The third (and possibly final) release candidate for the Open MPI v4.0.2 release is posted at https://www.open-mpi.org/software/ompi/v4.0/
Fixes since 4.0.2rc2 include:
- Silent failure of OMPI over OFI with large messages sizes. - Conform MPIR_Breakpoint to MPIR standard. - btl/vader: when using single-copy emulation, fragment large rdma. - restore compilation of smpl/ikrit. Our goal is to release 4.0.2 in the next week. All testing and feedback is appreciated. Thanks, your Open MPI release team
