Summary: An implementation of MPI/SHMEM (Version 4)

OpenMPI is an implementation of the Message Passing Interface, a
standardized API typically used for parallel and/or distributed
computing. OpenMPI is the merged result of four prior implementations
where the team found for them to excel in one or more areas,
such as latency or throughput.

OpenMPI also includes an implementation of the OpenSHMEM parallel
programming API, which is a Partitioned Global Address Space (PGAS)
abstraction layer providing inter-process communication using
one-sided communication techniques.

This package provides general tools (mpirun, mpiexec, etc.) and the
Module Component Architecture (MCA) base and plugins necessary for
running Open MPI/OpenSHMEM version 4 jobs.

    - Fix a number of datatype issues, including an issue with
      improper handling of partial datatypes that could lead to
      an unexpected application failure.
    - Change UCX PML to not warn about MPI_Request leaks during
      MPI_FINALIZE by default.  The old behavior can be restored with
      the mca_pml_ucx_request_leak_check MCA parameter.
    - Reverted temporary solution that worked around launch issues in
      SLURM v20.11.{0,1,2}. SchedMD encourages users to avoid these

    - Updated PMIx to v3.2.2.
    - Disabled gcc built-in atomics by default on aarch64 platforms.
    - Disabled UCX PML when UCX v1.8.0 is detected. UCX version 1.8.0 has a bug that
      may cause data corruption when its TCP transport is used in conjunction with
      the shared memory transport. UCX versions prior to v1.8.0 are not affected by
      this issue. Thanks to @ksiazekm for reporting the issue.
    - Fixed detection of available UCX transports/devices to better inform PML
    - Fixed SLURM support to mark ORTE daemons as non-MPI tasks.
    - Improved AVX detection to more accurately detect supported
      platforms.  Also improved the generated AVX code, and switched to
      using word-based MCA params for the op/avx component (vs. numeric
      big flags).
    - Improved OFI compatibility support and fixed memory leaks in error
      handling paths.
    - Improved HAN collectives with support for Barrier and Scatter. Thanks
      to @EmmanuelBRELLE for these changes and the relevant bug fixes.
    - Fixed MPI debugger support (i.e., the MPIR_Breakpoint() symbol).
      Thanks to @louisespellacy-arm for reporting the issue.
    - Fixed ORTE bug that prevented debuggers from reading MPIR_Proctable.
    - Removed PML uniformity check from the UCX PML to address performance
    - Fixed MPI_Init_thread(3) statement about C++ binding and update
      references about MPI_THREAD_MULTIPLE.  Thanks to Andreas Lösel for
      bringing the outdated docs to our attention.
    - Added fence_nb to Flux PMIx support to address segmentation faults.
    - Ensured progress of AIO requests in the POSIX FBTL component to
      prevent exceeding maximum number of pending requests on MacOS.
    - Used OPAL's mutli-thread support in the orted to leverage atomic
      operations for object refcounting.
    - Fixed segv when launching with static TCP ports.
    - Fixed --debug-daemons mpirun CLI option.
    - Fixed bug where mpirun did not honor --host in a managed job
    - Made a managed allocation filter a hostfile/hostlist.
    - Fixed bug to marked a generalized request as pending once initiated.
    - Fixed external PMIx v4.x check.
    - Fixed OSHMEM build with `--enable-mem-debug`.
    - Fixed a performance regression observed with older versions of GCC when
      __ATOMIC_SEQ_CST is used. Thanks to @BiplabRaut for reporting the issue.
    - Fixed buffer allocation bug in the binomial tree scatter algorithm when
      non-contiguous datatypes are used. Thanks to @sadcat11 for reporting the issue.
    - Fixed bugs related to the accumulate and atomics functionality in the
      osc/rdma component.
    - Fixed race condition in MPI group operations observed with
      MPI_THREAD_MULTIPLE threading level.
    - Fixed a deadlock in the TCP BTL's connection matching logic.
    - Fixed pml/ob1 compilation error when CUDA support is enabled.
    - Fixed a build issue with Lustre caused by unnecessary header includes.
    - Fixed a build issue with IMB LSF workload manager.
    - Fixed linker error with UCX SPML.

      We intend to enable both by default in Open MPI 5.0.
    * OMPIO is now the default for MPI-IO on all filesystems, including
      Lustre (prior to this, ROMIO was the default for Lustre).  Many
