- Update to 4.3.0
- Support MPI memory allocation kinds side document.
- Support MPI ABI Proposal. Configure with --enable-mpi-abi and build with
mpicc_abi. By default, mpicc still builds and links with MPICH ABI.
- Added benchmark tests test/mpi/bench/p2p_{latency,bw}.
- Added CMA support in CH4 IPC.
- Added IPC read algorithm for intranode Allgather and Allgatherv.
- Added CVAR MPIR_CVAR_CH4_SHM_POSIX_TOPO_ENABLE to enable non-temporal memcpy
for inter-numa shm communication.
- Added CVAR MPIR_CVAR_DEBUG_PROGRESS_TIMEOUT for debugging MPI deadlock issues.
- ch4:ucx now supports dynamic processes. MPI_Comm_spawn{_multiple} will work.
MPI_Open_port will fail due to ucx port name exceeds current MPI_MAX_PORT_NAME
of 256. One can work around by use an info hint "port_name_size" and use a
larger port name buffer.
- PMI-1 defines PMI_MAX_PORT_NAME, which may be different from MPI_MAX_PORT_NAME.
This is used by "PMI_Lookup_name". Consequently, MPI_Lookup_name accepts info
hint "port_name_size" that may be larger than MPI_MAX_PORT_NAME. If the port
name does not fit in "port_name_size", it will return a truncation error.
- Autogen default to use -yaksa-depth=2.
- Default MPIR_CVAR_CH4_ROOTS_ONLY_PMI to on.
- Added ch4 netmod API am_tag_send and am_tag_recv.
- Added MPIR_CVAR_CH4_OFI_EAGER_THRESHOLD to force RNDV send mode.
- Make check target will run ROMIO tests.
- Add back handle conversion macros (f2c/c2f) to preserve ABI
compatibility with older MPICH libraries
- Fix compilation issue with g++ in -std=gnu++20 mode
- Fix bug in MPI_ANY_SOURCE handling observed using the libfabric CXI
provider
- Add NIC information to error messages in ch4:ofi netmod
- Add romio-disable-tests.patch to disable romio tests
