Disable non-blocking collectives with OpenMPI #209

Closed mirenradia closed 2 years ago

mirenradia commented 2 years ago

This is a somewhat unsatisfactory workaround that resolves #208. In an ideal world, we'd figure out the cause of this problem properly but I think this is acceptable since OpenMPI is rarely the most performant MPI implemtation nor the only one available on most clusters.
