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.

* 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.

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.

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.

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 v1.5.4 as compared to v1.5.3:
- Add support for the (as yet unreleased) Mellanox MXM transport.
- Add support for dynamic service levels (SLs) in the openib BTL.
- Fixed C++ bindings cosmetic/warnings issue with
MPI::Comm::NULL_COPY_FN and MPI::Comm::NULL_DELETE_FN. Thanks to
Julio Hoffimann for identifying the issues.
- Also allow the word "slots" in rankfiles (i.e., not just "slot").
(** also to appear in 1.4.4)
- Add Mellanox ConnectX 3 device IDs to the openib BTL defaults.
(** also to appear in 1.4.4)
- Various FCA updates.
- Fix 32 bit SIGBUS errors on Solaris SPARC platforms.
- Add missing ARM assembly code files.
- Update to allow more than 128 entries in an appfile.
(** also to appear in 1.4.4)
- Various VT updates and bug fixes.
- Update description of btl_openib_cq_size to be more accurate.
(** also to appear in 1.4.4)
- Various assembly "clobber" fixes.
- Fix a hang in carto selection in obscure situations.
- Guard the inclusion of execinfo.h since not all platforms have it. Thanks
to Aleksej Saushev for identifying this issue.
(** also to appear in 1.4.4)
- Support Solaris legacy munmap prototype changes.
(** also to appear in 1.4.4)
- Updated to Automake 1.11.1 per
http://www.open-mpi.org/community/lists/devel/2011/07/9492.php.
- Fix compilation of LSF support.
- Update MPI_Comm_spawn_multiple.3 man page to reflect what it
actually does.
- Fix for possible corruption of the environment. Thanks to Peter
Thompson for the suggestion. (** also to appear in 1.4.4)
- Enable use of PSM on direct-launch SLURM jobs.
- Update paffinity hwloc to v1.2, and to fix minor bugs affinity
assignment bugs on PPC64/Linux platforms.
- Let the openib BTL auto-detect its bandwidth.
- Support new MPI-2.2 datatypes.
- Updates to support more datatypes in MPI one-sided communication.
- Fix recursive locking bug when MPI-IO was used with
MPI_THREAD_MULTIPLE. (** also to appear in 1.4.4)
- Fix mpirun handling of prefix conflicts.
- Ensure mpirun's --xterm options leaves sessions attached.
(** also to appear in 1.4.4)
- Fixed type of sendcounts and displs in the "use mpi" F90 module.
ABI is preserved, but applications may well be broken. See the
README for more details. Thanks to Stanislav Sazykin for
identifying the issue. (** also to appear in 1.4.4)
- Fix indexed datatype leaks. Thanks to Pascal Deveze for supplying
the initial patch. (** also to appear in 1.4.4)
- Fix debugger mapping when mpirun's -npernode option is used.
- Fixed support for configure's --disable-dlopen option when used with
"make distclean".
- Fix segv associated with MPI_Comm_create with MPI_GROUP_EMPTY.
Thanks to Dominik Goeddeke for finding this.
(** also to appear in 1.4.4)
- Improved LoadLeveler ORTE support.
- Add new WindVerbs BTL plugin, supporting native OpenFabrics verbs on
Windows (the "wv" BTL).
- Add new btl_openib_gid_index MCA parameter to allow selecting which
GID to use on an OpenFabrics device's GID table.
- Add support for PCI relaxed ordering in the OpenFabrics BTL (when
available).
- Update rsh logic to allow correct SGE operation.
- Ensure that the mca_paffinity_alone MCA parameter only appears once
in the ompi_info output. Thanks to Gus Correa for identifying the
issue.
- Fixed return codes from MPI_PROBE and MPI_IPROBE.
(** also to appear in 1.4.4)
- Remove --enable-progress-thread configure option; it doesn't work on
the v1.5 branch. Rename --enable-mpi-threads to
--enable-mpi-thread-multiple. Add new --enable-opal-multi-threads
option.
- Updates for Intel Fortran compiler version 12.
- Remove bproc support. Farewell bproc!
- If something goes wrong during MPI_INIT, fix the error
message to say that it's illegal to invoke MPI_INIT before
MPI_INIT.
