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
