The Open MPI Team is pleased to release version 1.0.2 of Open MPI. This
is primarily a bug-fix release. Version 1.0.2 can be downloaded from
the main Open MPI web site or any of its mirrors (mirrors will be
updating shortly).
Here are a list of changes in v1.0.2 as compared to v1.0.1:
- Fixed assembly race condition on AMD64 platforms.
- Fixed residual .TRUE. issue with copying MPI attributes set from
Fortran.
- Remove unnecessary logic from Solaris pty I/O forwarding. Thanks to
Francoise Roch for bringing this to our attention.
- Fixed error when count = 0 was given for multiple completion MPI
functions (MPI_TESTSOME, MPI_TESTANY, MPI_TESTALL, MPI_WAITSOME,
MPI_WAITANY, MPI_WAITALL).
- Better handling in MPI_ABORT for when peer processes have already
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).
