- 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.
- Upgrade the embedded OpenPMIx to v3.2.1.
- Take more steps towards creating fully Reproducible builds (see
https://reproducible-builds.org/).
- 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.
- OFI MTL: Various bug fixes.
- Fixed issue where MPI_TYPE_CREATE_RESIZED would create a datatype
with unexpected extent on oddly-aligned datatypes.
- collectives: Add ADAPT adaptive collectives component. The
component is off by default and can be enabled by specifying --mca
coll_adapt_priority 100. We intend to turn on ADAPT by default in
Open MPI 5.0.
- collectives: Adjust default tuning thresholds for many collective
algorithms
- runtime: fix situation where rank-by argument does not work
