------
* API
+ Add hwloc_obj_type_sscanf() to extend hwloc_obj_type_of_string() with
type-specific attributes such as Cache/Group depth and Cache type.
hwloc_obj_type_of_string() is moved to hwloc/deprecated.h.
+ Add hwloc_linux_get_tid_last_cpu_location() for retrieving the
last CPU where a Linux thread given by TID ran.
+ Add hwloc_distrib() to extend the old hwloc_distribute[v]() functions.
hwloc_distribute[v]() is moved to hwloc/deprecated.h.
+ Don't mix total and local memory when displaying verbose object attributes
with hwloc_obj_attr_snprintf() or in lstopo.
* Backends
+ Add CPUVendor, CPUModelNumber and CPUFamilyNumber info attributes for
x86, ia64 and Xeon Phi sockets on Linux, to extend the x86-specific
support added in v1.8.1. Requested by Ralph Castain.
+ Add many CPU- and Platform-related info attributes on ARM and POWER
platforms, in the Machine and Socket objects.
+ Add CUDA info attributes describing the number of multiprocessors and
cores and the size of the global, shared and L2 cache memories in CUDA
OS devices.
+ Add OpenCL info attributes describing the number of compute units and
the global memory size in OpenCL OS devices.
+ The synthetic backend now accepts extended types such as L2Cache, L1i or
Group3. lstopo also exports synthetic strings using these extended types.
* Tools
+ lstopo
- Do not overwrite output files by default anymore.
Pass -f or --force to enforce it.
- Display OpenCL, CUDA and Xeon Phi numbers of cores and memory sizes
in the graphical output.
- Fix export to stdout when specifying a Cairo-based output type
with --of.
+ hwloc-ps
- Add -e or --get-last-cpu-location to report where processes/threads
run instead of where they are bound.
- Report locations as likely-more-useful objects such as Cores or Sockets
instead of Caches when possible.
+ hwloc-bind
- Fix failure on Windows when not using --pid.
- Add -e as a synonym to --get-last-cpu-location.
+ hwloc-distrib
- Add --reverse to distribute using last objects first and singlify
into last bits first. Thanks to Jirka Hladky for the suggestion.
+ hwloc-info
- Report unified caches when looking for data or instruction cache
ancestor objects.
* Misc
+ Add experimental Visual Studio support under contrib/windows.
Thanks to Eloi Gaudry for his help and for providing the first draft.
+ Fix some overzealous assertions and warnings about the ordering of
objects on a level with respect to cpusets. The ordering is only
guaranteed for complete cpusets (based on the first bit in sets).
+ Fix some memory leaks when importing xml diffs and when exporting a
"too complex" entry.
Version 1.8.1
-------------
* Fix the cpuid code on Windows 64bits so that the x86 backend gets
enabled as expected and can populate CPU information.
Thanks to Robin Scher for reporting the problem.
* Add CPUVendor/CPUModelNumber/CPUFamilyNumber attributes when running
on x86 architecture. Thanks to Ralph Castain for the suggestion.
* Work around buggy BIOS reporting duplicate NUMA nodes on Linux.
Thanks to Jeff Becker for reporting the problem and testing the patch.
* Add a name to the lstopo graphical window. Thanks to Michael Prokop
for reporting the issue.
Version 1.8.0
-------------
* New components
+ Add the "linuxpci" component that always works on Linux even when
libpciaccess and libpci aren't available (and even with a modified
file-system root). By default the old "pci" component runs first
because "linuxpci" lacks device names (obj->name is always NULL).
* API
+ Add the topology difference API in hwloc/diff.h for manipulating
many similar topologies.
+ Add hwloc_topology_dup() for duplicating an entire topology.
+ hwloc.h and hwloc/helper.h have been reorganized to clarify the
documentation sections. The actual inline code has moved out of hwloc.h
into the new hwloc/inlines.h.
+ Deprecated functions are now in hwloc/deprecated.h, and not in the
official documentation anymore.
* Tools
+ Add hwloc-diff and hwloc-patch tools together with the new diff API.
+ Add hwloc-compress-dir to (de)compress an entire directory of XML files
using hwloc-diff and hwloc-patch.
+ Object colors in the graphical output of lstopo may be changed by adding
a "lstopoStyle" info attribute. See CUSTOM COLORS in the lstopo(1) manpage
for details. Thanks to Jirka Hladky for discussing the idea.
+ hwloc-gather-topology may now gather I/O-related files on Linux when
--io is given. Only the linuxpci component supports discovering I/O
objects from these extended tarballs.
+ hwloc-annotate now supports --ri to remove/replace info attributes with
a given name.
+ hwloc-info supports "root" and "all" special locations for dumping
information about the root object.
+ lstopo now supports --append-legend to append custom lines of text
to the legend in the graphical output. Thanks to Jirka Hladky for
discussing the idea.
+ hwloc-calc and friends have a more robust parsing of locations given
on the command-line and they report useful error messages about it.
+ Add --whole-system to hwloc-bind, hwloc-calc, hwloc-distances and
hwloc-distrib, and add --restrict to hwloc-bind for uniformity among
tools.
* Misc
+ Calling hwloc_topology_load() or hwloc_topology_set_*() on an already
loaded topology now returns an error (deprecated since release 1.6.1).
+ Fix the initialisation of cpusets and nodesets in Group objects added
when inserting PCI hostbridges.
+ Never merge Group objects that were added explicitly by the user with
hwloc_custom_insert_group_object_by_parent().
+ Add a sanity check during dynamic plugin loading to prevent some
crashes when hwloc is dynamically loaded by another plugin mechanisms.
+ Add --with-hwloc-plugins-path to specify the install/load directories
of plugins.
+ Add the MICSerialNumber info attribute to the root object when running
hwloc inside a Xeon Phi to match the same attribute in the MIC OS device
when running in the host.
Version 1.7.2
-------------
* Do not create invalid block OS devices on very old Linux kernel such
as RHEL4 2.6.9.
* Fix PCI subvendor/device IDs.
* Fix the management of Misc objects inserted by parent.
Thanks to Jirka Hladky for reporting the problem.
* Add a Port<n>State into attribute to OpenFabrics OS devices.
* Add a MICSerialNumber info attribute to Xeon PHI/MIC OS devices.
* Improve verbose error messages when failing to load from XML.
reported in PR 49080. I did look in the package configury to figure
out which ones were mutually connected, but I may have gotten it
wrong as there's a monumental maze of m4 autotoolery.
---------------------
- Now compiles on GNU/kFreeBSD
- Pool: `AF_PIPE` address fixed so that it works on recent Windows versions
in combination with Python 2.7.7.
- Pool: Fix for `Supervisor object has no attribute _children` error.
- Pool: Fixed bug with human_status(None).
- Pool: shrink did not work properly if asked to remove more than 1 process.
mk-configure>=0.27.0 is required for build.
Option -X was introduced to paexec(1) for ignoring
calculator's stdout.
PAEXEC_ENV environment variable sets a list of variables passed to
the calculator.
PAEXEC_TRANSPORT environment variable sets the transport unless
option -t was applied.
PAEXEC_NODES environment variable sets the nodes unless
option -n was applied.
pareorder(1) is a synonym for paexec_reorder(1)
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
This seems to have been fixed in a previous version. At least "import
billiard" works from the interpreter. From CHANGES.txt:
- Fixes SemLock on Python 3.4 (Issue #107) when using
``forking_enable(False)``.
- Pool: Include more useful exitcode information when processes exit.
1) The shared library isn't installed with py33. The package uses a pure
python implementation;
2) The connection and reduction functions are installed in different
directory names depending on python major version. From CHANGES.txt:
3.3.0.16 - 2014-02-11
---------------------
- Previous release was missing the billiard.py3 package from MANIFEST
so the installation would not work on Python 3.
3.3.0.15 - 2014-02-10
---------------------
- Pool: Fixed "cannot join process not started" error.
- Now uses billiard.py2 and billiard.py3 specific packages that are installed
depending on the python version used.
This way the installation will not import version specific modules (and
possibly crash).
3.3.0.14 - 2014-01-17
---------------------
- Fixed problem with our backwards compatible ``bytes`` wrapper
(Issue #103).
- No longer expects frozen applications to have a valid ``__file__``
attribute.

methods
* distinst supports installation with install(1) for use with -local

* Security fixes
The first fix is for a trivial remote root by a valid user. The
others, including fixes for potential buffer overruns in daemon and
setuid programs, may or may not be exploitable.
* Sanitize the environment before executing remote startup programs etc.
Somewhat incompatible: LD_LIBRARY_PATH etc. may need to be set
differently. See the security notes in remote_startup(5) and
sge_conf(5). (CVE-2012-0208, thanks to William Hay)
* Don't write initial log messages in /tmp. Somewhat
incompatible: initial messages now in syslog.

(Not normally a security issue.)
* Bounds checking in replace_params
* Avoid execd crash and possible overruns
* Fixes for buffer overrun and other improvements for (setuid
program) sgepasswd
dsh is an implementation of a wrapper for executing multiple remote shell
(rsh/remsh/ssh) commands. rsh/remsh/ssh are wrappers for executing shell
(ksh/bash/zsh/tcsh/sh .. etc... ) on remote hosts.

- New pure-python implementation of ``Connection.send_offset``.
3.3.0.5 - 2013-11-11
--------------------
- All platforms except for Windows/PyPy/Jython now requires the C extension.
3.3.0.4 - 2013-11-11
--------------------
- Fixed problem with Python3 and setblocking.
3.3.0.3 - 2013-11-09
--------------------
- Now works on Windows again.
3.3.0.2 - 2013-11-08
--------------------
- ApplyResult.terminate() may be set to signify that the job
must not be executed. It can be used in combination with
Pool.terminate_job.
- Pipe/_SimpleQueue: Now supports rnonblock/wnonblock arguments
to set the read or write end of the pipe to be nonblocking.
- Pool: Log message included exception info but exception happened
in another process so the resulting traceback was wrong.
- Pool: Worker process can now prepare results before they are sent
back to the main process (using ``Worker.prepare_result``).
3.3.0.1 - 2013-11-04
--------------------
- Pool: New ``correlation_id`` argument to ``apply_async`` can be
used to set a related id for the ``ApplyResult`` object returned:
>>> r = pool.apply_async(target, args, kwargs, correlation_id='foo')
>>> r.correlation_id
'foo'
- Pool: New callback `on_process_exit` is called when a pool
process exits, with signature ``(pid, exitcode)``.
- Pool: Improved the too many restarts detection.
3.3.0.0 - 2013-10-14
--------------------
- Dual code base now runs on Python 2.6+ and Python 3.
- No longer compatible with Python 2.5
- Includes many changes from multiprocessing in 3.4.
- Now uses ``time.monotonic`` when available, also including
fallback implementations for Linux and OS X.
- No longer cleans up after receiving SIGILL, SIGSEGV or SIGFPE
- ``Finalize`` and ``register_after_fork`` is now aliases to multiprocessing.
It's better to import these from multiprocessing directly now
so that there aren't multiple registries.
- New `billiard.queues._SimpleQueue` that does not use semaphores.
- Pool: Can now be extended to support using multiple IPC queues.
- Pool: Can now use async I/O to write to pool IPC queues.
- Pool: New ``Worker.on_loop_stop`` handler can be used to add actions
at pool worker process shutdown.
Note that, like all finalization handlers, there is no guarantee that
this will be executed.
Based on work of Jason Bacon published in WIP.

========================
-- Fix issue with reconfig and GrpCPURunMins
-- Fix of wrong node/job state problem after reconfig

job arrays submitted to multiple partitions.
-- Enforce --ntasks-per-socket=1 job option when allocating by socket.
-- Validate permissions of key directories at slurmctld startup. Report
anything that is world writable.
-- Improve GRES support for CPU topology. Previous logic would pick CPUs then
reject jobs that can not match GRES to the allocated CPUs. New logic first
filters out CPUs that can not use the GRES, next picks CPUs for the job,
and finally picks the GRES that best match those CPUs.
-- Switch/nrt - Prevent invalid memory reference when allocating single adapter
per node of specific adapter type
-- CRAY - Make Slurm work with CLE 5.1.1
-- Fix segfault if submitting to multiple partitions and holding the job.

lengths.
-- If OverTimeLimit is defined do not declare failed those jobs that ended
in the OverTimeLimit interval.
* Changes in Slurm 2.6.1

-- slurmdbd - Allow job derived ec and comments to be modified by non-root
users.
-- Fix issue with job name being truncated to 24 chars when sending a mail
message.
-- Fix minor issues with spec file, missing files and including files
erroneously on a bluegene system.

-- CRAY - Fix srun --mem_bind=local option with launch/aprun.
-- PMI2 Corrected buffer size computation in the pmi2_api.c module.
-- GRES accounting data wrong in database: gres_alloc, gres_req, and gres_used
fields were empty if the job was not started immediately.
-- Fix sbatch and srun task count logic when --ntasks-per-node specified,
but no explicit task count.
-- Corrected the hdf5 profile user guide and the acct_gather.conf
documentation.
-- IPMI - Fix Math bug getting new wattage.

-- Corrected the sh5util program to print the header in the csv file
only once, set the debug messages at debug() level, make the argument
check case insensitive and avoid printing duplicate \n.
-- If cannot collect energy values send message to the controller
to drain the node and log error slurmd log file.
-- Handle complete removal of CPURunMins time at the end of the job instead
of at multifactor poll.
-- sview - Add missing debug_flag options.

-- sched/wiki2 - Insure that Moab gets current CPU load information.
-- Prevent infinite loop in parsing configuration if including file containing
one blank line.
-- Fix pack and unpack between 2.6 and 2.5.
-- Fix job state recovery logic in which a job's accounting frequency was
not set. This would result in a value of 65534 seconds being used (the
equivalent of NO_VAL in uint16_t), which could result in the job being
requeued or aborted.
-- Validate a job's accounting frequency at submission time rather than
waiting for it's initiation to possibly fail.
-- Fix CPURunMins if a job is requeued from a failed launch.
-- Fix in accounting_storage/filetxt to correct start times which sometimes
could end up before the job started.
-- Fix issue with potentially referencing past an array in parse_time()
-- CRAY - fix issue with accelerators on a cray when parsing BASIL 1.3 XML.
-- Fix issue with a 2.5 slurmstepd locking up when talking to a 2.6 slurmd.

overwritten by the parallel versions thus making it so we need handle
both cases.
-- ACCT_GATHER - handle suspending correctly for polling threads.
-- Make SLURM_DISTRIBUTION env var hold both types of distribution if
specified.
-- Remove hardcoded /usr/local from slurm.spec.
-- Modify slurmctld locking to improve performance under heavy load with
very large numbers of batch job submissions or job cancellations.
-- sstat - Fix issue where if -j wasn't given allow last argument to be checked
for as the job/step id.
-- IPMI - fix adjustment on poll when using EnergyIPMICalcAdjustment.
* Changes in Slurm 2.6.0rc1
===========================
-- Added helper script for launching symmetric and MIC-only MPI tasks within
SLURM (in contribs/mic/mpirun-mic).
-- Change maximum delay for state save from 2 secs to 5 secs. Make timeout
configurable at build time by defining SAVE_MAX_WAIT.
-- Modify slurmctld data structure locking to interleave read and write
locks rather than always favor write locks over read locks.
-- Added sacct format option of "ALL" to print all fields.
-- Deprecate the SchedulerParameters value of "interval" use "bf_interval"
instead as documented.
-- Add acct_gather_profile/hdf5 to profile jobs with hdf5
-- Added MaxCPUsPerNode partition configuration parameter. This can be
especially useful to schedule systems with GPUs.
-- Permit "scontrol reboot_node" for nodes in MAINT reservation.
-- Added "PriorityFlags" value of "SMALL_RELATIVE_TO_TIME". If set, the job's
size component will be based upon not the job size alone, but the job's
size divided by it's time limit.
-- Added sbatch option "--ignore-pbs" to ignore "#PBS" options in the batch
script.
-- Rename slurm_step_ctx_params_t field from "mem_per_cpu" to "pn_min_memory".
Job step now accepts memory specification in either per-cpu or per-node
basis.
-- Add ability to specify host repitition count in the srun hostfile (e.g.
"host1*2" is equivalent to "host1,host1").
* Changes in Slurm 2.6.0pre3
============================
-- Add milliseconds to default log message header (both RFC 5424 and ISO 8601
time formats). Disable milliseconds logging using the configure
parameter "--disable-log-time-msec". Default time format changes to
ISO 8601 (without time zone information). Specify "--enable-rfc5424time"
to restore the time zone information.
-- Add username (%u) to the filename pattern in the batch script.
-- Added options for front end nodes of AllowGroups, AllowUsers, DenyGroups,
and DenyUsers.
-- Fix sched/backfill logic to initiate jobs with maximum time limit over the
partition limit, but the minimum time limit permits it to start.
-- gres/gpu - Fix for gres.conf file with multiple files on a single line
using a slurm expression (e.g. "File=/dev/nvidia[0-1]").
-- Replaced ipmi.conf with generic acct_gather.conf file for all acct_gather
plugins. For those doing development to use this follow the model set
forth in the acct_gather_energy_ipmi plugin.
-- Added more options to update a step's information
-- Add DebugFlags=ThreadID which will print the thread id of the calling
thread.
-- CRAY - Allocate whole node (CPUs) in reservation despite what the
user requests. We have found any srun/aprun afterwards will work on a
subset of resources.
* Changes in Slurm 2.6.0pre2
============================
-- Do not purge inactive interactive jobs that lack a port to ping (added
for MR+ operation).
-- Advanced reservations with hostname and core counts now supports asymetric
reservations (e.g. specific different core count for each node).
-- Added slurmctld/dynalloc plugin for MapReduce+ support.
-- Added "DynAllocPort" configuration parameter.
-- Added partition paramter of SelectTypeParameters to override system-wide
value.
-- Added cr_type to partition_info data structure.
-- Added allocated memory to node information available (within the existing
select_nodeinfo field of the node_info_t data structure). Added Allocated
Memory to node information displayed by sview and scontrol commands.
-- Make sched/backfill the default scheduling plugin rather than sched/builtin
(FIFO).
-- Added support for a job having different priorities in different partitions.
-- Added new SchedulerParameters configuration parameter of "bf_continue"
which permits the backfill scheduler to continue considering jobs for
backfill scheduling after yielding locks even if new jobs have been
submitted. This can result in lower priority jobs from being backfill
scheduled instead of newly arrived higher priority jobs, but will permit
more queued jobs to be considered for backfill scheduling.
-- Added support to purge reservation records from accounting.
-- Cray - Add support for Basil 1.3
* Changes in SLURM 2.6.0pre1
============================
-- Add "state" field to job step information reported by scontrol.
-- Notify srun to retry step creation upon completion of other job steps
rather than polling. This results in much faster throughput for job step
execution with --exclusive option.
-- Added "ResvEpilog" and "ResvProlog" configuration parameters to execute a
program at the beginning and end of each reservation.
-- Added "slurm_load_job_user" function. This is a variation of
"slurm_load_jobs", but accepts a user ID argument, potentially resulting
in substantial performance improvement for "squeue --user=ID"
-- Added "slurm_load_node_single" function. This is a variation of
"slurm_load_nodes", but accepts a node name argument, potentially resulting
in substantial performance improvement for "sinfo --nodes=NAME".
-- Added "HealthCheckNodeState" configuration parameter identify node states
on which HealthCheckProgram should be executed.
-- Remove sacct --dump --formatted-dump options which were deprecated in
2.5.
-- Added support for job arrays (phase 1 of effort). See "man sbatch" option
-a/--array for details.
-- Add new AccountStorageEnforce options of 'nojobs' and 'nosteps' which will
allow the use of accounting features like associations, qos and limits but
not keep track of jobs or steps in accounting.
-- Cray - Add new cray.conf parameter of "AlpsEngine" to specify the
communication protocol to be used for ALPS/BASIL.
-- select/cons_res plugin: Correction to CPU allocation count logic in for
cores without hyperthreading.
-- Added new SelectTypeParameter value of "CR_ALLOCATE_FULL_SOCKET".
-- Added PriorityFlags value of "TICKET_BASED" and merged priority/multifactor2
plugin into priority/multifactor plugin.
-- Add "KeepAliveTime" configuration parameter controlling how long sockets
used for srun/slurmstepd communications are kept alive after disconnect.
-- Added SLURM_SUBMIT_HOST to salloc, sbatch and srun job environment.
-- Added SLURM_ARRAY_TASK_ID to environment of job array.
-- Added squeue --array/-r option to optimize output for job arrays.
-- Added "SlurmctldPlugstack" configuration parameter for generic stack of
slurmctld daemon plugins.
-- Removed contribs/arrayrun tool. Use native support for job arrays.
-- Modify default installation locations for RPMs to match "make install":
_prefix /usr/local
_slurm_sysconfdir %{_prefix}/etc/slurm
_mandir %{_prefix}/share/man
_infodir %{_prefix}/share/info
-- Add acct_gather_energy/ipmi which works off freeipmi for energy gathering
* Changes in Slurm 2.5.8
========================
-- Fix for slurmctld segfault on NULL front-end reason field.
-- Avoid gres step allocation errors when a job shrinks in size due to either
down nodes or explicit resizing. Generated slurmctld errors of this type:
"step_test ... gres_bit_alloc is NULL"
-- Fix bug that would leak memory and over-write the AllowGroups field if on
"scontrol reconfig" when AllowNodes is manually changed using scontrol.
-- Get html/man files to install in correct places with rpms.
-- Remove --program-prefix from spec file since it appears to be added by
default and appeared to break other things.
-- Updated the automake min version in autogen.sh to be correct.
-- Select/cons_res - Correct total CPU count allocated to a job with
--exclusive and --cpus-per-task options
-- switch/nrt - Don't allocate network resources unless job step has 2+ nodes.
-- select/cons_res - Avoid extraneous "oversubscribe" error messages.
-- Reorder get config logic to avoid deadlock.
-- Enforce QOS MaxCPUsMin limit when job submission contains no user-specified
time limit.
-- EpilogSlurmctld pthread is passed required arguments rather than a pointer
to the job record, which under some conditions could be purged and result
in an invalid memory reference.
* Changes in Slurm 2.5.7
========================
-- Fix for linking to the select/cray plugin to not give warning about
undefined variable.
-- Add missing symbols to the xlator.h
-- Avoid placing pending jobs in AdminHold state due to backfill scheduler
interactions with advanced reservation.
-- Accounting - make average by task not cpu.
-- CRAY - Change logging of transient ALPS errors from error() to debug().
-- POE - Correct logic to support poe option "-euidevice sn_all" and
"-euidevice sn_single".
-- Accounting - Fix minor initialization error.
-- POE - Correct logic to support srun network instances count with POE.
-- POE - With the srun --launch-cmd option, report proper task count when
the --cpus-per-task option is used without the --ntasks option.
-- POE - Fix logic binding tasks to CPUs.
-- sview - Fix race condition where new information could of slipped past
the node tab and we didn't notice.
-- Accounting - Fix an invalid memory read when slurmctld sends data about
start job to slurmdbd.
-- If a prolog or epilog failure occurs, drain the node rather than setting it
down and killing all of its jobs.
-- Priority/multifactor - Avoid underflow in half-life calculation.
-- POE - pack missing variable to allow fanout (more than 32 nodes)
-- Prevent clearing reason field for pending jobs. This bug was introduced in
v2.5.5 (see "Reject job at submit time ...").
-- BGQ - Fix issue with preemption on sub-block jobs where a job would kill
all preemptable jobs on the midplane instead of just the ones it needed to.
-- switch/nrt - Validate dynamic window allocation size.
-- BGQ - When --geo is requested do not impose the default conn_types.
-- CRAY - Support CLE 4.2.0
-- RebootNode logic - Defers (rather than forgets) reboot request with job
running on the node within a reservation.
-- switch/nrt - Correct network_id use logic. Correct support for user sn_all
and sn_single options.
-- sched/backfill - Modify logic to reduce overhead under heavy load.
-- Fix job step allocation with --exclusive and --hostlist option.
-- Select/cons_res - Fix bug resulting in error of "cons_res: sync loop not
progressing, holding job #"
-- checkpoint/blcr - Reset max_nodes from zero to NO_VAL on job restart.
-- launch/poe - Fix for hostlist file support with repeated host names.
-- priority/multifactor2 - Prevent possible divide by zero.
-- srun - Don't check for executable if --test-only flag is used.
-- energy - On a single node only use the last task for gathering energy.
Since we don't currently track energy usage per task (only per step).
Otherwise we get double the energy.
* Changes in Slurm 2.5.6
========================
-- Gres fix for requeued jobs.
-- Gres accounting - Fix regression in 2.5.5 for keeping track of gres
requested and allocated.
* Changes in Slurm 2.5.5
========================
-- Fix for sacctmgr add qos to handle the 'flags' option.
-- Export SLURM_ environment variables from sbatch, even if "--export"
option does not explicitly list them.
-- If node is in more than one partition, correct counting of allocated CPUs.
-- If step requests more CPUs than possible in specified node count of job
allocation then return ESLURM_TOO_MANY_REQUESTED_CPUS rather than
ESLURM_NODES_BUSY and retrying.
-- CRAY - Fix SLURM_TASKS_PER_NODE to be set correctly.
-- Accounting - more checks for strings with a possible `'` in it.
-- sreport - Fix by adding planned down time to utilization reports.

-- Cray - Disable enforcement of MaxTasksPerNode, which is not applicable
with launch/aprun.
-- Accounting - When rolling up data from past usage ignore "idle" time from
a reservation when it has the "Ignore_Jobs" flag set. Since jobs could run
outside of the reservation in it's nodes without this you could have
double time.
-- Accounting - Minor fix to avoid reuse of variable erroneously.
-- Reject job at submit time if the node count is invalid. Previously such a
job submitted to a DOWN partition would be queued.
-- Purge vestigial job scripts when the slurmd cold starts or slurmstepd
terminates abnormally.
-- Add support for FreeBSD.
-- Add sanity check for NULL cluster names trying to register.
-- BGQ - Push action 'D' info to scontrol for admins.
-- Reset a job's reason from PartitionDown when the partition is set up.
-- BGQ - Handle issue where blocks would have a pending job on them and
while it was free cnodes would go into software error and kill the job.
-- BGQ - Fix issue where if for some reason we are freeing a block with
a pending job on it we don't kill the job.
-- BGQ - Fix race condition were a job could of been removed from a block
without it still existing there. This is extremely rare.
-- BGQ - Fix for when a step completes in Slurm before the runjob_mux notifies
the slurmctld there were software errors on some nodes.
-- BGQ - Fix issue on state recover if block states are not around
and when reading in state from DB2 we find a block that can't be created.
You can now do a clean start to rid the bad block.
-- Modify slurmdbd to retransmit to slurmctld daemon if it is not responding.
-- BLUEGENE - Fix issue where when doing backfill preemptable jobs were
never looked at to determine eligibility of backfillable job.
-- Cray/BlueGene - Disable srun --pty option unless LaunchType=launch/slurm.
-- CRAY - Fix sanity check for systems with more than 32 cores per node.

isn't a sub-block job.
-- Cray - avoid check of macro versions of CLE for version 5.0.
-- CRAY - Fix memory issue with reading in the cray.conf file.
-- CRAY - If hostlist is given with srun make sure the node count is the same
as the hosts given.
-- CRAY - If task count specified, but no tasks-per-node, then set the tasks
per node in the BASIL reservation request.
-- CRAY - fix issue with --mem option not giving correct amount of memory
per cpu.
-- CRAY - Fix if srun --mem is given outside an allocation to set the
APRUN_DEFAULT_MEMORY env var for aprun. This scenario will not display
the option when used with --launch-cmd.
-- Change sview to use GMutex instead of GStaticMutex
-- CRAY - set APRUN_DEFAULT_MEMROY instead of CRAY_AUTO_APRUN_OPTIONS
-- sview - fix issue where if a partition was completely in one state the
cpu count would be reflected correctly.
-- BGQ - fix for handling half rack system in STATIC of OVERLAP mode to
implicitly create full system block.
-- CRAY - Dynamically create BASIL XML buffer to resize as needed.

to attempt to signal tasks on the frontend node.
-- Cray - when a step is requested count other steps running on nodes in the
allocation as taking up the entire node instead of just part of the node
allocated. And always enforce exclusive on a step request.
-- Cray - display correct nodelist, node/cpu count on steps.
* Changes in Slurm 2.5.4
========================
-- Fix bug in PrologSlurmctld use that would block job steps until node
responds.
-- CRAY - If a partition has MinNodes=0 and a batch job doesn't request nodes
put the allocation to 1 instead of 0 which prevents the allocation to
happen.

the user commands.
-- When asking for job states with sacct, default to 'now' instead of midnight
of the current day.
-- Fix for handling a test-only job or immediate job that fails while being

-- In select/cons_res, correct logic to allocate whole sockets to jobs. Work
by Magnus Jonsson, Umea University.
-- In select/cons_res, correct logic when job removed from only some nodes.
-- Avoid apparent kernel bug in 2.6.32 which apparently is solved in
at least 3.5.0. This avoids a stack overflow when running jobs on
more than 120k nodes.
-- BLUEGENE - If we made a block that isn't runnable because of a overlapping
block, destroy it correctly.
-- Switch/nrt - Dynamically load libnrt.so from within the plugin as needed.
This eliminates the need for libnrt.so on the head node.
-- BLUEGENE - Fix in reservation logic that could cause abort.
* Changes in SLURM 2.5.1

slurm.conf with NodeAddr's signals going to a step could be handled
incorrectly.

============================
-- Modify sbcast logic to survive slurmd daemon restart while file a
transmission is in progress.
-- Add retry logic to munge encode/decode calls. This is needed if the munge
deamon is under very heavy load (e.g. with 1000 slurmd daemons per compute
node).
-- Add launch and acct_gather_energy plugins to RPMs.
-- Restore support for srun "--mpi=list" option.
-- CRAY - Introduce step accounting for a Cray.

an aborted slurmstepd can cause the srun process to hang indefinitely.
-- ENERGY - RAPL - alter code to close open files (and only open them once
where needed)

-- Accounting - Change empty jobacctinfo structs to not actually be used
instead of putting 0's into the database we put NO_VALS and have sacct
figure out jobacct_gather wasn't used.
-- Cray - Prevent calling basil_confirm more than once per job using a flag.
-- Fix bug with topology/tree and job with min-max node count. Now try to
get max node count rather than minimizing leaf switches used.
-- Add AccountingStorageEnforce=safe option to provide method to avoid jobs
launching that wouldn't be able to run to completion because of a
GrpCPUMins limit.
-- Add support for RFC 5424 timestamps in logfiles. Disable with configuration

=============================
-- When running with multiple slurmd daemons per node, enable specifying a
range of ports on a single line of the node configuration in slurm.conf.

a reservation and automatically change the reservation when nodes are
added to or removed from the reservation. Based upon work by
Bill Brophy, Bull.
-- Add support for advanced reservation for specific cores rather than whole
nodes. Current limiations: homogeneous cluster, nodes idle when reservation
created, and no more than one reservation per node. Code is still under
development. Work by Alejandro Lucero Palau, et. al, BSC.
-- Add DebugFlag of Switch to log switch plugin details.
-- Correct job node_cnt value in job completion plugin when job fails due to
down node. Previously was too low by one.
-- Add new srun option --cpu-freq to enable user control over the job's CPU
frequency and thus it's power consumption. NOTE: cpu frequency is not
currently preserved for jobs being suspended and later resumed. Work by
Don Albert, Bull.
-- Add node configuration information about "boards" and optimize task
placement on minimum number of boards. Work by Rod Schultz, Bull.
* Changes in SLURM 2.5.0.pre1

"name:used/total"
-- Changed jobacct_gather plugin infrastructure to be cleaner and easier to
maintain.

* Changes in SLURM 2.4.5
========================
-- Cray - On job kill requeust, send SIGCONT, SIGTERM, wait KillWait and send
SIGKILL. Previously just sent SIGKILL to tasks.
-- BGQ - Fix issue when running srun outside of an allocation and only
specifying the number of tasks and not the number of nodes.
-- BGQ - validate correct ntasks_per_node
-- BGQ - when srun -Q is given make runjob be quiet
-- Modify use of OOM (out of memory protection) for Linux 2.6.36 kernel
or later. NOTE: If you were setting the environment variable
SLURMSTEPD_OOM_ADJ=-17, it should be set to -1000 for Linux 2.6.36 kernel
or later.
-- BGQ - Fix job step timeout actually happen when done from within an
allocation.
-- Reset node MAINT state flag when a reservation's nodes or flags change.
-- Accounting - Fix issue where QOS usage was being zeroed out on a
slurmctld restart.
-- BGQ - Add 64 tasks per node as a valid option for srun when used with
overcommit.
-- BLUEGENE - With Dynamic layout mode - Fix issue where if a larger block
was already in error and isn't deallocating and underlying hardware goes
bad one could get overlapping blocks in error making the code assert when
a new job request comes in.
-- BGQ - handle pending actions on a block better when trying to deallocate it.
-- Accounting - Fixed issue where if nodenames have changed on a system and
you query against that with -N and -E you will get all jobs during that
time instead of only the ones running on -N.
-- BGP - Fix for HTC mode
-- Accounting - If a job start message fails to the SlurmDBD reset the db_inx
so it gets sent again. This isn't a major problem since the start will
happen when the job ends, but this does make things cleaner.
-- If an salloc is waiting for an allocation to happen and is canceled by the
user mark the state canceled instead of completed.
-- Fix issue in accounting if a user puts a '\' in their job name.
-- Accounting - Fix for if asking for users or accounts that were deleted
with associations get the deleted associations as well.

job on future step creation attempts.
* Changes in SLURM 2.4.4
========================
-- BGQ - minor fix to make build work in emulated mode.
-- BGQ - Fix if large block goes into error and the next highest priority jobs
are planning on using the block. Previously it would fail those jobs
erroneously.
-- BGQ - Fix issue when a cnode going to an error (not SoftwareError) state
with a job running or trying to run on it.
-- Execute slurm_spank_job_epilog when there is no system Epilog configured.
-- Fix for srun --test-only to work correctly with timelimits
-- BGQ - If a job goes away while still trying to free it up in the
database, and the job is running on a small block make sure we free up
the correct node count.
-- BGQ - Logic added to make sure a job has finished on a block before it is
purged from the system if its front-end node goes down.
-- Modify strigger so that a filter option of "--user=0" is supported.
-- Correct --mem-per-cpu logic for core or socket allocations with multiple
threads per core.
-- Fix for older < glibc 2.4 systems to use euidaccess() instead of eaccess().
-- BLUEGENE - Do not alter a pending job's node count when changing it's
partition.
-- BGQ - Add functionality to make it so we track the actions on a block.
This is needed for when a free request is added to a block but there are
jobs finishing up so we don't start new jobs on the block since they will
fail on start.
-- BGQ - Fixed InactiveLimit to work correctly to avoid scenarios where a
user's pending allocation was started with srun and then for some reason
the slurmctld was brought down and while it was down the srun was removed.
-- Fixed InactiveLimit math to work correctly
-- BGQ - Add logic to make it so blocks can't use a midplane with a nodeboard
in error for passthrough.

for passthrough gets removed on a dynamic system.
-- BGQ - Fix for printing realtime server debug correctly.

-- Correction to slurmdbd communications failure handling logic, incorrect
error codes returned in some cases.
* Changes in SLURM 2.4.3
========================
-- Accounting - Fix so complete 32 bit numbers can be put in for a priority.
-- cgroups - fix if initial directory is non-existent SLURM creates it
correctly. Before the errno wasn't being checked correctly
-- BGQ - fixed srun when only requesting a task count and not a node count
to operate the same way salloc or sbatch did and assign a task per cpu
by default instead of task per node.
-- Fix salloc --gid to work correctly. Reported by Brian Gilmer
-- BGQ - fix smap to set the correct default MloaderImage
-- BLUEGENE - updated documentation.
-- Close the batch job's environment file when it contains no data to avoid
leaking file descriptors.
-- Fix sbcast's credential to last till the end of a job instead of the
previous 20 minute time limit. The previous behavior would fail for
large files 20 minutes into the transfer.
-- Return ESLURM_NODES_BUSY rather than ESLURM_NODE_NOT_AVAIL error on job
submit when required nodes are up, but completing a job or in exclusive
job allocation.
-- Add HWLOC_FLAGS so linking to libslurm works correctly
-- BGQ - If using backfill and a shared block is running at least one job
and a job comes through backfill and can fit on the block without ending
jobs don't set an end_time for the running jobs since they don't need to
end to start the job.
-- Initialize bind_verbose when using task/cgroup.
-- BGQ - Fix for handling backfill much better when sharing blocks.
-- BGQ - Fix for making small blocks on first pass if not sharing blocks.
-- BLUEGENE - Remove force of default conn_type instead of leaving NAV
when none are requested. The Block allocator sets it up temporarily so
this isn't needed.

static blocks.
-- Fix to mysql plugin during rollup to only query suspended table when jobs
reported some suspended time.
-- Fix compile with glibc 2.16 (Kacper Kowalik)

running on it are preemptable by scheduling job.
-- proctrack/cgroup: Exclude internal threads from "scontrol list pids".
Patch from Matthieu Hautreux, CEA.
-- Memory leak fixed for select/linear when preempting jobs.
-- Fix if updating begin time of a job to update the eligible time in
accounting as well.
-- BGQ - make it so you can signal steps when signaling the job allocation.

-- BGQ - Handle issue of speed and mutexes when polling instead of using the
realtime server.
-- BGQ - Fix minor sorting issue with sview when sorting by midplanes.
-- Accounting - Fix for handling per user max node/cpus limits on a QOS
correctly for current job.
-- Update documentation for -/+= when updating a reservation's
users/accounts/flags
-- Update pam module to work if using aliases on nodes instead of actual
host names.
-- Correction to task layout logic in select/cons_res for job with minimum
and maximum node count.
-- BGQ - Put final poll after realtime comes back into service to avoid
having the realtime server go down over and over again while waiting
for the poll to finish.
-- task/cgroup/memory - ensure that ConstrainSwapSpace=no is correctly
handled. Work by Matthieu Hautreux, CEA.

========================
-- BLUEGENE - Correct potential deadlock issue when hardware goes bad and
there are jobs running on that hardware.
-- If job is submitted to more than one partition, it's partition pointer can
be set to an invalid value. This can result in the count of CPUs allocated
on a node being bad, resulting in over- or under-allocation of its CPUs.
Patch by Carles Fenoy, BSC.
-- Fix bug in task layout with select/cons_res plugin and --ntasks-per-node
option. Patch by Martin Perry, Bull.
-- BLUEGENE - remove race condition where if a block is removed while waiting
for a job to finish on it the number of unused cpus wasn't updated
correctly.
-- BGQ - make sure we have a valid block when creating or finishing a step
allocation.
-- BLUEGENE - If a large block (> 1 midplane) is in error and underlying
hardware is marked bad remove the larger block and create a block over
just the bad hardware making the other hardware available to run on.
-- BLUEGENE - Handle job completion correctly if an admin removes a block
where other blocks on an overlapping midplane are running jobs.
-- BLUEGENE - correctly remove running jobs when freeing a block.
-- BGQ - correct logic to place multiple (< 1 midplane) steps inside a
multi midplane block allocation.
-- BGQ - Make it possible for a multi midplane allocation to run on more
than 1 midplane but not the entire allocation.
-- BGL - Fix for syncing users on block from Tim Wickberg
-- Fix initialization of protocol_version for some messages to make sure it
is always set when sending or receiving a message.
-- Reset backfilled job counter only when explicitly cleared using scontrol.
Patch from Alejandro Lucero Palau, BSC.
-- BLUEGENE - Fix for handling blocks when a larger block will not free and
while it is attempting to free underlying hardware is marked in error
making small blocks overlapping with the freeing block. This only
applies to dynamic layout mode.
-- Cray and BlueGene - Do not treat lack of usable front-end nodes when
slurmctld deamon starts as a fatal error. Also preserve correct front-end
node for jobs when there is more than one front-end node and the slurmctld
daemon restarts.
-- Correct parsing of srun/sbatch input/output/error file names so that only
the name "none" is mapped to /dev/null and not any file name starting
with "none" (e.g. "none.o").
-- BGQ - added version string to the load of the runjob_mux plugin to verify
the current plugin has been loaded when using runjob_mux_refresh_config
-- CGROUPS - Use system mount/umount function calls instead of doing fork
exec of mount/umount from Janne Blomqvist.
-- BLUEGENE - correct start time setup when no jobs are blocking the way
from Mark Nelson
-- Fixed sacct --state=S query to return information about suspended jobs
current or in the past.
-- FRONTEND - Made error warning more apparent if a frontend node isn't
configured correctly.
-- BGQ - update documentation about runjob_mux_refresh_config which works
correctly as of IBM driver V1R1M1 efix 008.
This release of paexec was successfully tested on the following
platforms: NetBSD-6.1/amd64, OpenBSD-5.3/i386, FreeBSD-8.3/i386,
Solaris-10/sparc, Solaris-11/amd64 and diverse Linux/{i386,amd64}.
paexec is now selfcontained, libmaa is not needed anymore.
Presentation paexec.pdf was added to presentation/. I hope it will
help easier understand how "paexec" works. It is installed to
${DOCDIR}.
paexec:
- POSIX-2008 getline(3) is used for reading lines
instead of home-made function.
- t '' is equivalent to "no transport", spaces are trimmed.
- "-n +NNN" has higher priority than -t, i.e. if they both are
specified, transport is ignored.
- Fix for -W1.
- Environment variable PAEXEC_EOT was introduced.
- Option -y was added to paexec(1) and paexec_reorder(1).
- Option -C was added to paexec(1).
paexec_reorder:
- Option -x was added to paexec_reorder(1).
A number of fixes and improvements in regression tests.

billiard is a fork of the Python 2.7 multiprocessing package. The
multiprocessing package itself is a renamed and updated version of R Oudkerk's
pyprocessing package. This standalone variant is intended to be compatible with
Python 2.4 and 2.5, and will draw it's fixes/improvements from python-trunk.
* Also it is a fork of the multiprocessin backport package by Christian Heims;
* It includes the no-execv patch contributed by R. Oudkerk;
* And the Pool improvements previously located in Celery;
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.

+ Add GPU OS devices such as ":0.0" for NVIDIA X11 displays.
+ Add GPU OS devices such as "nvml0" for NVIDIA GPUs.
Thanks to Marwan Abdellah and Stefan Eilemann for helping.
These new OS devices have some string info attributes such as CoProcType,
GPUModel, etc. to better identify them.
See the I/O Devices and Attributes documentation sections for details.
* New components
+ Add the "opencl", "cuda", "nvml" and "gl" components for I/O device
discovery.
+ "nvml" also improves the discovery of NVIDIA GPU PCIe link speed.
All of these new components may be built as plugins. They may also be
disabled entirely by passing --disable-opencl/cuda/nvml/gl to configure.
See the I/O Devices, Components and Plugins, and FAQ documentation
sections for details.
* API
+ Add hwloc_topology_get_flags().
+ Add hwloc/plugins.h for building external plugins.
See the Adding new discovery components and plugins section.
* Interoperability
+ Add hwloc/opencl.h, hwloc/nvml.h, hwloc/gl.h and hwloc/intel-mic.h
to retrieve the locality of OS devices that correspond to AMD OpenCL
GPU devices or indexes, to NVML devices or indexes, to NVIDIA X11
displays, or to Intel Xeon Phi (MIC) device indexes.
+ Add new helpers in hwloc/cuda.h and hwloc/cudart.h to convert
between CUDA devices or indexes and hwloc OS devices.
+ Add hwloc_ibv_get_device_osdev() and clarify the requirements
of the OpenFabrics Verbs helpers in hwloc/openfabrics-verbs.h.
* Tools
+ hwloc-info is not only a synonym of lstopo -s anymore, it also
dumps information about objects given on the command-line.
* Documentation
+ Add a section "Existing components and plugins".
+ Add a list of common OS devices in section "Software devices".
+ Add a new FAQ entry "Why is lstopo slow?" about lstopo slowness
issues because of GPUs.
+ Clarify the documentation of inline helpers in hwloc/myriexpress.h
and hwloc/openfabrics-verbs.h.
* Misc
+ Improve cache detection on AIX.
+ The HWLOC_COMPONENTS variable now excludes the components whose
names are prefixed with '-'.
+ lstopo --ignore PU now works when displaying the topology in
graphical and textual mode (not when exporting to XML).
+ The `libpci' component is now called `pci' but the old name is still
accepted in the HWLOC_COMPONENTS variable for backward compatibility.
File too long (should be no more than 24 lines).
Line too long (should be no more than 80 characters).
Trailing empty lines.
Trailing white-space.
Trucated the long files as best as possible while preserving the most info
contained in them.

v1.5 is a major new release series. It includes many new features and
changes over the v1.4.x series. The most noticeable changes are the
addition of the lstopo-no-graphics program (which does require any
heavy external library such as Cairo) and the discovery of instruction
caches. There are also many small improvements to all backends, and
some deprecated features have been removed.
Version 1.5.0
-------------
* Backends
+ Do not limit the number of processors to 1024 on Solaris anymore.
+ Gather total machine memory on FreeBSD.
+ XML topology files do not depend on the locale anymore. Float numbers
such as NUMA distances or PCI link speeds now always use a dot as a
decimal separator.
+ Add instruction caches detection on Linux, AIX, Windows and Darwin.
+ Add get_last_cpu_location() support for the current thread on AIX.
+ Support binding on AIX when threads or processes were bound with
bindprocessor(). Thanks to Hendryk Bockelmann for reporting the issue
and testing patches, and to Farid Parpia for explaining the binding
interfaces.
+ Improve AMD topology detection in the x86 backend (for FreeBSD) using
the topoext feature.
* API
+ Increase HWLOC_API_VERSION to 0x00010500 so that API changes may be
detected at build-time.
+ Add a cache type attribute describind Data, Instruction and Unified
caches. Caches with different types but same depth (for instance L1d
and L1i) are placed on different levels.
+ Add hwloc_get_cache_type_depth() to retrieve the hwloc level depth of
of the given cache depth and type, for instance L1i or L2.
It helps disambiguating the case where hwloc_get_type_depth() returns
HWLOC_TYPE_DEPTH_MULTIPLE.
+ Instruction caches are ignored unless HWLOC_TOPOLOGY_FLAG_ICACHES is
passed to hwloc_topology_set_flags() before load.
+ Add hwloc_ibv_get_device_osdev_by_name() OpenFabrics helper in
openfabrics-verbs.h to find the hwloc OS device object corresponding to
an OpenFabrics device.
* Tools
+ Add lstopo-no-graphics, a lstopo built without graphical support to
avoid dependencies on external libraries such as Cairo and X11. When
supported, graphical outputs are only available in the original lstopo
program.
- Packagers splitting lstopo and lstopo-no-graphics into different
packages are advised to use the alternatives system so that lstopo
points to the best available binary.
+ Instruction caches are enabled in lstopo by default. User --no-icaches
to disable them.
+ Add -t/--threads to show threads in hwloc-ps.
* Removal of obsolete components
+ Remove the old cpuset interface (hwloc/cpuset.h) which is deprecated and
superseded by the bitmap API (hwloc/bitmap.h) since v1.1.
hwloc_cpuset and nodeset types are still defined, but all hwloc_cpuset_*
compatibility wrappers are now gone.
+ Remove Linux libnuma conversion helpers for the deprecated and
broken nodemask_t interface.
+ Remove support for "Proc" type name, it was superseded by "PU" in v1.0.
+ Remove hwloc-mask symlinks, it was replaced by hwloc-calc in v1.0.
* Misc
+ Fix PCIe 3.0 link speed computation.
+ Non-printable characters are dropped from strings during XML export.
+ Fix importing of escaped characters with the minimalistic XML backend.
+ Assert hwloc_is_thissystem() in several I/O related helpers.
+ Fix some memory leaks in the x86 backend for FreeBSD.
+ Minor fixes to ease native builds on Windows.
+ Limit the number of retries when operating on all threads within a
process on Linux if the list of threads is heavily getting modified.
paexec:
- Option -x was added. With its help paexec can run one command
per task. If -g is also specified, command's exit status is
analysed. Appropriate task and dependants are marked as "failed"
if it is non-zero.
- First character of -n argument must be alphanumeric, `+', `_',
`:' or `/'. Other symbols are reserved for future extentions.
- With '-n :filename' paexec reads a list of nodes from the
specified file.
- With a help of new option '-m t=<eot>' end of task string
may be specified, which is an empty line by default.
- Option -md=<delim> was added that overrides the default
delimiter (space character) between tasks in graph mode (-g).
- Output line that contains failed dependants no longer ends with
unnecessary space.
- Long options were completely removed.
paexec_reorder:
- Fix. "paexec_reorder -g" now handles correctly failed tasks'
output. One extra line after "fatal" is expected.
- Options -m was added. It does the same things as paexec's -m.
More examples of use and regression tests.
Documentation update, clean-ups and improvements.
Regression tests:
- Signals handling was fixed in.
- LC_ALL is always set to C in regression tests, this fixes some
problems in internationalized environment.

production as it isn't currently complete and doesn't provide an equivalent
substitution for jobacct_gather/linux yet. Work by Martin Perry, Bull.
Disable automatic detection of SGE and SLURM to avoid PLIST divergence.
Changes in OpenMPI 1.6
v1.6 is a major release; it effectively deprecates both the v1.4.x
and v1.5.x series, and replaces v1.4.x as the current "super stable" series.
A forthcoming v1.7 series will become the new "feature" series.
*All users* -- including production users and downstream providers --
are encouraged to upgrade to v1.6.
Note that v1.6 is ABI compatible with the entire v1.5.x series,
but is not ABI compatible with the v1.4.x series.
See http://www.open-mpi.org/software/ompi/versions/ for a description
of Open MPI's release methodology.
Here is a list of changes in v1.6 as compared to v1.5.5:
- Fix some process affinity issues. When binding a process, Open MPI
will now bind to all available hyperthreads in a core (or socket,
depending on the binding options specified).
--> Note that "mpirun --bind-to-socket ..." does not work on POWER6-
and POWER7-based systems with some Linux kernel versions. See
the FAQ on the Open MPI web site for more information.
- Add support for ARM5 and ARM6 (in addition to the existing ARM7
support). Thanks to Evan Clinton for the patch.
- Minor Mellanox MXM fixes.
- Properly detect FDR10, FDR, and EDR OpenFabrics devices.
- Minor fixes to the mpirun(1) and MPI_Comm_create(3) man pages.
- Prevent segv if COMM_SPAWN_MULTIPLE fails. Thanks to Fujitsu for
the patch.
- Disable interposed memory management in fakeroot environments. This
fixes a problem in some build environments.
- Minor hwloc updates.
- Array versions of MPI_TEST and MPI_WAIT with a count==0 will now
return immediately with MPI_SUCCESS. Thanks to Jeremiah Willcock
for the suggestion.
- Update VampirTrace to v5.12.2.
- Properly handle forwarding stdin to all processes when "mpirun
--stdin all" is used.
- Workaround XLC assembly bug.
- OS X Tiger (10.3) has not been supported for a while, so forcibly
abort configure if we detect it.
- Fix segv in the openib BTL when running on SPARC 64 systems.
- Fix some include file ordering issues on some BSD-based platforms.
Thanks to Paul Hargove for this (and many, many other) fixes.
- Properly handle .FALSE. return parameter value to attribute copy
callback functions.
- Fix a bunch of minor C++ API issues; thanks to Fujitsu for the patch.
- Fixed the default hostfile MCA parameter behavior.
- Per the MPI spec, ensure not to touch the port_name parameter to
MPI_CLOSE_PORT (it's an IN parameter).
instead of "tcsh". This builds ok for me on NetBSD; if it turns out to
cause trouble for anyone, revert it.
The motivation was that the BUILD_DEPENDS accepted either tcsh or
standalone-tcsh, and distbb was latching onto the latter and then
failing trying to install it. If the package turns out to really need
tcsh in some contexts, there are probably other ways to deal with this
issue.
Changes in 1.5.5
----------------
- Many, many portability configure/build fixes courtesy of Paul
Hargrove. Thanks, Paul!
- Fixed shared memory fault tolerance support compiler errors.
- Removed not-production-quality rshd and tmd PLM launchers.
- Minor updates to the Open MPI SRPM spec file.
- Fixed mpirun's --bind-to-socket option.
- A few MPI_THREAD_MULTIPLE fixes in the shared memory BTL.
- Upgrade the GNU Autotools used to bootstrap the 1.5/1.6 series to
all the latest versions at the time of this release.
- Categorically state in the README that if you're having a problem
with Open MPI with the Linux Intel 12.1 compilers, *upgrade your
Intel Compiler Suite to the latest patch version*, and the problems
will go away. :-)
- Fix the --without-memory-manager configure option.
- Fixes for Totalview/DDT MPI-capable debuggers.
- Update rsh/ssh support to properly handle the Mac OS X library path
(i.e., DYLD_LIBRARY_PATH).
- Make warning about shared memory backing files on a networked file
system be optional (i.e., can be disabled via MCA parameter).
- Several fixes to processor and memory affinity.
- Various shared memory infrastructure improvements.
- Various checkpoint/restart fixes.
- Fix MPI_IN_PLACE (and other MPI sentinel values) on OS X. Thanks to
Dave Goodell for providing the magic OS X gcc linker flags necessary.
- Various man page corrections and typo fixes. Thanks to Fujitsu for
the patch.
- Updated wrapper compiler man pages to list the various --showme
options that are available.
- Add PMI direct-launch support (e.g., "srun mpi_application" under
SLURM).
- Correctly compute the aligned address when packing the
datatype description. Thanks to Fujitsu for the patch.
- Fix MPI obscure corner case handling in packing MPI datatypes.
Thanks to Fujitsu for providing the patch.
- Workaround an Intel compiler v12.1.0 2011.6.233 vector optimization
bug.
- Output the MPI API in ompi_info output.
- Major VT update to 5.12.1.4.
- Rankfile 'P'hysical mapping is no longer available.
- Upgrade embedded Hardware Locality (hwloc) v1.3.2, plus some
post-1.3.2-release bug fixes. All processor and memory binding is
now done through hwloc. Woo hoo! Note that this fixes core binding
on AMD Opteron 6200 and 4200 series-based systems (sometimes known
as Interlagos, Valencia, or other Bulldozer-based chips).
- New MCA parameters to control process-wide memory binding policy:
hwloc_base_mem_alloc_policy, hwloc_base_mem_bind_failure_action (see
ompi_info --param hwloc base).
- Removed direct support for libnuma. Libnuma support may now be
picked up through hwloc.
- Added MPI_IN_PLACE support to MPI_EXSCAN.
- Various fixes for building on Windows, including MinGW support.
- Removed support for the OpenFabrics IBCM connection manager.
- Updated Chelsio T4 and Intel NE OpenFabrics default buffer settings.
- Increased the default RDMA CM timeout to 30 seconds.
- Issue a warning if both btl_tcp_if_include and btl_tcp_if_exclude
are specified.
- Many fixes to the Mellanox MXM transport.
Heavily based on Sun Grid Engine package (parallel/sge).
Open Grid Scheduler/Grid Engine is a free and open-source
batch-queuing system for distributed resource management.
OGS/GE is based on Sun Grid Engine, and maintained by the same
group of external (i.e. non-Sun) developers who started
contributing code to Sun Grid Engine since 2001.
The Portable Hardware Locality (hwloc) software package provides
a portable abstraction (across OS, versions, architectures, ...)
of the hierarchical topology of modern architectures, including
NUMA memory nodes, sockets, shared caches, cores and
simultaneous multithreading. It also gathers various system
attributes such as cache and memory information as well as the
locality of I/O devices such as network interfaces, InfiniBand
HCAs or GPUs. It primarily aims at helping applications with
gathering information about modern computing hardware so as to
exploit it accordingly and efficiently.
The Son of Grid Engine is a community project to continue Sun Grid Engine.

SLURM is an open-source resource manager designed for Linux
clusters of all sizes. It provides three key functions. First it
allocates exclusive and/or non-exclusive access to resources
(computer nodes) to users for some duration of time so they can
perform work. Second, it provides a framework for starting,
executing, and monitoring work (typically a parallel job) on a
set of allocated nodes. Finally, it arbitrates contention for
resources by managing a queue of pending work.
