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.
mk-configure>=0.23.0 is required at build time

correctly when transitioning. This also applies for 2.4.0 -> 2.4.1, no
state will be lost. (Thanks to Carles Fenoy)
* Changes in SLURM 2.4.0
========================
-- Cray - Improve support for zero compute note resource allocations.
Partition used can now be configured with no nodes nodes.
-- BGQ - make it so srun -i<taskid> works correctly.
-- Fix parse_uint32/16 to complain if a non-digit is given.
-- Add SUBMITHOST to job state passed to Moab vial sched/wiki2. Patch by Jon
Bringhurst (LANL).
-- BGQ - Fix issue when running with AllowSubBlockAllocations=Yes without
compiling with --enable-debug
-- Modify scontrol to require "-dd" option to report batch job's script. Patch
from Don Albert, Bull.
-- Modify SchedulerParamters option to match documentation: "bf_res="
changed to "bf_resolution=". Patch from Rod Schultz, Bull.
-- Fix bug that clears job pending reason field. Patch fron Don Lipari, LLNL.
-- In etc/init.d/slurm move check for scontrol after sourcing
/etc/sysconfig/slurm. Patch from Andy Wettstein, University of Chicago.
-- Fix in scheduling logic that can delay jobs with min/max node counts.
-- BGQ - fix issue where if a step uses the entire allocation and then
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}

-- 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.

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.

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.

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.

support for rank prepending on output. Improvements to STDIN
handling for applications being run in the background.
# PM/PMI: Split the bootstrap servers into "launchers" and "resource
managers", allowing the user to pick a different resource manager
from the launcher. For example, the user can now pick the "SLURM"
resource manager and "SSH" as the launcher.
# PM/PMI: The MPD process manager is deprecated.
# PM/PMI: The PLPA process binding library support is deprecated.
# WINDOWS: Adding support for gfortran and 64-bit gcc libs.
# Several other minor bug fixes, memory leak fixes, and code cleanup.

parallel/threadingbuildingblocks.
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.

- 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.
