The next (and hopefully last) release candidate for the 4.1.5 release is posted at https://www.open-mpi.org/software/ompi/v4.1/.
Significant changes since the 2nd release candidate (we skipped the 3rd release candidate for logistical reasons) are: * Fixed a crash in the rdma osc component * Fixed a compilation issue in the OFI MTL when Open MPI is compiled with CUDA support * Updated PMIx to v3.2.4 (which includes a number of bug fixes not called out here) * UCC and UCX bug fixes. We would welcome any testing and feedback; barring any negative feedback we intend to ship 4.1.5 late next week. Thanks, Brian & Jeff
