- Update to version 4.1.0
* 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.
* Updates to mpirun(1) about "slots" and PE=x values.
* Fix buffer allocation for large environment variables. Thanks to
@zrss for reporting the issue.
* Upgrade the embedded OpenPMIx to v3.2.2.
* Fix issue with extra-long values in MCA files. Thanks to GitHub
user @zrss for bringing the issue to our attention.
* UCX: Fix zero-sized datatype transfers.
* Fix --cpu-list for non-uniform modes.
* Fix issue in PMIx callback caused by missing memory barrier on Arm platforms.
* OFI MTL: Various bug fixes.
* Fixed issue where MPI_TYPE_CREATE_RESIZED would create a datatype
with unexpected extent on oddly-aligned datatypes.
* collectives: Adjust default tuning thresholds for many collective
algorithms
* runtime: fix situation where rank-by argument does not work
* Portals4: Clean up error handling corner cases
* 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
* OFI/libfabric: Added support for Scalable Endpoints
* OFI/libfabric: Added btl for one-sided support
* OFI/libfabric: Multiple small bugfixes
* libnbc: Adding numerous performance-improving algorithms
- Removed: reproducible.patch - replaced by spec file settings.
