3.0.0 -- July, 2017
|
||||||
|
-------------------
|
||||||
|
|
||||||
|
Major new features:
|
||||||
|
|
||||||
|
- Use UCX allocator for OSHMEM symmetric heap allocations to optimize intra-node
|
||||||
|
data transfers. UCX SPML only.
|
||||||
|
- Use UCX multi-threaded API in the UCX PML. Requires UCX 1.0 or later.
|
||||||
|
|
||||||
|
Changes in behavior compared to prior versions:
|
||||||
|
|
||||||
|
Removed legacy support:
|
||||||
|
- "yoda" SPML component is removed from the Open SHMEM codebase. It was utilizing
|
||||||
|
Open MPI BTL components for supported networks.
|
||||||
|
Currently avalable SPML components are:
|
||||||
|
- "ikrit" based on Mellanox Messaging Accelerator (MXM) communication library;
|
||||||
|
- "ucx" based on the open-source Unified Communication X (UCX) communication
|
||||||
|
library (http://www.openucx.org/).

2.1.0 -- March, 2017
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
Major new features:
|
||||||
|
|
||||||
|
- The main focus of the Open MPI v2.1.0 release was to update to PMIx
|
||||||
|
v1.2.1. When using PMIx (e.g., via mpirun-based launches, or via
|
||||||
|
direct launches with recent versions of popular resource managers),
|
||||||
|
launch time scalability is improved, and the run time memory
|
||||||
|
footprint is greatly decreased when launching large numbers of MPI /
|
||||||
|
OpenSHMEM processes.
|
||||||
|
- Update OpenSHMEM API conformance to v1.3.
|
||||||
|
- The usnic BTL now supports MPI_THREAD_MULTIPLE.
|
||||||
|
- General/overall performance improvements to MPI_THREAD_MULTIPLE.
|
||||||
|
- Add a summary message at the bottom of configure that tells you many
|
||||||
|
of the configuration options specified and/or discovered by Open
|
||||||
|
MPI.
|
||||||
|
|
||||||
|
Changes in behavior compared to prior versions:
|
||||||
|
|
||||||
|
- None.
|
||||||
|
|
||||||
|
Removed legacy support:
|
||||||
|
|
||||||
|
- The ptmalloc2 hooks have been removed from the Open MPI code base.
|
||||||
|
This is not really a user-noticable change; it is only mentioned
|
||||||
|
here because there was much rejoycing in the Open MPI developer
|
||||||
|
community.
|
||||||
|
|
||||||
|
Bug fixes/minor improvements:
|
||||||
|
|
||||||
|
- New MCA parameters:
|
||||||
|
- iof_base_redirect_app_stderr_to_stdout: as its name implies, it
|
||||||
|
combines MPI / OpenSHMEM applications' stderr into its stdout
|
||||||
|
stream.
|
||||||
|
- opal_event_include: allow the user to specify which FD selection
|
||||||
|
mechanism is used by the underlying event engine.
|
||||||
|
- opal_stacktrace_output: indicate where stacktraces should be sent
|
||||||
|
upon MPI / OpenSHMEM process crashes ("none", "stdout", "stderr",
|
||||||
|
"file:filename").
|
||||||
|
- orte_timeout_for_stack_trace: number of seconds to wait for stack
|
||||||
|
traces to be reported (or <=0 to wait forever).
|
||||||
|
- mtl_ofi_control_prog_type/mtl_ofi_data_prog_type: specify libfabric
|
||||||
|
progress model to be used for control and data.
|
||||||
|
- Fix MPI_WTICK regression where the time reported may be inaccurate
|
||||||
|
on systems with processor frequency scalaing enabled.
|
||||||
|
- Fix regression that lowered the memory maximum message bandwidth for
|
||||||
|
large messages on some BTL network transports, such as openib, sm,
|
||||||
|
and vader.
|
||||||
|
- Fix a name collision in the shared file pointer MPI IO file locking
|
||||||
|
scheme. Thanks to Nicolas Joly for reporting the issue.
|
||||||
|
- Fix datatype extent/offset errors in MPI_PUT and MPI_RACCUMULATE
|
||||||
|
when using the Portals 4 one-sided component.
|
||||||
|
- Add support for non-contiguous datatypes to the Portals 4 one-sided
|
||||||
|
component.
|
||||||
|
- Various updates for the UCX PML.
|
||||||
|
- Updates to the following man pages:
|
||||||
|
- mpirun(1)
|
||||||
|
- MPI_COMM_CONNECT(3)
|
||||||
|
- MPI_WIN_GET_NAME(3). Thanks to Nicolas Joly for reporting the
|
||||||
|
typo.
|
||||||
|
- MPI_INFO_GET_[NKEYS|NTHKEY](3). Thanks to Nicolas Joly for
|
||||||
|
reporting the typo.
|
||||||
|
- Fixed a problem in the TCP BTL when using MPI_THREAD_MULTIPLE.
|
||||||
|
Thanks to Evgueni Petrov for reporting.
|
||||||
|
- Fixed external32 representation in the romio314 module. Note that
|
||||||
|
for now, external32 representation is not correctly supported by the
|
||||||
|
ompio module. Thanks to Thomas Gastine for bringing this to our
|
||||||
|
attention.
|
||||||
|
- Add note how to disable a warning message about when a high-speed
|
||||||
|
MPI transport is not found. Thanks to Susan Schwarz for reporting
|
||||||
|
the issue.
|
||||||
|
- Ensure that sending SIGINT when using the rsh/ssh launcher does not
|
||||||
|
orphan children nodes in the launch tree.
|
||||||
|
- Fix the help message when showing deprecated MCA param names to show
|
||||||
|
the correct (i.e., deprecated) name.
|
||||||
|
- Enable support for the openib BTL to use multiple different
|
||||||
|
InfiniBand subnets.
|
||||||
|
- Fix a minor error in MPI_AINT_DIFF.
|
||||||
|
- Fix bugs with MPI_IN_PLACE handling in:
|
||||||
|
- MPI_ALLGATHER[V]
|
||||||
|
- MPI_[I][GATHER|SCATTER][V]
|
||||||
|
- MPI_IREDUCE[_SCATTER]
|
||||||
|
- Thanks to all the users who helped diagnose these issues.
|
||||||
|
- Allow qrsh to tree spawn (if the back-end system supports it).
|
||||||
|
- Fix MPI_T_PVAR_GET_INDEX to return the correct index.
|
||||||
|
- Correctly position the shared file pointer in append mode in the
|
||||||
|
OMPIO component.
|
||||||
|
- Add some deprecated names into shmem.h for backwards compatibility
|
||||||
|
with legacy codes.
|
||||||
|
- Fix MPI_MODE_NOCHECK support.
|
||||||
|
- Fix a regression in PowerPC atomics support. Thanks to Orion
|
||||||
|
Poplawski for reporting the issue.
|
||||||
|
- Fixes for assembly code with aggressively-optimized compilers on
|
||||||
|
x86_64/AMD64 platforms.
|
||||||
|
- Fix one more place where configure was mangling custom CFLAGS.
|
||||||
|
Thanks to Phil Tooley (@Telemin) for reporting the issue.
|
||||||
|
- Better handle builds with external installations of hwloc.
|
||||||
|
- Fixed a hang with MPI_PUT and MPI_WIN_LOCK_ALL.
|
||||||
|
- Fixed a bug when using MPI_GET on non-contiguous datatypes and
|
||||||
|
MPI_LOCK/MPI_UNLOCK.
|
||||||
|
- Fixed a bug when using POST/START/COMPLETE/WAIT after a fence.
|
||||||
|
- Fix configure portability by cleaning up a few uses of "==" with
|
||||||
|
"test". Thanks to Kevin Buckley for pointing out the issue.
|
||||||
|
- Fix bug when using darrays with lib and extent of darray datatypes.
|
||||||
|
- Updates to make Open MPI binary builds more bit-for-bit
|
||||||
|
reproducable. Thanks to Alastair McKinstry for the suggestion.
|
||||||
|
- Fix issues regarding persistent request handling.
|
||||||
|
- Ensure that shmemx.h is a standalone OpenSHMEM header file. Thanks
|
||||||
|
to Nick Park (@nspark) for the report.
|
||||||
|
- Ensure that we always send SIGTERM prior to SIGKILL. Thanks to Noel
|
||||||
|
Rycroft for the report.
|
||||||
|
- Added ConnectX-5 and Chelsio T6 device defaults for the openib BTL.
|
||||||
|
- OpenSHMEM no longer supports MXM less than v2.0.
|
||||||
|
- Plug a memory leak in ompi_osc_sm_free. Thanks to Joseph Schuchart
|
||||||
|
for the report.
|
||||||
|
- The "self" BTL now uses less memory.
|
||||||
|
- The vader BTL is now more efficient in terms of memory usage when
|
||||||
|
using XPMEM.
|
||||||
|
- Removed the --enable-openib-failover configure option. This is not
|
||||||
|
considered backwards-incompatible because this option was stale and
|
||||||
|
had long-since stopped working, anyway.
|
||||||
|
- Allow jobs launched under Cray aprun to use hyperthreads if
|
||||||
|
opal_hwloc_base_hwthreads_as_cpus MCA parameter is set.
|
||||||
|
- Add support for 32-bit and floating point Cray Aries atomic
|
||||||
|
operations.
|
||||||
|
- Add support for network AMOs for MPI_ACCUMULATE, MPI_FETCH_AND_OP,
|
||||||
|
and MPI_COMPARE_AND_SWAP if the "ompi_single_intrinsic" info key is
|
||||||
|
set on the window or the "acc_single_intrinsic" MCA param is set.
|
||||||
|
- Automatically disqualify RDMA CM support in the openib BTL if
|
||||||
|
MPI_THREAD_MULTIPLE is used.
|
||||||
|
- Make configure smarter/better about auto-detecting Linux CMA
|
||||||
|
support.
|
||||||
|
- Improve the scalability of MPI_COMM_SPLIT_TYPE.
|
||||||
|
- Fix the mixing of C99 and C++ header files with the MPI C++
|
||||||
|
bindings. Thanks to Alastair McKinstry for the bug report.
|
||||||
|
- Add support for ARM v8.
|
||||||
|
- Several MCA parameters now directly support MPI_T enumerator
|
||||||
|
semantics (i.e., they accept a limited set of values -- e.g., MCA
|
||||||
|
parameters that accept boolean values).
|
||||||
|
- Added --with-libmpi-name=STRING configure option for vendor releases
|
||||||
|
of Open MPI. See the README for more detail.
|
||||||
|
- Fix a problem with Open MPI's internal memory checker. Thanks to Yvan
|
||||||
|
Fournier for reporting.
|
||||||
|
- Fix a multi-threaded issue with MPI_WAIT. Thanks to Pascal Deveze for
