===========================================================================
|
|
|
|
This file contains the main features as well as overviews of specific
|
|
bug fixes (and other actions) for each version of Open MPI since
|
|
version 1.0.
|
|
|
|
As more fully described in the "Software Version Number" section in
|
|
the README file, Open MPI typically releases two separate version
|
|
series simultaneously. Since these series have different goals and
|
|
are semi-independent of each other, a single NEWS-worthy item may be
|
|
introduced into different series at different times. For example,
|
|
feature F was introduced in the vA.B series at version vA.B.C, and was
|
|
later introduced into the vX.Y series at vX.Y.Z.
|
|
|
|
The first time feature F is released, the item will be listed in the
|
|
vA.B.C section, denoted as:
|
|
|
|
(** also to appear: X.Y.Z) -- indicating that this item is also
|
|
likely to be included in future release
|
|
version vX.Y.Z.
|
|
|
|
When vX.Y.Z is later released, the same NEWS-worthy item will also be
|
|
included in the vX.Y.Z section and be denoted as:
|
|
|
|
(** also appeared: A.B.C) -- indicating that this item was previously
|
|
included in release version vA.B.C.
|
|
|

3.1.2 -- August, 2018
|
|
------------------------
|
|
|
|
- A subtle race condition bug was discovered in the "vader" BTL
|
|
(shared memory communications) that, in rare instances, can cause
|
|
MPI processes to crash or incorrectly classify (or effectively drop)
|
|
an MPI message sent via shared memory. If you are using the "ob1"
|
|
PML with "vader" for shared memory communication (note that vader is
|
|
the default for shared memory communication with ob1), you need to
|
|
upgrade to v3.1.2 or later to fix this issue. You may also upgrade
|
|
to the following versions to fix this issue:
|
|
- Open MPI v2.1.5 (expected end of August, 2018) or later in the
|
|
v2.1.x series
|
|
- Open MPI v3.0.1 (released March, 2018) or later in the v3.0.x
|
|
series
|
|
- Assorted Portals 4.0 bug fixes.
|
|
- Fix for possible data corruption in MPI_BSEND.
|
|
- Move shared memory file for vader btl into /dev/shm on Linux.
|
|
- Fix for MPI_ISCATTER/MPI_ISCATTERV Fortran interfaces with MPI_IN_PLACE.
|
|
- Upgrade PMIx to v2.1.3.
|
|
- Numerous One-sided bug fixes.
|
|
- Fix for race condition in uGNI BTL.
|
|
- Improve handling of large number of interfaces with TCP BTL.
|
|
- Numerous UCX bug fixes.
|
|
|
|
3.1.1 -- June, 2018
|
|
-------------------
|
|
|
|
- Fix potential hang in UCX PML during MPI_FINALIZE
|
|
- Update internal PMIx to v2.1.2rc2 to fix forward version compatibility.
|
|
- Add new MCA parameter osc_sm_backing_store to allow users to specify
|
|
where in the filesystem the backing file for the shared memory
|
|
one-sided component should live. Defaults to /dev/shm on Linux.
|
|
- Fix potential hang on non-x86 platforms when using builds with
|
|
optimization flags turned off.
|
|
- Disable osc/pt2pt when using MPI_THREAD_MULTIPLE due to numerous
|
|
race conditions in the component.
|
|
- Fix dummy variable names for the mpi and mpi_f08 Fortran bindings to
|
|
match the MPI standard. This may break applications which use
|
|
name-based parameters in Fortran which used our internal names
|
|
rather than those documented in the MPI standard.
|
|
- Revamp Java detection to properly handle new Java versions which do
|
|
not provide a javah wrapper.
|
|
- Fix RMA function signatures for use-mpi-f08 bindings to have the
|
|
asynchonous property on all buffers.
|
|
- Improved configure logic for finding the UCX library.
|
|
|
|
3.1.0 -- May, 2018
|
|
------------------
|
|
|
|

|
|
MPI_COMM_SPAWN_MULTIPLE.
|
|
- Fix bug with MODE_SEQUENTIAL and the sharedfp MPI-IO component.
|
|
- Use "javac -h" instead of "javah" when building the Java bindings
|
|
with a recent version of Java.
|
|
- Fix mis-handling of jostepid under SLURM that could cause problems
|
|
with PathScale/OmniPath NICs.
|
|
- Disable the POWER 7/BE block in configure. Note that POWER 7/BE is
|
|
still not a supported platform, but it is no longer automatically
|
|
disabled. See
|
|
https://github.com/open-mpi/ompi/issues/4349#issuecomment-374970982
|
|
for more information.
|
|
- The output-filename option for mpirun is now converted to an
|
|
absolute path before being passed to other nodes.
|
|
- Add monitoring component for PML, OSC, and COLL to track data
|
|
movement of MPI applications. See
|
|
ompi/mca/commmon/monitoring/HowTo_pml_monitoring.tex for more
|
|
information about the monitoring framework.
|
|
- Add support for communicator assertions: mpi_assert_no_any_tag,
|
|
mpi_assert_no_any_source, mpi_assert_exact_length, and
|
|
mpi_assert_allow_overtaking.
|
|
- Update PMIx to version 2.1.1.
|
|
- Update hwloc to 1.11.7.
|
|

|
|
- UCX PML improvements: add multi-threading support.
|
|
- Yalla PML improvements: Fix error with irregular contiguous datatypes.
|
|
- Openib BTL: disable XRC support by default.
|
|
- TCP BTL: Add check to detect and ignore connections from processes
|
|
that aren't MPI (such as IDS probes) and verify that source and
|
|
destination are using the same version of Open MPI, fix issue with very
|
|
large message transfer.
|
|
- ompi_info parsable output now escapes double quotes in values, and
|
|
also quotes values can contains colons. Thanks to Lev Givon for the
|
|
suggestion.
|
|
- CUDA-aware support can now handle GPUs within a node that do not
|
|
support CUDA IPC. Earlier versions would get error and abort.
|
|
- Add a mca parameter ras_base_launch_orted_on_hn to allow for launching
|
|
MPI processes on the same node where mpirun is executing using a separate
|
|
orte daemon, rather than the mpirun process. This may be useful to set to
|
|
true when using SLURM, as it improves interoperability with SLURM's signal
|
|
propagation tools. By default it is set to false, except for Cray XC systems.
|
|
- Remove LoadLeveler RAS support.
|
|
- Remove IB XRC support from the OpenIB BTL due to lack of support.
|
|
- Add functionality for IBM s390 platforms. Note that regular
|
|
regression testing does not occur on the s390 and it is not
|
|
considered a supported platform.
|
|
- Remove support for big endian PowerPC.
|
|
- Remove support for XL compilers older than v13.1.
|
|
- Remove support for atomic operations using MacOS atomics library.

|
|
- Fix segfault in the MTL/OFI initialization for large jobs.
|
|

|
|
|
3.0.5 -- November, 2019
|
|
-----------------------
|

|
Richard Warren for reporting the issue.
|
|
- At run time, automatically disable Linux cross-memory attach (CMA)
|
|
for vader BTL (shared memory) copies when running in user namespaces
|
|
(i.e., containers). Many thanks to Adrian Reber for raising the
|
|
issue and providing the fix.
|
|
- Sending very large MPI messages using the ofi MTL will fail with
|
|
some of the underlying Libfabric transports (e.g., PSM2 with
|
|
messages >=4GB, verbs with messages >=2GB). Prior version of Open
|
|
MPI failed silently; this version of Open MPI invokes the
|
|
appropriate MPI error handler upon failure. See
|
|
https://github.com/open-mpi/ompi/issues/7058 for more details.
|
|
Thanks to Emmanuel Thomé for raising the issue.
|
|

|
|
problematic platforms.
|
|
- Fix OMPIO offset calculations with SEEK_END and SEEK_CUR in
|
|
MPI_FILE_GET_POSITION. Thanks to Wei-keng Liao for raising the

|
|
Dickenson for raising the issue.
|
|
- Fix MPI buffered sends with the "cm" PML.
|
|

|
|
- Fix the Open MPI RPM spec file to not abort when grep fails. Thanks
|
|
to Daniel Letai for bringing this to our attention.
|
|

|
|
Open MPI was using). Thanks to Jordan Hayes for the report and the
|
|
initial fix.
|
|
- OMPI: fix division by zero with an empty file view.
|
|
- Also handle shmat()/shmdt() memory patching with OS-bypass networks.
|
|
- Add support for unwinding info to all files that are present in the
|
|
stack starting from MPI_Init, which is helpful with parallel
|
|
debuggers. Thanks to James Clark for the report and initial fix.
|
|
- Fixed inadvertant use of bitwise operators in the MPI C++ bindings
|
|
header files. Thanks to Bert Wesarg for the report and the fix.
|
|
- Added configure option --disable-wrappers-runpath (alongside the
|
|
already-existing --disable-wrappers-rpath option) to prevent Open
|
|
MPI's configure script from automatically adding runpath CLI options
|
|
to the wrapper compilers.
|
|
|

|
|
race conditions in the component.
|
|
- Fix dummy variable names for the mpi and mpi_f08 Fortran bindings to

for more information.
|
|
|
|
3.0.1 -- March, 2018
|
|
----------------------
|
|
|
|
- Fix ability to attach parallel debuggers to MPI processes.
|
|
- Fix a number of issues in MPI I/O found by the HDF5 test suite.
|
|
- Fix (extremely) large message transfers with shared memory.

|
|
reporting.
|
|
- Add UCX to list of interfaces that OpenSHMEM will use by default.
|
|
- Add --{enable|disable}-show-load-errors-by-default to control
|
|
default behavior of the load errors option.
|
|
- OFI MTL improvements: handle empty completion queues properly, fix

|
|
option for provider by default, Add support for reading multiple
|
|
CQ events in ofi_progress.
|
|
- PSM2 MTL improvements: Allow use of GPU buffers, thread fixes.
|
|
- Numerous corrections to memchecker behavior.
|
|
- Add a mca parameter ras_base_launch_orted_on_hn to allow for launching
|
|
MPI processes on the same node where mpirun is executing using a separate
|
|
orte daemon, rather than the mpirun process. This may be useful to set to
|
|
true when using SLURM, as it improves interoperability with SLURM's signal
|
|
propagation tools. By default it is set to false, except for Cray XC systems.
|
|
- Fix a problem reported on the mailing separately by Kevin McGrattan and Stephen
|
|
Guzik about consistency issues on NFS file systems when using OMPIO. This fix
|
|
also introduces a new mca parameter fs_ufs_lock_algorithm which allows to
|
|
control the locking algorithm used by ompio for read/write operations. By
|
|
default, ompio does not perfom locking on local UNIX file systems, locks the
|
|
entire file per operation on NFS file systems, and selective byte-range
|
|
locking on other distributed file systems.
|
|
- Add an mca parameter pmix_server_usock_connections to allow mpirun to
|

|
|
set to false by default.
|
|
|
|
3.0.0 -- September, 2017
|
|
------------------------
|
|
|
|
Major new features:
|
|
|
|
- Use UCX allocator for OSHMEM symmetric heap allocations to optimize intra-node
|
|
data transfers. UCX SPML only.
|
|
- Use UCX multi-threaded API in the UCX PML. Requires UCX 1.0 or later.
|
|
- Added support for Flux PMI
|
|
- Update embedded PMIx to version 2.1.0
|
|
- Update embedded hwloc to version 1.11.7
|
|
|
|
Changes in behavior compared to prior versions:
|
|
|
|
- Per Open MPI's versioning scheme (see the README), increasing the
|
|
major version number to 3 indicates that this version is not
|
|
ABI-compatible with prior versions of Open MPI. In addition, there may
|
|
be differences in MCA parameter names and defaults from previous releases.
|
|
Command line options for mpirun and other commands may also differ from
|
|
previous versions. You will need to recompile MPI and OpenSHMEM applications
|
|
to work with this version of Open MPI.
|
|
- With this release, Open MPI supports MPI_THREAD_MULTIPLE by default.
|
|
- New configure options have been added to specify the locations of libnl
|
|
and zlib.
|
|
- A new configure option has been added to request Flux PMI support.
|
|
- The help menu for mpirun and related commands is now context based.
|
|
"mpirun --help compatibility" generates the help menu in the same format
|
|
as previous releases.
|
|
|
|
Removed legacy support:
|
|
- AIX is no longer supported.
|
|
- Loadlever is no longer supported.
|
|
- OpenSHMEM currently supports the UCX and MXM transports via the ucx and ikrit
|
|
SPMLs respectively.
|
|
- Remove IB XRC support from the OpenIB BTL due to lack of support.
|
|
- Remove support for big endian PowerPC.
|
|
- Remove support for XL compilers older than v13.1
|
|
|
|
Known issues:
|
|
|
|
- MPI_Connect/accept between applications started by different mpirun
|
|
commands will fail, even if ompi-server is running.
|
|
|
|
2.1.5 -- August 2018
|
|
--------------------
|
|
|
|
- A subtle race condition bug was discovered in the "vader" BTL
|
|
(shared memory communications) that, in rare instances, can cause
|
|
MPI processes to crash or incorrectly classify (or effectively drop)
|
|
an MPI message sent via shared memory. If you are using the "ob1"
|
|
PML with "vader" for shared memory communication (note that vader is
|
|
the default for shared memory communication with ob1), you need to
|
|
upgrade to v2.1.5 to fix this issue. You may also upgrade to the
|
|
following versions to fix this issue:
|
|
- Open MPI v3.0.1 (released March, 2018) or later in the v3.0.x
|
|
series
|
|
- Open MPI v3.1.2 (expected end of August, 2018) or later
|
|
- A link issue was fixed when the UCX library was not located in the
|
|
linker-default search paths.
|
|
|
|

|
|
---------------------
|
|
|
|
Bug fixes/minor improvements:
|
|
- Disable the POWER 7/BE block in configure. Note that POWER 7/BE is
|
|
still not a supported platform, but it is no longer automatically
|
|
disabled. See
|
|
https://github.com/open-mpi/ompi/issues/4349#issuecomment-374970982
|
|
for more information.
|
|
- Fix bug with request-based one-sided MPI operations when using the
|
|
"rdma" component.

|
|
MPI_COMM_SPAWN_MULTIPLE (and its associated man page).
|
|
- Make NAG Fortran compiler support more robust in configure.
|
|
- Disable the "pt2pt" one-sided MPI component when MPI_THREAD_MULTIPLE
|
|
is used. This component is simply not safe in MPI_THREAD_MULTIPLE
|
|
scenarios, and will not be fixed in the v2.1.x series.
|
|
- Make the "external" hwloc component fail gracefully if it is tries
|
|
to use an hwloc v2.x.y installation. hwloc v2.x.y will not be
|
|
supported in the Open MPI v2.1.x series.
|
|
- Fix "vader" shared memory support for messages larger than 2GB.

|
|
|
|
2.1.0 -- March, 2017
|
|
--------------------
|
|
|
|
Major new features:
|
|
|
|
- The main focus of the Open MPI v2.1.0 release was to update to PMIx
|
|
v1.2.1. When using PMIx (e.g., via mpirun-based launches, or via
|
|
direct launches with recent versions of popular resource managers),
|
|
launch time scalability is improved, and the run time memory
|
|
footprint is greatly decreased when launching large numbers of MPI /
|
|
OpenSHMEM processes.
|
|
- Update OpenSHMEM API conformance to v1.3.
|
|
- The usnic BTL now supports MPI_THREAD_MULTIPLE.
|
|
- General/overall performance improvements to MPI_THREAD_MULTIPLE.
|
|
- Add a summary message at the bottom of configure that tells you many
|
|
of the configuration options specified and/or discovered by Open
|
|
MPI.
|
|
|
|
Changes in behavior compared to prior versions:
|
|
|
|
- None.
|
|
|
|
Removed legacy support:
|
|
|
|
- The ptmalloc2 hooks have been removed from the Open MPI code base.
|
|
This is not really a user-noticable change; it is only mentioned
|
|
here because there was much rejoycing in the Open MPI developer
|
|
community.
|
|
|
|
Bug fixes/minor improvements:
|
|
|
|
- New MCA parameters:
|
|
- iof_base_redirect_app_stderr_to_stdout: as its name implies, it
|
|
combines MPI / OpenSHMEM applications' stderr into its stdout
|
|
stream.
|
|
- opal_event_include: allow the user to specify which FD selection
|
|
mechanism is used by the underlying event engine.
|
|
- opal_stacktrace_output: indicate where stacktraces should be sent
|
|
upon MPI / OpenSHMEM process crashes ("none", "stdout", "stderr",
|
|
"file:filename").
|
|
- orte_timeout_for_stack_trace: number of seconds to wait for stack
|
|
traces to be reported (or <=0 to wait forever).
|
|
- mtl_ofi_control_prog_type/mtl_ofi_data_prog_type: specify libfabric
|
|
progress model to be used for control and data.
|
|
- Fix MPI_WTICK regression where the time reported may be inaccurate
|
|
on systems with processor frequency scalaing enabled.
|
|
- Fix regression that lowered the memory maximum message bandwidth for
|
|
large messages on some BTL network transports, such as openib, sm,
|
|
and vader.
|
|
- Fix a name collision in the shared file pointer MPI IO file locking
|
|
scheme. Thanks to Nicolas Joly for reporting the issue.
|
|
- Fix datatype extent/offset errors in MPI_PUT and MPI_RACCUMULATE
|
|
when using the Portals 4 one-sided component.
|
|
- Add support for non-contiguous datatypes to the Portals 4 one-sided
|
|
component.
|
|
- Various updates for the UCX PML.
|
|
- Updates to the following man pages:
|
|
- mpirun(1)
|
|
- MPI_COMM_CONNECT(3)
|
|
- MPI_WIN_GET_NAME(3). Thanks to Nicolas Joly for reporting the
|
|
typo.
|
|
- MPI_INFO_GET_[NKEYS|NTHKEY](3). Thanks to Nicolas Joly for
|
|
reporting the typo.
|
|
- Fixed a problem in the TCP BTL when using MPI_THREAD_MULTIPLE.
|
|
Thanks to Evgueni Petrov for reporting.
|
|
- Fixed external32 representation in the romio314 module. Note that
|
|
for now, external32 representation is not correctly supported by the
|
|
ompio module. Thanks to Thomas Gastine for bringing this to our
|
|
attention.
|
|
- Add note how to disable a warning message about when a high-speed
|
|
MPI transport is not found. Thanks to Susan Schwarz for reporting
|
|
the issue.
|
|
- Ensure that sending SIGINT when using the rsh/ssh launcher does not
|
|
orphan children nodes in the launch tree.
|
|
- Fix the help message when showing deprecated MCA param names to show
|
|
the correct (i.e., deprecated) name.
|
|
- Enable support for the openib BTL to use multiple different
|
|
InfiniBand subnets.
|
|
- Fix a minor error in MPI_AINT_DIFF.
|
|
- Fix bugs with MPI_IN_PLACE handling in:
|
|
- MPI_ALLGATHER[V]
|
|
- MPI_[I][GATHER|SCATTER][V]
|
|
- MPI_IREDUCE[_SCATTER]
|
|

- Add some deprecated names into shmem.h for backwards compatibility
|
|
with legacy codes.

|
|
- The vader BTL is now more efficient in terms of memory usage when
|
|
using XPMEM.
|
|
- Removed the --enable-openib-failover configure option. This is not
|
|
considered backwards-incompatible because this option was stale and

|
bindings. Thanks to Alastair McKinstry for the bug report.
|
|
- Add support for ARM v8.
|
|
- Several MCA parameters now directly support MPI_T enumerator
|
|
semantics (i.e., they accept a limited set of values -- e.g., MCA
|
|
parameters that accept boolean values).
|
|
- Added --with-libmpi-name=STRING configure option for vendor releases
|
|
of Open MPI. See the README for more detail.

2.0.0 -- 12 July 2016
|
|
---------------------
|
|
|
|
**********************************************************************
|
|
* Open MPI is now fully MPI-3.1 compliant
|
|
**********************************************************************
|
|
|
|
Major new features:
|
|
|
|
- Many enhancements to MPI RMA. Open MPI now maps MPI RMA operations
|
|
on to native RMA operations for those networks which support this
|
|
capability.
|
|
- Greatly improved support for MPI_THREAD_MULTIPLE (when configured
|
|
with --enable-mpi-thread-multiple).
|
|
- Enhancements to reduce the memory footprint for jobs at scale. A
|
|
new MCA parameter, "mpi_add_procs_cutoff", is available to set the
|
|
threshold for using this feature.
|
|
- Completely revamped support for memory registration hooks when using
|
|
OS-bypass network transports.
|
|
- Significant OMPIO performance improvements and many bug fixes.
|
|
- Add support for PMIx - Process Management Interface for Exascale.
|
|
Version 1.1.2 of PMIx is included internally in this release.
|
|
- Add support for PLFS file systems in Open MPI I/O.
|
|
- Add support for UCX transport.
|
|
- Simplify build process for Cray XC systems. Add support for
|
|
using native SLURM.
|
|
- Add a --tune mpirun command line option to simplify setting many
|
|
environment variables and MCA parameters.
|
|
- Add a new MCA parameter "orte_default_dash_host" to offer an analogue
|
|
to the existing "orte_default_hostfile" MCA parameter.
|
|
- Add the ability to specify the number of desired slots in the mpirun
|
|
--host option.
|
|
|
|
Changes in behavior compared to prior versions:
|
|
|
|
- In environments where mpirun cannot automatically determine the
|
|
number of slots available (e.g., when using a hostfile that does not
|
|
specify "slots", or when using --host without specifying a ":N"
|
|
suffix to hostnames), mpirun now requires the use of "-np N" to
|
|
specify how many MPI processes to launch.
|
|
- The MPI C++ bindings -- which were removed from the MPI standard in
|
|
v3.0 -- are no longer built by default and will be removed in some
|
|
future version of Open MPI. Use the --enable-mpi-cxx-bindings
|
|
configure option to build the deprecated/removed MPI C++ bindings.
|
|
- ompi_info now shows all components, even if they do not have MCA
|
|
parameters. The prettyprint output now separates groups with a
|
|
dashed line.
|
|
- OMPIO is now the default implementation of parallel I/O, with the
|
|
exception for Lustre parallel filesystems (where ROMIO is still the
|
|
default). The default selection of OMPI vs. ROMIO can be controlled
|
|
via the "--mca io ompi|romio" command line switch to mpirun.
|
|
- Per Open MPI's versioning scheme (see the README), increasing the
|
|
major version number to 2 indicates that this version is not
|
|
ABI-compatible with prior versions of Open MPI. You will need to
|
|
recompile MPI and OpenSHMEM applications to work with this version
|
|
of Open MPI.
|
|
- Removed checkpoint/restart code due to loss of maintainer. :-(
|
|
- Change the behavior for handling certain signals when using PSM and
|
|
PSM2 libraries. Previously, the PSM and PSM2 libraries would trap
|
|
certain signals in order to generate tracebacks. The mechanism was
|
|
found to cause issues with Open MPI's own error reporting mechanism.
|
|
If not already set, Open MPI now sets the IPATH_NO_BACKTRACE and
|
|
HFI_NO_BACKTRACE environment variables to disable PSM/PSM2's
|
|
handling these signals.
|
|
|
|
Removed legacy support:
|
|
|
|
- Removed support for OS X Leopard.
|
|
- Removed support for Cray XT systems.
|
|
- Removed VampirTrace.
|
|
- Removed support for Myrinet/MX.
|
|
- Removed legacy collective module:ML.
|
|
- Removed support for Alpha processors.
|
|
- Removed --enable-mpi-profiling configure option.

|
** the v1.8.x series, but with a few new features. v2.x will be the
|
|
** next series after the v1.10.x series, and complete the transition
|
|
** to the new version numbering scheme. See README for more details
|
|
** on the new versioning scheme.
|
|
**
|
|
** NOTE: In accordance with OMPI version numbering, the v1.10 is *not*
|
|
** API compatible with the v1.8 release series.

|
|
** have been, because the signatures were wrong :-)

1.7.4: 5 Feb 2014
|
|
-----------------
|
|
|
|
**********************************************************************
|
|
* CRITICAL CHANGE
|
|
*
|
|
* As of release 1.7.4, OpenMPI's default mapping, ranking, and binding
|
|
* settings have changed:
|
|
*
|
|
* Mapping:
|
|
* if #procs <= 2, default to map-by core
|
|
* if #procs > 2, default to map-by socket
|
|
* Ranking:
|
|
* if default mapping is used, then default to rank-by slot
|
|
* if map-by <obj> is given, then default to rank-by <obj>,
|
|
* where <obj> is whatever object we mapped against
|
|
* Binding:
|
|
* default to bind-to core
|
|
*
|
|
* Users can override any of these settings individually using the
|
|
* corresponding MCA parameter. Note that multi-threaded applications
|
|
* in particular may want to override at least the binding default
|
|
* to allow threads to use multiple cores.

|
|
release).
|
|
|
|
|
|
1.4: 8 Dec 2009
|
|
---------------
|
|
|
|
The *only* change in the Open MPI v1.4 release (as compared to v1.3.4)
|
|
was to update the embedded version of Libtool's libltdl to address a
|
|
potential security vulnerability. Specifically: Open MPI v1.3.4 was
|
|
created with GNU Libtool 2.2.6a; Open MPI v1.4 was created with GNU
|
|
Libtool 2.2.6b. There are no other changes between Open MPI v1.3.4
|
|
and v1.4.
|
|
|
|
|
|
1.3.4: 13 Feb 2010
|
|
------------------
|
|
|
|
- Fix some issues in OMPI's SRPM with regard to shell_scripts_basename
|
|
and its use with mpi-selector. Thanks to Bill Johnstone for
|
|
pointing out the problem.
|
|
- Added many new MPI job process affinity options to mpirun. See the
|
|
newly-updated mpirun(1) man page for details.
|
|
- Several updates to mpirun's XML output.
|
|
- Update to fix a few Valgrind warnings with regards to the ptmalloc2
|
|
allocator and Open MPI's use of PLPA.
|
|
- Many updates and fixes to the (non-default) "sm" collective
|
|
component (i.e., native shared memory MPI collective operations).
|
|
- Updates and fixes to some MPI_COMM_SPAWN_MULTIPLE corner cases.
|
|
- Fix some internal copying functions in Open MPI's use of PLPA.
|
|
- Correct some SLURM nodelist parsing logic that may have interfered
|
|
with large jobs. Additionally, per advice from the SLURM team,
|
|
change the environment variable that we use for obtaining the job's
|
|
allocation.
|
|
- Revert to an older, safer (but slower) communicator ID allocation
|
|
algorithm.
|
|
- Fixed minimum distance finding for OpenFabrics devices in the openib
|
|
BTL.
|
|
- Relax the parameter checking MPI_CART_CREATE a bit.
|
|
- Fix MPI_COMM_SPAWN[_MULTIPLE] to only error-check the info arguments
|
|
on the root process. Thanks to Federico Golfre Andreasi for
|
|
reporting the problem.
|
|
- Fixed some BLCR configure issues.
|
|
- Fixed a potential deadlock when the openib BTL was used with
|
|
MPI_THREAD_MULTIPLE.
|
|
- Fixed dynamic rules selection for the "tuned" coll component.
|
|
- Added a launch progress meter to mpirun (useful for large jobs; set
|
|
the orte_report_launch_progress MCA parameter to 1 to see it).
|
|
- Reduced the number of file descriptors consumed by each MPI process.
|
|
- Add new device IDs for Chelsio T3 RNICs to the openib BTL config file.
|
|
- Fix some CRS self component issues.
|
|
- Added some MCA parameters to the PSM MTL to tune its run-time
|
|
behavior.
|
|

|
|
- Man page updates from the Debain Open MPI package maintainers.
|
|
- Add cycle counter support for the Alpha and Sparc platforms.
|
|
- Pass visibility flags to libltdl's configure script, resulting in
|
|
those symbols being hidden. This appears to mainly solve the
|
|
problem of applications attempting to use different versions of
|
|
libltdl from that used to build Open MPI.
|
|
|
|
|
|
1.3.3: 14 Jul 2009

|
|
|
|
- Fix a number of issues with the openib BTL (OpenFabrics) RDMA CM,
|
|
including a memory corruption bug, a shutdown deadlock, and a route

timeout. Thanks to David McMillen and Hal Rosenstock for help in
|
|
tracking down the issues.
|
|
- Change the behavior of the EXTRA_STATE parameter that is passed to
|
|
Fortran attribute callback functions: this value is now stored
|
|
internally in MPI -- it no longer references the original value
|
|
passed by MPI_*_CREATE_KEYVAL.
|
|
- Allow the overriding RFC1918 and RFC3330 for the specification of
|
|
"private" networks, thereby influencing Open MPI's TCP
|
|
"reachability" computations.
|
|
- Improve flow control issues in the sm btl, by both tweaking the
|
|
shared memory progression rules and by enabling the "sync" collective
|
|
to barrier every 1,000th collective.
|
|
- Various fixes for the IBM XL C/C++ v10.1 compiler.
|
|
- Allow explicit disabling of ptmalloc2 hooks at runtime (e.g., enable

|
|
various Open MPI users for help with these issues.
|
|
- Miscellaneous VampirTrace fixes.
|

|
|
(add "send immediate" support to the openib BTL).
|
|
- Ensure to allow MPI_REQUEST_GET_STATUS to accept an
|
|
MPI_STATUS_IGNORE parameter. Thanks to Shaun Jackman for the bug
|
|
report.
|
|
- Added Microsoft Windows support. See README.WINDOWS file for
|
|
details.
|
|
|
|
|
|
1.3.2: 22 Apr 2009
|
|
------------------
|
|
|
|
- Fixed a potential infinite loop in the openib BTL that could occur
|
|
in senders in some frequent-communication scenarios. Thanks to Don
|
|
Wood for reporting the problem.
|
|
- Add a new checksum PML variation on ob1 (main MPI point-to-point
|
|
communication engine) to detect memory corruption in node-to-node
|
|
messages
|
|
- Add a new configuration option to add padding to the openib
|
|
header so the data is aligned
|
|
- Add a new configuration option to use an alternative checksum algo
|
|
when using the checksum PML
|
|
- Fixed a problem reported by multiple users on the mailing list that
|
|
the LSF support would fail to find the appropriate libraries at
|
|
run-time.

|
|
Koposov for the bug report.
|
|
- Ensure that mpirun exits with non-zero status when applications die
|
|
due to user signal. Thanks to Geoffroy Pignot for suggesting the
|
|
fix.
|
|
- Ensure that MPI_VERSION / MPI_SUBVERSION match what is returned by
|
|
MPI_GET_VERSION. Thanks to Rob Egan for reporting the error.
|
|
- Updated MPI_*KEYVAL_CREATE functions to properly handle Fortran
|
|
extra state.
|
|
- A variety of ob1 (main MPI point-to-point communication engine) bug
|
|
fixes that could have caused hangs or seg faults.
|
|
- Do not install Open MPI's signal handlers in MPI_INIT if there are
|
|
already signal handlers installed. Thanks to Kees Verstoep for
|
|
bringing the issue to our attention.
|
|
- Fix GM support to not seg fault in MPI_INIT.
|
|
- Various VampirTrace fixes.
|
|
- Various PLPA fixes.
|
|
- No longer create BTLs for invalid (TCP) devices.
|
|
- Various man page style and lint cleanups.
|
|
- Fix critical OpenFabrics-related bug noted here:
|
|
http://www.open-mpi.org/community/lists/announce/2009/03/0029.php.
|
|
Open MPI now uses a much more robust memory intercept scheme that is
|
|
quite similar to what is used by MX. The use of "-lopenmpi-malloc"
|
|
is no longer necessary, is deprecated, and is expected to disappear
|
|
in a future release. -lopenmpi-malloc will continue to work for the
|
|
duration of the Open MPI v1.3 and v1.4 series.
|
|
- Fix some OpenFabrics shutdown errors, both regarding iWARP and SRQ.
|
|
- Allow the udapl BTL to work on Solaris platforms that support
|
|
relaxed PCI ordering.
|
|
- Fix problem where the mpirun would sometimes use rsh/ssh to launch on
|
|
the localhost (instead of simply forking).
|
|
- Minor SLURM stdin fixes.
|
|
- Fix to run properly under SGE jobs.
|
|
- Scalability and latency improvements for shared memory jobs: convert
|
|
to using one message queue instead of N queues.
|
|
- Automatically size the shared-memory area (mmap file) to match
|
|
better what is needed; specifically, so that large-np jobs will start.
|
|
- Use fixed-length MPI predefined handles in order to provide ABI
|
|
compatibility between Open MPI releases.
|
|
- Fix building of the posix paffinity component to properly get the
|
|
number of processors in loosely tested environments (e.g.,
|
|
FreeBSD). Thanks to Steve Kargl for reporting the issue.
|
|
- Fix --with-libnuma handling in configure. Thanks to Gus Correa for
|
|
reporting the problem.
|
|
|
|
|
|
1.3.1: 19 Mar 2009
|
|
------------------
|
|
|
|
- Added "sync" coll component to allow users to synchronize every N
|
|
collective operations on a given communicator.
|
|
- Increased the default values of the IB and RNR timeout MCA parameters.
|
|
- Fix a compiler error noted by Mostyn Lewis with the PGI 8.0 compiler.
|
|
- Fix an error that prevented stdin from being forwarded if the
|
|
rsh launcher was in use. Thanks to Branden Moore for pointing out
|
|
the problem.
|
|
- Correct a case where the added datatype is considered as contiguous but
|
|
has gaps in the beginning.
|
|
- Fix an error that limited the number of comm_spawns that could
|
|
simultaneously be running in some environments
|
|
- Correct a corner case in OB1's GET protocol for long messages; the
|
|
error could sometimes cause MPI jobs using the openib BTL to hang.
|
|
- Fix a bunch of bugs in the IO forwarding (IOF) subsystem and add some
|
|
new options to output to files and redirect output to xterm. Thanks to
|
|
Jody Weissmann for helping test out many of the new fixes and
|
|
features.
|
|
- Fix SLURM race condition.
|
|
- Fix MPI_File_c2f(MPI_FILE_NULL) to return 0, not -1. Thanks to
|
|
Lisandro Dalcín for the bug report.
|
|
- Fix the DSO build of tm PLM.
|
|
- Various fixes for size disparity between C int's and Fortran
|
|
INTEGER's. Thanks to Christoph van Wullen for the bug report.
|
|
- Ensure that mpirun exits with a non-zero exit status when daemons or
|
|
processes abort or fail to launch.
|
|
- Various fixes to work around Intel (NetEffect) RNIC behavior.
|
|
- Various fixes for mpirun's --preload-files and --preload-binary
|
|
options.
|
|
- Fix the string name in MPI::ERRORS_THROW_EXCEPTIONS.
|
|
- Add ability to forward SIFTSTP and SIGCONT to MPI processes if you
|
|
set the MCA parameter orte_forward_job_control to 1.
|
|
- Allow the sm BTL to allocate larger amounts of shared memory if
|
|
desired (helpful for very large multi-core boxen).
|
|
- Fix a few places where we used PATH_MAX instead of OPAL_PATH_MAX,
|
|
leading to compile problems on some platforms. Thanks to Andrea Iob
|
|
for the bug report.
|
|
- Fix mca_btl_openib_warn_no_device_params_found MCA parameter; it
|
|
was accidentally being ignored.
|
|
- Fix some run-time issues with the sctp BTL.
|
|
- Ensure that RTLD_NEXT exists before trying to use it (e.g., it
|
|
doesn't exist on Cygwin). Thanks to Gustavo Seabra for reporting
|
|
the issue.
|
|
- Various fixes to VampirTrace, including fixing compile errors on
|
|
some platforms.
|
|
- Fixed missing MPI_Comm_accept.3 man page; fixed minor issue in
|
|
orterun.1 man page. Thanks to Dirk Eddelbuettel for identifying the
|
|
problem and submitting a patch.
|
|
- Implement the XML formatted output of stdout/stderr/stddiag.
|
|
- Fixed mpirun's -wdir switch to ensure that working directories for
|
|
multiple app contexts are properly handled. Thanks to Geoffroy
|
|
Pignot for reporting the problem.

|
|
- Allow MPI::SEEK_* constants to be used as constants
|
|
- Allow other MPI C++ constants to be used as array sizes
|
|
- Fix minor problem with orte-restart's command line options. See
|
|
ticket #1761 for details. Thanks to Gregor Dschung for reporting
|
|
the problem.
|
|
|
|
|
|
1.3: 19 Jan 2009
|
|
----------------
|
|
|
|
- Extended the OS X 10.5.x (Leopard) workaround for a problem when
|
|
assembly code is compiled with -g[0-9]. Thanks to Barry Smith for
|
|
reporting the problem. See ticket #1701.
|
|
- Disabled MPI_REAL16 and MPI_COMPLEX32 support on platforms where the
|
|
bit representation of REAL*16 is different than that of the C type
|
|
of the same size (usually long double). Thanks to Julien Devriendt
|
|
for reporting the issue. See ticket #1603.
|
|
- Increased the size of MPI_MAX_PORT_NAME to 1024 from 36. See ticket #1533.
|
|
- Added "notify debugger on abort" feature. See tickets #1509 and #1510.
|
|
Thanks to Seppo Sahrakropi for the bug report.
|
|
- Upgraded Open MPI tarballs to use Autoconf 2.63, Automake 1.10.1,
|
|
Libtool 2.2.6a.
|
|
- Added missing MPI::Comm::Call_errhandler() function. Thanks to Dave
|
|
Goodell for bringing this to our attention.
|
|
- Increased MPI_SUBVERSION value in mpi.h to 1 (i.e., MPI 2.1).
|
|
- Changed behavior of MPI_GRAPH_CREATE, MPI_TOPO_CREATE, and several
|
|
other topology functions per MPI-2.1.
|
|
- Fix the type of the C++ constant MPI::IN_PLACE.
|
|
- Various enhancements to the openib BTL:
|
|
- Added btl_openib_if_[in|ex]clude MCA parameters for
|
|
including/excluding comma-delimited lists of HCAs and ports.
|
|
- Added RDMA CM support, includng btl_openib_cpc_[in|ex]clude MCA
|
|
parameters
|
|
- Added NUMA support to only use "near" network adapters
|
|
- Added "Bucket SRQ" (BSRQ) support to better utilize registered
|
|
memory, including btl_openib_receive_queues MCA parameter
|
|
- Added ConnectX XRC support (and integrated with BSRQ)
|
|
- Added btl_openib_ib_max_inline_data MCA parameter
|
|
- Added iWARP support
|
|
- Revamped flow control mechansisms to be more efficient
|
|
- "mpi_leave_pinned=1" is now the default when possible,
|
|
automatically improving performance for large messages when
|
|
application buffers are re-used
|
|
- Elimiated duplicated error messages when multiple MPI processes fail
|
|
with the same error.
|
|
- Added NUMA support to the shared memory BTL.
|
|
- Add Valgrind-based memory checking for MPI-semantic checks.
|
|
- Add support for some optional Fortran datatypes (MPI_LOGICAL1,
|
|
MPI_LOGICAL2, MPI_LOGICAL4 and MPI_LOGICAL8).
|
|
- Remove the use of the STL from the C++ bindings.
|
|
- Added support for Platform/LSF job launchers. Must be Platform LSF
|
|
v7.0.2 or later.
|
|
- Updated ROMIO with the version from MPICH2 1.0.7.
|
|
- Added RDMA capable one-sided component (called rdma), which
|
|
can be used with BTL components that expose a full one-sided
|
|
interface.
|
|
- Added the optional datatype MPI_REAL2. As this is added to the "end of"
|
|
predefined datatypes in the fortran header files, there will not be
|
|
any compatibility issues.
|
|
- Added Portable Linux Processor Affinity (PLPA) for Linux.
|
|
- Addition of a finer symbols export control via the visibiliy feature
|
|
offered by some compilers.
|
|
- Added checkpoint/restart process fault tolerance support. Initially
|
|
support a LAM/MPI-like protocol.
|
|
- Removed "mvapi" BTL; all InfiniBand support now uses the OpenFabrics
|
|
driver stacks ("openib" BTL).
|
|
- Added more stringent MPI API parameter checking to help user-level
|
|
debugging.
|
|
- The ptmalloc2 memory manager component is now by default built as
|
|
a standalone library named libopenmpi-malloc. Users wanting to
|
|
use leave_pinned with ptmalloc2 will now need to link the library
|
|
into their application explicitly. All other users will use the
|
|
libc-provided allocator instead of Open MPI's ptmalloc2. This change
|
|
may be overriden with the configure option enable-ptmalloc2-internal
|
|
- The leave_pinned options will now default to using mallopt on
|
|
Linux in the cases where ptmalloc2 was not linked in. mallopt
|
|
will also only be available if munmap can be intercepted (the
|
|
default whenever Open MPI is not compiled with --without-memory-
|
|
manager.
|
|
- Open MPI will now complain and refuse to use leave_pinned if
|
|
no memory intercept / mallopt option is available.
|
|
- Add option of using Perl-based wrapper compilers instead of the
|
|
C-based wrapper compilers. The Perl-based version does not
|
|
have the features of the C-based version, but does work better
|
|
in cross-compile environments.
|
|
|
|

|
|
|
|
1.2.3: 20 Jun 2007
|
|
------------------
|
|
|
|
- Fix a regression in comm_spawn functionality that inadvertently

|
- Fixed race condition in the shared memory fifo's, which led to
|
|
orphaned messages.
|
|
- Corrected the size of the shared memory file - subtracted out the
|
|
space the header was occupying.
|
|
- Add support for MPI_2COMPLEX and MPI_2DOUBLE_COMPLEX.
|
|
- Always ensure to create $(includedir)/openmpi, even if the C++
|
|
bindings are disabled so that the wrapper compilers don't point to
|
|
a directory that doesn't exist. Thanks to Martin Audet for
|
|
identifying the problem.
|
|
- Fixes for endian handling in MPI process startup.
|
|
- Openib BTL initialization fixes for cases where MPI processes in the
|
|
same job has different numbers of active ports on the same physical
|
|
fabric.

|
OS's that support this functionality, such as the hostname and PID
|
|
of the process in question.
|
|
- Fixes to properly handle MPI exceptions in C++ on communicators,
|
|
windows, and files.
|
|
- Much more reliable runtime support, particularly with regards to MPI
|
|
job startup scalability, BProc support, and cleanup in failure
|

|
|
particularly on high-speed networks.

|
|
memory for OpenFabrics and GM.
|
|
- Users who utilize the wrapper compilers (e.g., mpicc and mpif77)
|
|
will not notice, but the underlying library names for ORTE and OPAL
|
|
have changed to libopen-rte and libopen-pal, respectively (listed
|
|
here because there are undoubtedly some users who are not using the
|
|
wrapper compilers).
|
|
- Many bug fixes to MPI-2 one-sided support.
|
|
- Added support for TotalView message queue debugging.
|
|

|
|
functions to be profiled properly.
|
|
- Add new --enable-mpirun-prefix-by-default configure option to always
|
|
imply the --prefix option to mpirun, preventing many rsh/ssh-based
|
|
users from needing to modify their shell startup files.
|
|
- Add a number of missing constants in the C++ bindings.
|
|
- Added tight integration with Sun N1 Grid Engine (N1GE) 6 and the
|
|
open source Grid Engine.
|
|
- Allow building the F90 MPI bindings as shared libraries for most
|
|
compilers / platforms. Explicitly disallow building the F90
|
|
bindings as shared libraries on OS X because of complicated
|
|
situations with Fortran common blocks and lack of support for
|
|
unresolved common symbols in shared libraries.
|
|
- Added stacktrace support for Solaris and Mac OS X.
|
|
- Update event library to libevent-1.1b.
|

|
|
interconnects, with support for Myrinet/MX, and QLogic PSM-based
|
|
networks.
|
|
- Addition of "udapl" BTL for transport across uDAPL interconnects.
|
|
- Really check that the $CXX given to configure is a C++ compiler
|
|
(not a C compiler that "sorta works" as a C++ compiler).
|
|
- Properly check for local host only addresses properly, looking
|
|
for 127.0.0.0/8, rather than just 127.0.0.1.
|
|
|
|
|
|
1.1.5: 19 Mar 2007
|
|
------------------
|
|
|

|
|
Bert Wesarg for pointing this out.
|
|
- Add new MCA parameter (mpi_preconnect_oob) for pre-connecting the
|
|
"out of band" channels between all MPI processes. Most helpful for
|
|
MPI applications over InfiniBand where process A sends an initial
|
|
message to process B, but process B does not enter the MPI library
|
|
for a long time.
|
|
- Fix for a race condition in shared memory locking semantics.
|
|
- Add major, minor, and release version number of Open MPI to mpi.h.

|
------------------
|
|
|
|

|
|
intel-based OS X machines.
|
|
- Adjusted TCP interface selection to automatically ignore Linux
|
|
channel-bonded slave interfaces.
|
|
- Fixed the type of the first parameter to the MPI F90 binding for
|
|
MPI_INITIALIZED. Thanks to Tim Campbell for pointing out the
|
|
problem.
|
|
- Fix a bunch of places in the Fortran MPI bindings where (MPI_Fint*)
|
|
was mistakenly being used instead of (MPI_Aint*).
|
|
- Fixes for fortran MPI_STARTALL, which could sometimes return
|
|
incorrect request values. Thanks to Tim Campbell for pointing out
|

at Sandia National Laboratories and Martin Schaffoner for access to
|
|
testing facilities to make this happen.
|
|
- Added new command line options to mpirun:
|
|
--nolocal: Do not run any MPI processes on the same node as mpirun
|
|
(compatibility with the OSC mpiexec launcher)
|
|

|
1.1: 23 Jun 2006
|
|
----------------
|
|
|
|
- Various MPI datatype fixes, optimizations.
|
|
- Fixed various problems on the SPARC architecture (e.g., not
|
|
correctly aligning addresses within structs).
|
|
- Improvements in various run-time error messages to be more clear
|
|
about what they mean and where the errors are occurring.
|
|
- Various fixes to mpirun's handling of --prefix.
|
|
- Updates and fixes for Cray/Red Storm support.
|
|
- Major improvements to the Fortran 90 MPI bindings:
|
|
- General improvements in compile/linking time and portability
|
|
between different F90 compilers.
|
|
- Addition of "trivial", "small" (the default), and "medium"
|
|
Fortran 90 MPI module sizes (v1.0.x's F90 module was
|
|
equivalent to "medium"). See the README file for more
|
|
explanation.
|
|
- Fix various MPI F90 interface functions and constant types to
|
|
match. Thanks to Michael Kluskens for pointing out the problems
|
|
to us.
|
|
- Allow short messagees to use RDMA (vs. send/receive semantics) to a
|
|
limited number peers in both the mvapi and openib BTL components.
|
|
This reduces communication latency over IB channels.
|
|
- Numerous performance improvements throughout the entire code base.
|
|
- Many minor threading fixes.
|
|
- Add a define OMPI_SKIP_CXX to allow the user to skip the mpicxx.h from
|
|
being included in mpi.h. It allows the user to compile C code with a CXX
|
|
compiler without including the CXX bindings.
|
|
- PERUSE support has been added. In order to activate it add
|
|
--enable-peruse to the configure options. All events described in
|
|
the PERUSE 2.0 draft are supported, plus one Open MPI
|
|
extension. PERUSE_COMM_REQ_XFER_CONTINUE allow to see how the data
|
|
is segmented internally, using multiple interfaces or the pipeline
|
|
engine. However, this version only support one event of each type
|
|
simultaneously attached to a communicator.
|
|
- Add support for running jobs in heterogeneous environments.
|
|
Currently supports environments with different endianness and
|
|
different representations of C++ bool and Fortran LOGICAL.
|
|
Mismatched sizes for other datatypes is not supported.
|
|
- Open MPI now includes an implementation of the MPI-2 One-Sided
|
|
Communications specification.
|
|
- Open MPI is now configurable in cross-compilation environments.
|
|
Several Fortran 77 and Fortran 90 tests need to be pre-seeded with
|
|
results from a config.cache-like file.
|
|
- Add --debug option to mpirun to generically invoke a parallel debugger.
|
|
|
|
|
|

- Added MPI_BOOL to the intrinsic reduction operations MPI_LAND,
|
|
MPI_LOR, MPI_LXOR. Thanks to Andy Selle for pointing this out to us.
|
|
- Fixed TCP BTL network matching logic during MPI_INIT; in some cases
|
|
on multi-NIC nodes, a NIC could get paired with a NIC on another
|
|
network (typically resulting in deadlock). Thanks to Ken Mighell
|
|
for pointing this out to us.
|
|
- Change the behavior of orterun (mpirun, mpirexec) to search for
|
|
argv[0] and the cwd on the target node (i.e., the node where the
|
|
executable will be running in all systems except BProc, where the
|
|
searches are run on the node where orterun is invoked).
|

|
|
- Change the exit status set by mpirun when an application process is
|
|
killed by a signal. The exit status is now set to signo + 128, which
|
|
conforms with the behavior of (almost) all shells.
|
|
- Correct a datatype problem with the convertor when partially
|
|
unpacking data. Now we can position the convertor to any position
|
|
not only on the predefined types boundaries. Thanks to Yvan Fournier
|
|
for reporting this to us.
|
|
- Fix a number of standard I/O forwarding issues, including the
|
|
ability to background mpirun and a loss of data issue when

redirecting mpirun's standard input from a file.
|
|
- Fixed bug in ompi_info where rcache and bml MCA parameters would not
|
|
be displayed.

|
|
Gottbrath for supplying the fix.
|
|
- Fix Darwin net/if.h configure warning.
|
|
- The GNU assembler unbelievably defaults to making stacks executable.
|
|
So when using gas, add flags to explicitly tell it to not make
|
|
stacks executable (lame but necessary).
|
|
- Add missing MPI::Request::Get_status() methods. Thanks to Bill
|
|
Saphir for pointing this out to us.
|
|
- Improved error messages on memory registration errors (e.g., when
|
|
using high-speed networks).
|
|
- Open IB support now checks firmware for how many outstanding RDMA
|
|
requests are supported. Thanks to Mellanox for pointing this out to
|
|
us.

|
|
problems.
|
|
- Properly handle the case where an mVAPI does not have shared receive
|
|
queue support (such as the one shipped by SilverStorm / Infinicon
|
|
for OS X).
|
|
|
|
|
|

|
- Converted MPI_Offset to be a typedef instead of a #define because it
|
|
causes problems for some C++ parsers. Thanks to Martin Audet for
