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

Version 8.0.0e
--------------
Mostly build and security issues
* Bug fixes
* 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.
* Avoid using mktemp. (Probably not a significant problem.)
* Control core dumps under setuid etc. with SGE_ENABLE_COREDUMP.
(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.

- 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.

--mem_bind=map_mem/mask_mem options, broken in 2.6.2.
-- Restore default behavior of allocating cores to jobs on a cyclic basis
across the sockets unless SelectTypeParameters=CR_CORE_DEFAULT_DIST_BLOCK
or user specifies other distribution options.
-- Enforce JobRequeue configuration parameter on node failure. Previously
always requeued the job.
-- acct_gather_energy/ipmi - Add delay before retry on read error.
-- select/cons_res with GRES and multiple threads per core, fix possible
infinite loop.
-- proctrack/cgroup - Add cgroup create retry logic in case one step is
starting at the same time as another step is ending and the logic to create
and delete cgroups overlaps.
-- Improve setting of job wait "Reason" field.
-- Correct sbatch documentation and job_submit/pbs plugin "%j" is job ID,
not "%J" (which is job_id.step_id).
-- Improvements to sinfo performance, especially for large numbers of
partitions.

-- Add support for some new #PBS options in sbatch scripts and qsub wrapper:
-l accelerator=true|false (GPU use)
-l mpiprocs=# (processors per node)
-l naccelerators=# (GPU count)
-l select=# (node count)
-l ncpus=# (task count)
-v key=value (environment variable)
-W depend=opts (job dependencies, including "on" and "before" options)
-W umask=# (set job's umask)
-- Added qalter and qrerun commands to torque package.
-- Corrections to qstat logic: job CPU count and partition time format.
-- Add job_submit/pbs plugin to translate PBS job dependency options to the
extend possible (no support for PBS "before" options) and set some PBS
environment variables.
-- Add spank/pbs plugin to set a bunch of PBS environment variables.
-- Backported sh5util from master to 2.6 as there are some important
bugfixes and the new item extraction feature.

into the future.
-- Scontrol - Enable changing a job's stdout file.
-- Fix issues where memory or node count of a srun job is altered while the
srun is pending. The step creation would use the old values and possibly
hang srun since the step wouldn't be able to be created in the modified
allocation.
-- Add support for new SchedulerParameters value of "bf_max_job_part", the
maximum depth the backfill scheduler should go in any single partition.
-- acct_gather/infiniband plugin - Correct packets_in/out values.
-- BLUEGENE - Don't ignore a conn-type request from the user.

file as a fatal error.
-- Fixed for if hours are specified as 0 the time days-0:min specification
is not parsed correctly.
-- switch/nrt - Fix for memory leak.
-- Subtract the PMII_COMMANDLEN_SIZE in contribs/pmi2/pmi2_api.c to prevent
certain implementation of snprintf() to segfault.
* Changes in Slurm 2.6.2
========================
-- Fix issue with reconfig and GrpCPURunMins
-- Fix of wrong node/job state problem after reconfig
-- Allow users who are coordinators update their own limits in the accounts
they are coordinators over.
-- BackupController - Make sure we have a connection to the DBD first thing
to avoid it thinking we don't have a cluster name.
-- Correct value of min_nodes returned by loading job information to consider
the job's task count and maximum CPUs per node.
-- If running jobacct_gather/none fix issue on unpacking step completion.
-- Reservation with CoreCnt: Avoid possible invalid memory reference.
-- sjstat - Add man page when generating rpms.
-- Make sure GrpCPURunMins is added when creating a user, account or QOS with
sacctmgr.
-- Fix for invalid memory reference due to multiple free calls caused by
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.
-- Use MAXPATHLEN instead of the hardcoded value 1024 for maximum file path
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.
-- sacct - fix --name and --partition options when using
accounting_storage/filetxt.

-- PMI2 Updated the Makefile.am to build a versioned library.
-- 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 AcctGatherProfileType documentation in slurm.conf
-- 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.
-- PGSQL - Notes about Postgres functionality being removed in the next
version of Slurm.
-- MYSQL - fix issue when rolling up usage and events happened when a cluster
was down (slurmctld not running) during that time period.
-- 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.
-- Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
* Changes in Slurm 2.6.0
========================
-- Fix it so bluegene and serial systems don't get warnings over new NODEDATA
enum.
-- When a job is aborted send a message for any tasks that have completed.
-- Correction to memory per CPU calculation on system with threads and
allocating cores or sockets.
-- Requeue batch job if it's node reboots (used to abort the job).
-- Enlarge maximum size of srun's hostlist file.
-- IPMI - Fix first poll to get correct consumed_energy for a step.
-- Correction to job state recovery logic that could result in assert failure.
-- Record partial step accounting record if allocated nodes fail abnormally.
-- Accounting - fix issue where PrivateData=jobs or users could potentially
show information to users that had no associations on the system.
-- Make PrivateData in slurmdbd.conf case insensitive.
-- sacct/sstat - Add format option ConsumedEnergyRaw to print full energy
values.
* Changes in Slurm 2.6.0rc2
===========================
-- HDF5 - Fix issue with Ubuntu where HDF5 development headers are
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.

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.

--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".

the node tab and we didn't notice.
-- Accounting - Fix an invalid memory read when slurmctld sends data about
start job to slurmdbd.

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.

-- 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.

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.

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.

-- Fix checking if QOS limit MaxCPUMinsPJ is set along with DenyOnLimit to
deny the job instead of holding it.
-- Make sure on systems that use a different launcher than launch/slurm not
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.

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.

a reservation and automatically change the reservation when nodes are
added to or removed from the reservation. Based upon work by
Bill Brophy, Bull.

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.

-- 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.

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.

with a job running or trying to run on it.
-- Execute slurm_spank_job_epilog when there is no system Epilog configured.

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

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.
-- BLUEGENE - Fix deadlock issue when dealing with bad hardware if using
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)
-- BGQ - fix for deadlock where a block has error on it and all jobs
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 - Remove extra overhead if a large block has many cnode failures.
-- Priority/Multifactor - Fix issue with age factor when a job is estimated to
start in the future but is able to run now.
-- CRAY - update to work with ALPS 5.1
-- 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.
-- CRAY - Fix for sacct -N option to work correctly
-- CRAY - Update documentation to describe installation from rpm instead
or previous piecemeal method.
-- Fix sacct to work with QOS' that have previously been deleted.
-- Added all available limits to the output of sacctmgr list qos
* Changes in SLURM 2.4.2
========================
-- 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.
Changes since 1.7 from NEWS file:

* Miscellaneous minor build fixes.
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.
This release adds several performance features for the Hydra process manager, support for communicator-specific tuning of eager/rendezvous thresholds, and fixes several bugs present in 3.0.3. Please use this release instead of 3.0.3.
A new stable release of MPICH, 3.0.3, is now available for download. This release adds several performance features for MPI-RMA and fixes several bugs present in 3.0.2. Please use this release instead of 3.0.2.

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.

the next step in the allocation only uses part of the allocation it gets
the correct cnodes.
-- BGQ - Fix checking for IO on a block with new IBM driver V1R1M1 previous
function didn't always work correctly.
-- BGQ - Fix issue when a nodeboard goes down and you want to combine blocks
to make a larger small block and are running with sub-blocks.
-- BLUEGENE - Better logic for making small blocks around bad nodeboard/card.
-- BGQ - When using an old IBM driver cnodes that go into error because of
a job kill timeout aren't always reported to the system. This is now
handled by the runjob_mux plugin.
-- BGQ - Added information on how to setup the runjob_mux to run as SlurmUser.
-- Improve memory consumption on step layouts with high task count.
-- BGQ - quiter debug when the real time server comes back but there are
still messages we find when we poll but haven't given it back to the real
time yet.
-- BGQ - fix for if a request comes in smaller than the smallest block and
we must use a small block instead of a shared midplane block.
-- Fix issues on large jobs (>64k tasks) to have the correct counter type when
packing the step layout structure.
-- BGQ - fix issue where if a user was asking for tasks and ntasks-per-node
but not node count the node count is correctly figured out.
-- Move logic to always use the 1st alphanumeric node as the batch host for
batch jobs.
-- BLUEGENE - fix race condition where if a nodeboard/card goes down at the
same time a block is destroyed and that block just happens to be the
smallest overlapping block over the bad hardware.
-- Fix bug when querying accounting looking for a job node size.
-- BLUEGENE - fix possible race condition if cleaning up a block and the
removal of the job on the block failed.
-- BLUEGENE - fix issue if a cable was in an error state make it so we can
check if a block is still makable if the cable wasn't in error.
-- Put nodes names in alphabetic order in node table.
-- If preempted job should have a grace time and preempt mode is not cancel
but job is going to be canceled because it is interactive or other reason
it now receives the grace time.
-- BGQ - Modified documents to explain new plugin_flags needed in bg.properties
in order for the runjob_mux to run correctly.
-- BGQ - change linking from libslurm.o to libslurmhelper.la to avoid warning.
* Changes in SLURM 2.4.0.rc1
=============================
-- Improve task binding logic by making fuller use of HWLOC library,
especially with respect to Opteron 6000 series processors. Work contributed
by Komoto Masahiro.
-- Add new configuration parameter PriorityFlags, based upon work by
Carles Fenoy (Barcelona Supercomputer Center).
-- Modify the step completion RPC between slurmd and slurmstepd in order to
eliminate a possible deadlock. Based on work by Matthieu Hautreux, CEA.
-- Change the owner of slurmctld and slurmdbd log files to the appropriate
user. Without this change the files will be created by and owned by the
user starting the daemons (likely user root).
-- Reorganize the slurmstepd logic in order to better support NFS and
Kerberos credentials via the AUKS plugin. Work by Matthieu Hautreux, CEA.
-- Fix bug in allocating GRES that are associated with specific CPUs. In some
cases the code allocated first available GRES to job instead of allocating
GRES accessible to the specific CPUs allocated to the job.
-- spank: Add callbacks in slurmd: slurm_spank_slurmd_{init,exit}
and job epilog/prolog: slurm_spank_job_{prolog,epilog}
-- spank: Add spank_option_getopt() function to api
-- Change resolution of switch wait time from minutes to seconds.
-- Added CrpCPUMins to the output of sshare -l for those using hard limit
accounting. Work contributed by Mark Nelson.
-- Added mpi/pmi2 plugin for complete support of pmi2 including acquiring
additional resources for newly launched tasks. Contributed by Hongjia Cao,
NUDT.
-- BGQ - fixed issue where if a user asked for a specific node count and more
tasks than possible without overcommit the request would be allowed on more
nodes than requested.
-- Add support for new SchedulerParameters of bf_max_job_user, maximum number
of jobs to attempt backfilling per user. Work by BjæËrn-Helge Mevik,
University of Oslo.
-- BLUEGENE - fixed issue where MaxNodes limit on a partition only limited
larger than midplane jobs.
-- Added cpu_run_min to the output of sshare --long. Work contributed by
Mark Nelson.
-- BGQ - allow regular users to resolve Rack-Midplane to AXYZ coords.
-- Add sinfo output format option of "%R" for partition name without "*"
appended for default partition.
-- Cray - Add support for zero compute note resource allocation to run batch
script on front-end node with no ALPS reservation. Useful for pre- or post-
processing.
-- Support for cyclic distribution of cpus in task/cgroup plugin from Martin
Perry, Bull.
-- GrpMEM limit for QOSes and associations added Patch from BjæËrn-Helge Mevik,
University of Oslo.
-- Various performance improvements for up to 500% higher throughput depending
upon configuration. Work supported by the Oak Ridge National Laboratory
Extreme Scale Systems Center.
-- Added jobacct_gather/cgroup plugin. It is not advised to use this in
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.

Intel(r) Threading Building Blocks (Intel TBB) offers a rich and
complete approach to expressing parallelism in a C++ program.
It is a library that helps you take advantage of multi-core
processor performance without having to be a threading expert.
Intel TBB is not just a threads-replacement library. It represents
a higher-level, task-based parallelism that abstracts platform
details and threading mechanisms for scalability and performance.

Changes in 1.3
# OVERALL: Initial support for fine-grained threading in
ch3:nemesis:tcp.
# OVERALL: Support for Asynchronous Communication Progress.
# OVERALL: The ssm and shm channels have been removed.
# OVERALL: Checkpoint/restart support using BLCR.
# OVERALL: Improved tolerance to process and communication failures
when error handler is set to MPI_ERRORS_RETURN. If a communication
operation fails (e.g., due to a process failure) MPICH2 will return
an error, and further communication to that process is not
possible. However, communication with other processes will still
proceed normally. Note, however, that the behavior collective
operations on communicators containing the failed process is
undefined, and may give incorrect results or hang some processes.
# OVERALL: Experimental support for inter-library dependencies.
# PM/PMI: Hydra is now the default process management framework
replacing MPD.
# PM/PMI: Added dynamic process support for Hydra.
# PM/PMI: Added support for LSF, SGE and POE in Hydra.
# PM/PMI: Added support for CPU and memory/cache topology aware
process-core binding.
# DEBUGGER: Improved support and bug fixes in the Totalview support.
# Build system: Replaced F90/F90FLAGS by FC/FCFLAGS. F90/F90FLAGS are
not longer supported in the configure.
# Multi-compiler support: On systems where C compiler that is used to
build mpich2 libraries supports multiple weak symbols and multiple aliases,
the Fortran binding built in the mpich2 libraries can handle different
Fortran compilers (than the one used to build mpich2). Details in README.
# Several other minor bug fixes, memory leak fixes, and code cleanup.

README file for more details.
- Added "fca" collective component, enabling MPI collective offload
support for Voltaire switches.
- Fixed MPI one-sided operations with large target displacements.
Thanks to Brian Price and Jed Brown for reporting the issue.

overrides supplying an _exclude list).
- Apply more scalable reachability algorithm on platforms with more
than 8 TCP interfaces.
- Various assembly code updates for more modern platforms / compilers.

ompi-f77, ompi-f90. See the README for more details.
- Removed the libopenmpi_malloc library (added in the v1.3 series)
since it is no longer necessary
- Add several notifier plugins (generally used when Open MPI detects
system/network administrator-worthy problems); each have their own
MCA parameters to govern their usage. See "ompi_info --param
notifier <name>" for more details.
- command to execute arbitrary commands (e.g., run a script).

I managed to trace things to the file libmetrics/netbsd/metrics.c in
the get_netbw function. Apparently, the code in get_netbw violates
alignment constraints for sparc64. I attached a patch against the result
of a "make patch" in parallel/ganglia-monitor-core. While I was at it, I
also changed proc_run_func somewhat to only count actually running
processes (having a look at NetBSD's ps(1) implementation) - without the
change, I got around 30 running processes on an idle machine.

New in OpenPA v1.0.2:
Major Changes:
* Add support for 64-bit PPC.

Grid Engine 6.2, which has undergone significant changes in qmaster to
significantly improve its scalability in challenging environments, adds
powerful features to the core system, introduces multi cluster support
for the Accounting and Reporting Console (ARCo) and comes with a new
module extending the scope of Grid Engine to a new domain of use cases:
the Service Domain Manager (SDM), aka. project Hedeby allows to
dynamically (re-)assign computational resources on demand.
plus lots of bug fixes.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
Changes since 1.0.7:
- Added support for MPI 2.1
- Added support for MPI_Type_create_resized and
MPI_Type_create_indexed_block datatypes in ROMIO.
- Bug fixes, memory leak fixes and code cleanup.

----------
2005-07-16 Ernst Rohlicek jun. <ernst.rohlicek@inode.at>
* Pvm.xs, Pvm.pm: Finished adding functionality of PVM v3.4 - siblings,
contexts and message boxes with their according new contants. All added
functionality tested.
Message handlers still missing. Testing routines for inclusion
in package still missing.
NOTE: Also created an ebuild (installation script) for the Gentoo
distribution.
MPICH2 is an all-new implementation of MPI from the group at Argonne
National Laboratory. It shares many goals with the original MPICH but
no actual code. It is a portable, high-performance implementation of
the entire MPI-2 standard. This release has all MPI-2 functions and
features required by the standard with the exception of support for the
"external32" portable I/O format.
Major enhancements:
A new program, dtop, allows the user to run top across multiple machines
and collate the results in real-time. The default remote commands have
been changed over to ssh from rsh. A test option has been added to all
commands to check if SSH is up and running before attempting an SSH
connection that might otherwise hang. A flag has been added to dsh
allowing the user to copy, execute, and delete a script on all machines
in one step. There are many other small bugfixes and enhancements.

the owner of all installed files is a non-root user. This change
affects most packages that require special users or groups by making
them use the specified unprivileged user and group instead.
(1) Add two new variables PKG_GROUPS_VARS and PKG_USERS_VARS to
unprivileged.mk. These two variables are lists of other bmake
variables that define package-specific users and groups. Packages
that have user-settable variables for users and groups, e.g. apache
and APACHE_{USER,GROUP}, courier-mta and COURIER_{USER,GROUP},
etc., should list these variables in PKG_USERS_VARS and PKG_GROUPS_VARS
so that unprivileged.mk can know to set them to ${UNPRIVILEGED_USER}
and ${UNPRIVILEGED_GROUP}.
(2) Modify packages to use PKG_GROUPS_VARS and PKG_USERS_VARS.
Update to 1.2.8 (formerly in devel/apr1), no longer build from the

variables so that the default INSTALL/DEINSTALL scripts from the
pkginstall framework do the right thing. Where possible, move some
post-install directions for package setup into MESSAGE files so that
they may be re-inspected by querying the installed package using
"pkg_info -D ...".
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
INSTALL/DEINSTALL script creation within pkgsrc.
If an INSTALL or DEINSTALL script is found in the package directory,
it is automatically used as a template for the pkginstall-generated
scripts. If instead, they should be used simply as the full scripts,
then the package Makefile should set INSTALL_SRC or DEINSTALL_SRC
explicitly, e.g.:
INSTALL_SRC= ${PKGDIR}/INSTALL
DEINSTALL_SRC= # emtpy
As part of the restructuring of the pkginstall framework internals,
we now *always* generate temporary INSTALL or DEINSTALL scripts. By
comparing these temporary scripts with minimal INSTALL/DEINSTALL
scripts formed from only the base templates, we determine whether or
not the INSTALL/DEINSTALL scripts are actually needed by the package
(see the generate-install-scripts target in bsd.pkginstall.mk).
In addition, more variables in the framework have been made private.
The *_EXTRA_TMPL variables have been renamed to *_TEMPLATE, which are
more sensible names given the very few exported variables in this
framework. The only public variables relating to the templates are:
INSTALL_SRC INSTALL_TEMPLATE
DEINSTALL_SRC DEINSTALL_TEMPLATE
HEADER_TEMPLATE
The packages in pkgsrc have been modified to reflect the changes in
the pkginstall framework.

Also convert REPLACE.*.new= ${SH:Q} back to ${SH}, as it should not be quoted
here, if at all.
Ok with rillig.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
Change pkg to use tk instead of tk83. I found no compelling reason for
it to still be dependant on the old version of tk.
Change the HOMEPAGE, as the old one no longer works.
Tested install, the pkg seems to install stuff properly now.. I believe
the PR should now be addressed fully.
