A powerful implementaion of MPI2

Edit Package openmpi4

Open MPI is a project combining technologies and resources from several
other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in order to
build the best MPI library available.

This RPM contains all the tools necessary to compile, link, and run
Open MPI jobs.

Latest Revision
Gustavo Yokoyama Ribeiro's avatar Gustavo Yokoyama Ribeiro (gyribeiro) committed (revision 2)
- openmpi4 is now the default openmpi for releases > 15.3 (jsc#SLE-19268)
- Add orted-mpir-add-version-to-shared-library.patch to fix unversionned library
- Change RPM macros install path to %{_rpmmacrodir}

- Update to version 4.1.1
  - 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
    versions and to upgrade to v20.11.3 or newer.
  - 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
    prioritization.
  - 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
