===========================================================================
|
|
|
|
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.
|
|
|
|
Trunk (not on release branches yet)
|
|
-----------------------------------
|
|
|
|
- Add pkg-config(1) configuration files for ompi, ompi-c, ompi-cxx,
|
|
ompi-f77, ompi-f90. See the README for more details.
|
|
|
|
|
|
1.5
|
|
---
|
|
|
|
- Updated shared library versioning scheme and linking style of MPI
|
|
applications. ABI has been broken from the v1.4 series; see the
|
|
README file for more details.
|
|
- Added "knem" support (direct process-to-process copying for shared
|
|
memory message passing). See http://runtime.bordeaux.inria.fr/knem/
|
|
and the README file 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.
|
|
- twitter (yes, that Twitter) to send a Tweet.
|
|
- smtp (requires libesmtp) to send an email.
|
|
- command to execute arbitrary commands (e.g., run a script).
|
|
|
|
|
|
1.4.2 (expected)
|
|
----------------
|
|
|
|
- Fixed "mpirun --report-bindings" behavior when used with
|
|
mpi_paffinity_alone=1. Also fixed mpi_paffinity_alone=1 behavior
|
|
with non-MPI applications. Thanks to Brice Goglin for noticing the
|
|
problem.
|
|
- Removed flex.exe binary from Open MPI tarballs; now generate flex
|
|
code from a newer (Windows-friendly) flex when we make official
|
|
tarballs.
|
|
|
|
|
|
1.4.1
|
|
-----
|
|
|
|
- Update to PLPA v1.3.2, addressing a licensing issue identified by
|
|
the Fedora project. See
|
|
https://svn.open-mpi.org/trac/plpa/changeset/262 for details.
|
|
- Add check for malformed checkpoint metadata files (Ticket #2141).
|
|
- Fix error path in ompi-checkpoint when not able to checkpoint
|
|
(Ticket #2138).
|
|
- Cleanup component release logic when selecting checkpoint/restart
|
|
enabled components (Ticket #2135).
|
|
- Fixed VT node name detection for Cray XT platforms, and fixed some
|
|
broken VT documentation files.
|
|
- Fix a possible race condition in tearing down RDMA CM-based
|
|
connections.
|
|
- Relax error checking on MPI_GRAPH_CREATE. Thanks to David Singleton
|
|
for pointing out the issue.
|
|
- Fix a shared memory "hang" problem that occurred on x86/x86_64
|
|
platforms when used with the GNU >=4.4.x compiler series.
|
|
- Add fix for Libtool 2.2.6b's problems with the PGI 10.x compiler
|
|
suite. Inspired directly from the upstream Libtool patches that fix
|
|
the issue (but we need something working before the next Libtool
|
|
release).
|
|
|
|
|
|
1.4
|
|
---
|
|
|
|
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
|
|
-----
|
|
|
|
- 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.
|
|
- Fix some VT issues with MPI_BOTTOM/MPI_IN_PLACE.
|
|
- 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
|
|
-----
|
|
|
|
- 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
|
|
support for Debian's builtroot system). Thanks to Manuel Prinz and
|
|
the rest of the Debian crew for helping identify and fix this issue.
|
|
- Various minor fixes for the I/O forwarding subsystem.
|
|
- Big endian iWARP fixes in the Open Fabrics RDMA CM support.
|
|
- Update support for various OpenFabrics devices in the openib BTL's
|
|
.ini file.
|
|
- Fixed undefined symbol issue with Open MPI's parallel debugger
|
|
message queue support so it can be compiled by Sun Studio compilers.
|
|
- Update MPI_SUBVERSION to 1 in the Fortran bindings.
|
|
- Fix MPI_GRAPH_CREATE Fortran 90 binding.
|
|
- Fix MPI_GROUP_COMPARE behavior with regards to MPI_IDENT. Thanks to
|
|
Geoffrey Irving for identifying the problem and supplying the fix.
|
|
- Silence gcc 4.1 compiler warnings about type punning. Thanks to
|
|
Number Cruncher for the fix.
|
|
- Added more Valgrind and other memory-cleanup fixes. Thanks to
|
|
various Open MPI users for help with these issues.
|
|
- Miscellaneous VampirTrace fixes.
|
|
- More fixes for openib credits in heavy-congestion scenarios.
|
|
- Slightly decrease the latency in the openib BTL in some conditions
|
|
(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
|
|
-----
|
|
|
|
- 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.
|
|
- Allow empty shell designations from getpwuid(). Thanks to Sergey
|
|
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
|
|
-----
|
|
|
|
- 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 Dalcin 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.
|
|
- Improvements to the MPI C++ integer constants:
|
|
- 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
|
|
---
|
|
|
|
- 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.
|
|
|
|
|
|
1.2.9 (unreleased)
|
|

1.2.8
|
|
-----
|
|
|
|
- Tweaked one memory barrier in the openib component to be more conservative.

|
|
- Adjust SLURM support to first look for $SLURM_JOB_CPUS_PER_NODE instead of
|
|
the deprecated $SLURM_TASKS_PER_NODE environment variable. This change
|
|
may be *required* when using SLURM v1.2 and above. See ticket #1536.

-----
|
|
|
|
- Fix a regression in comm_spawn functionality that inadvertently
|
|
caused the mapping of child processes to always start at the same
|
|
place. Thanks to Prakash Velayutham for helping discover the
|
|
problem.
|
|
- Fix segfault when a user's home directory is unavailable on a remote

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
|

|
|
(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.
|
|
|
|
|
|

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.

|
|
MPI::Win::Get_attr.
|
|
- Fix math error on Intel OS X platforms that would greatly increase
|
|
shared memory latency.

- Fix several MPI_*ERRHANDLER* functions and MPI_GROUP_TRANSLATE_RANKS
|
|
with respect to what arguments they allowed and the behavior that
|
|
they effected. Thanks to Lisandro Dalcin for reporting the
|
|
problems.
|

|
mpirun to crash without doing anything).
|
|
- Fix for initialization hangs on 64 bit Mac OS X PowerPC systems.
|
|

|
|
- If using the Intel 9.0 v20051201 compiler on an IA64 platform, the

|
|
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
|
|
---
|
|
|
|
- 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.
|
|
|
|
|
|

|
|
functions (MPI_TESTSOME, MPI_TESTANY, MPI_TESTALL, MPI_WAITSOME,
|
|
MPI_WAITANY, MPI_WAITALL).

|
|
Solaris. Thanks to Pierre Valiron for reporting the issue.
|
|
- 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).
|
|

|
|
- Fix warnings about setting read-only MCA parameters on bproc systems.
|
|
- 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.
|
|
- Fixed umask issues in the session directory. Thanks to Glenn Morris
|
|
for reporting this to us.

|
|
rsh startup. Thanks to Glen Morris for finding these typos.
|
|
- Fixed missing constants in MPI C++ bindings.
|
|
- Fixed some errors caused by threading issues.
|
|
- Fixed openib BTL flow control logic to not overrun the number of
|
|
send wqes available.
|
|
- Update to match newest OpenIB user-level library API. Thanks to
|
|
Roland Dreier for submitting this patch.

|
|
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.
|
|
- Enable printing of stack traces in MPI processes upon SIGBUS,
|
|
SIGSEGV, and SIGFPE if the platform supports it.

|
|
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
