===========================================================================
|
||
|
||
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.
|
||
|
||
Trunk (not on release branches yet)
|
||
-----------------------------------
|
||
|
||
- Revamped autogen / build system.
|
||
- ErrMgr framework redesigned to better support fault tolerance development
|
||
activities. See the following RFC for details:
|
||
http://www.open-mpi.org/community/lists/devel/2010/03/7589.php
|
||
- Add new sensor framework to ORTE that includes modules for detecting
|
||
stalled applications and processes that consume too much memory.
|
||
- Add new state framework to ORTE for saving and retrieving state
|
||
information (both application and system) to/from a database.
|
||
- Add new "orte-info" tool that provides MCA params for only ORTE and
|
||
OPAL levels - intended for use when configuring without MPI support
|
||
- Modified paffinity system to provide warning when bindings result in
|
||
being "bound to all", which is equivalent to "not bound"
|
||
- Added MPI-3 function: MPI_GET_LIBRARY_VERSION
|
||
- Added MPI-3 matched probe interface.
|
||
- Revamped Fortran MPI bindings:
|
||
- mpifort wrapper compiler
|
||
- "use mpi_f08" bindings (for compilers that support it)
|
||
- better "use mpi" support (for compilers that support it)
|
||
- Enabled compile-time warning of deprecated MPI functions by default
|
||
(in supported compilers).
|
||
- Added a new MCA parameter (ess_base_stream_buffering) that allows the user
|
||
to override the system default for buffering of stdout/stderr streams
|
||
(via setvbuf).
|
||
- Added support for the DMTCP checkpoint/restart system.
|
||
- Removed maffinity, paffinity, and carto frameworks (and associated MCA params).
|
||
|
||
|
||
1.6
|
||
---
|
||
|
||
- 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).
|

|
||
return immediately with MPI_SUCCESS. Thanks to Jeremiah Willcock
|
||

- 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.
|
||

|
||
callback functions.
|
||
- Fix a bunch of minor C++ API issues; thanks to Fujitsu for the patch.

||
|
||
|
||

||
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:

|
||
interface for each MPI process on a node. This parameter is only
|
||
useful when used with virtual ethernet interfaces on a single
|
||
network card (e.g., when using virtual interfaces give dedicated
|
||
hardware resources on the NIC to each process).
|

|
||
and the README file for more details.
|
||
- Updated shared library versioning scheme and linking style of MPI
|
||
applications. The MPI application ABI has been broken from the
|
||
v1.3/v1.4 series. MPI applications compiled against any prior
|
||
version of Open MPI will need to, at a minimum, re-link. See the
|
||
README file for more details.
|
||
- Added "fca" collective component, enabling MPI collective offload
|
||
support for Voltaire switches.
|
||
- Fixed MPI one-sided operations with large target displacements.

|
||
bindings. Thanks to Paul Kapinos for pointing out the issue
|
||
(** also to appear: 1.4.3).
|
||
- Fixed extra_state parameter types in F90 prototypes for
|
||
MPI_COMM_CREATE_KEYVAL, MPI_GREQUEST_START, MPI_REGISTER_DATAREP,
|
||
MPI_TYPE_CREATE_KEYVAL, and MPI_WIN_CREATE_KEYVAL.
|
||
- Fixes for Solaris oversubscription detection.
|
||
- If the PML determines it can't reach a peer process, print a
|
||
slightly more helpful message. Thanks to Nick Edmonds for the
|
||
suggestion.
|
||
- Make btl_openib_if_include/exclude function the same way
|
||
btl_tcp_if_include/exclude works (i.e., supplying an _include list
|
||
overrides supplying an _exclude list).
|
||
- Apply more scalable reachability algorithm on platforms with more
|
||
than 8 TCP interfaces.
|
||
- Various assembly code updates for more modern platforms / compilers.
|
||

one-sided operations. Users beware; not all MPI datatypes are valid
|
||
for use with one-sided operations!
|
||
- Improve behavior of MPI_COMM_SPAWN with regards to --bynode.
|
||
- Various threading fixes in the openib BTL and other core pieces of
|
||
Open MPI.

|
||
process failures.
|
||
- Print warnings if shared memory state files are opened on what look
|
||
like networked filesystems.
|
||
- Update libevent to v1.4.13.
|
||
- Allow propagating signals to processes that call fork().
|
||
- Fix bug where MPI_GATHER was sometimes incorrectly examining the
|
||
datatype on non-root processes. Thanks to Michael Hofmann for
|
||
investigating the issue.
|
||
- Various Microsoft Windows fixes.
|
||
- Various Catamount fixes.
|
||
- Various checkpoint / restart fixes.
|
||
- Xgrid support has been removed until it can be fixed (patches
|
||
would be welcome).
|
||
- Added simplistic "libompitrace" contrib package. Using the MPI
|
||
profiling interface, it essentially prints out to stderr when select
|
||
MPI functions are invoked.
|
||
- Update bundled VampirTrace to v5.8.2.
|
||
- Add pkg-config(1) configuration files for ompi, ompi-c, ompi-cxx,
|
||
ompi-f77, ompi-f90. See the README for more details.
|
||
- Removed the libopenmpi_malloc library (added in the v1.3 series)
|
||
since it is no longer necessary
|
||
- Add several notifier plugins (generally used when Open MPI detects

||
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.
|
||
|
||
|
||

|
||
- Fix some internal copying functions in Open MPI's use of PLPA.
|
||

||
change the environment variable that we use for obtaining the job's
|
||
allocation.
|
||
- Revert to an older, safer (but slower) communicator ID allocation
|
||
algorithm.

- 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.

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.
|
||

|
||
- 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
|
||

|
||
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)
|
||
------------------

|
||
See ticket #1580.
|
||
|
||

-----
|
||
|
||
- Tweaked one memory barrier in the openib component to be more conservative.
|
||
May fix a problem observed on PPC machines. See ticket #1532.
|
||
- Fix OpenFabrics IB partition support. See ticket #1557.
|
||

|
||
shell will not do so (e.g. /bin/sh and /bin/ksh). See ticket #1560.
|
||
- Fix segfault in MPI_Init_thread() if ompi_mpi_init() fails. See ticket #1562.
|
||
- Adjust SLURM support to first look for $SLURM_JOB_CPUS_PER_NODE instead of

|
||
problems seen on InfiniBand in some cases. See ticket #1224.
|
||
- Sanitized some #define macros used in mpi.h to avoid compiler warnings
|
||
caused by MPI programs built with different autoconf versions.
|
||
Thanks to Ben Allan for reporting the problem, and thanks to
|
||
Brian Barrett for the fix. See ticket #1220.
|
||
- Some man page fixes from the Debian maintainers. See ticket #1219.

libibverbs >=v1.1 (i.e., OFED 1.2 and beyond).
|
||
|
||
|
||
1.2.3
|
||
-----
|
||
|
||
- 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

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.
|

died, especially under some resource managers.
|
||
- Random updates to README file, to include notes about the Portland
|
||
compilers.
|
||
- Random, small threading fixes to prevent deadlock.
|
||
- Fixed a problem with handling long mpirun app files. Thanks to Ravi
|
||
Manumachu for identifying the problem.
|
||
- Fix handling of strings in several of the Fortran 77 bindings.
|
||
- Fix LinuxPPC assembly issues. Thanks to Julian Seward for reporting
|
||
the problem.
|
||
- Enable pty support for standard I/O forwarding on platforms that
|
||
have ptys but do not have openpty(). Thanks to Pierre Valiron for
|
||
bringing this to our attention.
|
||
- Disable inline assembly for PGI compilers to avoid compiler errors.
|
||
Thanks to Troy Telford for bringing this to our attention.
|
||
- Added MPI_UNSIGNED_CHAR and MPI_SIGNED_CHAR to the allowed reduction
|
||
types.
|
||
- Fix a segv in variable-length message displays on Opterons running
|
||
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 race condition in shared memory transport that could cause
|
||
crashes on machines with weak memory consistency models (including
|
||
POWER/PowerPC machines).
|
||
- 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.
|
||
- Fixed tcsh-based LD_LIBRARY_PATH issues with --prefix. Thanks to
|
||
Glen Morris for identifying the problem and suggesting the fix.
|
||
- Removed extraneous \n's when setting PATH and LD_LIBRARY_PATH in the
|
||
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.
|
||
- Report errors properly when failing to register memory in the openib
|
||
BTL.
|
||
- Reduce memory footprint of openib BTL.
|
||
- Fix parsing problem with mpirun's "-tv" switch. Thanks to Chris
|
||
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.
|
||
- Fixed F90 compilation support for the Lahey compiler.
|
||
- Fixed issues with ROMIO shared library support.
|
||
- Fixed internal accounting problems with rsh support.
|
||
- Update to GNU Libtool 1.5.22.
|
||
- Fix error in configure script when setting CCAS to ias (the Intel
|
||
assembler).
|
||
- Added missing MPI::Intercomm collectives.
|
||
- Fixed MPI_IN_PLACE handling for Fortran collectives.
|
||
- Fixed some more C++ const_cast<> issues. Thanks for Martin Audet
|
||
(again) for bringing this to our attention.
|
||
- Updated ROMIO with the version from MPICH 1.2.7p1, marked as version
|
||
2005-06-09.
|
||
- Fixes for some cases where the use of MPI_BOTTOM could cause
|
||
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).
|
||
|
||
|
||
1.0.1
|
||
-----
|
||
|
||
- Fixed assembly on Solaris AMD platforms. Thanks to Pierre Valiron
|
||
for bringing this to our attention.
|
||
- Fixed long messages in the send-to-self case.
|
||
- Ensure that when the "leave_pinned" option is used, the memory hooks
|
||
are also enabled. Thanks to Gleb Natapov for pointing this out.
|
||
- Fixed compile errors for IRIX.
|
||
- Allow hostfiles to have integer host names (for BProc clusters).
|
||
- Fixed a problem with message matching of out-of-order fragments in
|
||
multiple network device scenarios.
|
||
- Converted all the C++ MPI bindings to use proper const_cast<>'s
|
||
instead of old C-style casts to get rid of const-ness. Thanks to
|
||
Martin Audet for raising the issue with us.
|
||
- Converted MPI_Offset to be a typedef instead of a #define because it
|
||
causes problems for some C++ parsers. Thanks to Martin Audet for
|
||
bringing this to our attention.
|
||
- Improved latency of TCP BTL.
|
||
- Fixed index value in MPI_TESTANY to be MPI_UNDEFINED if some
|
||
requests were not MPI_REQUEST_NULL, but no requests finished.
|
||
- Fixed several Fortran MPI API implementations that incorrectly used
|
||
integers instead of logicals or address-sized integers.
|
||
- Fix so that Open MPI correctly handles the Fortran value for .TRUE.,
|
||
regardless of what the Fortran compiler's value for .TRUE. is.
|
||
- Improved scalability of MX startup.
|
||
- Fix datatype offset handling in the coll basic component's
|
||
MPI_SCATTERV implementation.
|
||
- Fix EOF handling on stdin.
|
||
- Fix missing MPI_F_STATUS_IGNORE and MPI_F_STATUSES_IGNORE
|
||
instanatiations. Thanks to Anthony Chan for pointing this out.
|
||
- Add a missing value for MPI_WIN_NULL in mpif.h.
|
||
- Bring over some fixes for the sm btl that somehow didn't make it
|
||
over from the trunk before v1.0. Thanks to Beth Tibbitts and Bill
|
||
Chung for helping identify this issue.
|
||
- Bring over some fixes for the iof that somehow didn't make it over
|
||
from the trunk before v1.0.
|
||

|
||
pointing this out to us.
