|
|
|
|
|
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
|
|
node. Thanks to Guillaume Thomas-Collignon for bringing the issue
|
|
to our attention.
|
|
- Fix MPI_IPROBE to properly handle MPI_STATUS_IGNORE on mx and psm
|
|
MTLs. Thanks to Sophia Corwell for finding this and supplying a
|
|
reproducer.
|
|
- Fix some error messages in the tcp BTL.
|
|
- Use _NSGetEnviron instead of environ on Mac OS X so that there
|
|
are no undefined symbols in the shared libraries.
|
|
- On OS X, when MACOSX_DEPLOYMENT_TARGET is 10.3 or higher, support
|
|
building the Fortran 90 bindings as a shared library. Thanks to
|
|
Jack Howarth for his advice on making this work.
|
|
- No longer require extra include flag for the C++ bindings.
|
|
- Fix detection of weak symbols support with Intel compilers.
|

|
|
MCA parameters set in the environment properly.
|
|
- Rename the oob_tcp_include/exclude MCA params to oob_tcp_if_include/exclude
|
|
so that they match the naming convention of the btl_tcp_if_include/exclude
|
|
params. The old names are depreciated, but will still work.
|
|
- Add -wd as a synonym for the -wdir orterun/mpirun option.
|
|
- Fix the mvapi BTL to compile properly with compilers that do not support
|
|
anonymous unions. Thanks to Luis Kornblueh for reporting the bug.
|
|
|
|
|
|

1.2
|
|
---
|
|
|
|

|
|
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

|
|
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.
|
|
- Fixes for MPI_STATUS_SET_ELEMENTS.
|
|
- Print better error messages when mpirun's "-nolocal" is used when
|
|
there is only one node available.
|
|
- Added man pages for several Open MPI executables and the MPI API
|
|
functions.
|
|

|
|
- Build the Fortran MPI API as a separate library to allow these
|
|
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.
|
|

|
- Addition of "cm" PML to better support library-level matching
|
|
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
|
|
-----
|
|
|
|
- Implement MPI_TYPE_CREATE_DARRAY function.
|
|
- Fix race condition in shared memory BTL startup that could cause MPI
|
|
applications to hang in MPI_INIT.

|
|
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.
|

|
|
- 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
|
|
the problem.
|
|
- Include both pre- and post-MPI-2 errata bindings for
|
|
MPI::Win::Get_attr.
|
|
- Fix math error on Intel OS X platforms that would greatly increase
|
|
shared memory latency.
|
|

in the MPI F77 bindings functions. Thanks to Pierre-Matthieu
|
|
Anglade for bringing this problem to our attention.
|
|
- Fix for a memory leak in the derived datatype function
|
|
ompi_ddt_duplicate(). Thanks to Andreas Schafer for reporting,
|
|
diagnosing, and patching the leak.
|
|
- Used better performing basic algorithm for MPI_ALLGATHERV.
|
|
- Added a workaround for a bug in the Intel 9.1 C++ compiler (all
|
|
versions up to and including 20060925) in the MPI C++ bindings that

caused run-time failures. Thanks to Scott Weitzenkamp for reporting
|
|
this problem.
|
|

|
|
missing MPI::Grequest functionality to the C++ bindings.
|
|
- Add "mpi_preconnect_all" MCA parameter to force wireup of all MPI
|
|
connections during MPI_INIT (vs. making connections lazily whenever
|
|
the first MPI communication occurs between a pair of peers).
|

|
|
tokens. Thanks to Orion Poplawski for identifying the problem and
|
|
to Ralf Wildenhues for suggesting the fix.
|
|
- 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.

|
|
1.1
|
|
---
|
|
|
|
- Various MPI datatype fixes, optimizations.
|
|
- Fixed various problems on the SPARC architecture (e.g., not

|
between different F90 compilers.
|
|
- Addition of "trivial", "small" (the default), and "medium"
|
|

|
|
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.
|

- 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.
|
|
|
|
|
|

|
|
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.
|
|

|
- 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.

|
|
Glen Morris for identifying the problem and suggesting the fix.

|
|
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 issues with ROMIO shared library support.
|
|
- Fixed internal accounting problems with rsh support.
|
|
- Update to GNU Libtool 1.5.22.
|

|
|
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).
|
|
|
|
|
|

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

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
