Package: openmpi-bin Version: 3.1.3-11 Severity: serious Hi,
This is tracked upstream as https://github.com/open-mpi/ompi/issues/7035 . mpirun segfaults during MTL OFI provider section when run on a machine with an InfiniBand network. This happens for the following reason: Until version 3.1.2, OFI used an opt-in mechanism to include providers. 'verbs' wasn't included by default. This was changed by https://github.com/open-mpi/ompi/commit/d00c387284b6197946452a0938e76615a17fa689 The discussion is still ongoing upstream, but it looks like this might be related to the libfabric version in Debian. The chosen solution upstream might be to disable the 'verbs' provider. Also, v4.x is not affected. I believe this should be fixed in stable. Infiniband is common in HPC clusters, so a broken OpenMPI is of limited use without its support.
