===========================================================================
|
||
|
||
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
|
||

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"
|
||

|
||
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.

|
||
support for Voltaire switches.
|

|
||
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.
|
||
- Relax restrictions on using certain kinds of MPI datatypes with
|
||
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.

|
||
- Various FreeBSD and NetBSD updates and fixes. Thanks to Kevin
|
||
Buckley and Aleksej Saushev for their work.
|
||
- Fix case where freeing communicators in MPI_FINALIZE could cause
|
||
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 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
|
||
system/network administrator-worthy problems); each have their own
|
||
MCA parameters to govern their usage. See "ompi_info --param
|
||
notifier <name>" for more details.
|
||
- command to execute arbitrary commands (e.g., run a script).
|
||
- file to send output to a file.
|
||
- ftb to send output to the Fault Tolerant Backplane (see
|
||
http://wiki.mcs.anl.gov/cifts/index.php/CIFTS)

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

- 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.
|

|
||
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.

|
||
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
|

|
||
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
|

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
|
||

||
- 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.
|
||
|
||
|

has gaps in the beginning.
|
||
- Fix an error that limited the number of comm_spawns that could
|
||
simultaneously be running in some environments
|

|
||
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
|

|
||
features.
|
||
- Fix SLURM race condition.
|
||

|
||
- Various fixes for size disparity between C int's and Fortran
|
||
INTEGER's. Thanks to Christoph van Wullen for the bug report.
|
||

|
||
processes abort or fail to launch.
|
||

|
||
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.
|

||
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)
|
||

|
||
- Sanitized some #define macros used in mpi.h to avoid compiler warnings
|
||
caused by MPI programs built with different autoconf versions.

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
|

|
||
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.
|
||

- 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.
|
||

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.

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.
|

||
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)

equivalent to "medium"). See the README file for more
|
||
explanation.
|

- 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

|
||
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.

- 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

|
||
- 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

|
||
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.

- 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.
|
||
- Fix for --with-wrapper-ldflags handling. Thanks to Dries Kimpe for
|
||
pointing this out to us.
