Change default openmpi to openmpi4
- openmpi4 is now the default openmpi for releases > 15.3
- 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

- 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.

* collectives: Add HAN and ADAPT adaptive collectives components.
Both components are off by default and can be enabled by specifying
"mpirun --mca coll_adapt_priority 100 --mca coll_han_priority 100 ...".
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
thanks to Mark Dixon for identifying MPI I/O issues and providing
access to Lustre systems for testing.
* Minor MPI one-sided RDMA performance improvements.
* Fix hcoll MPI_SCATTERV with MPI_IN_PLACE.
* Add AVX support for MPI collectives.

* runtime: Remove --enable-install-libpmix option, which has not
worked since it was added
* UCX: Allow UCX 1.8 to be used with the btl uct
* UCX: Replace usage of the deprecated NB API of UCX with NBX
* OMPIO: Add support for the IME file system
* OFI/libfabric: Added support for multiple NICs
