osc/rdma: ensure bml add_procs has been called for all local procs#8452
Conversation
This fixes a bug when ob1 was not selected as the pml but osc/rdma may be selected for an MPI window. In some cases we may use btl/sm. If this is the case we need to ensure btl/sm knows about all the local procs (not just the ones in the communicator). This is required for btl/sm to correctly function at this time. In the future btl/sm should be made more resilient. Fixes open-mpi#8434 Signed-off-by: Nathan Hjelm <hjelmn@google.com> (cherry picked from commit 8040d05)

Well, it appears git does put a limit on the branch name. |
