 More fun. Parallel jobs can be submitted over ethernet interconnects but will not achieve the performance of Infiniband interconnects ofcourse. ​ OpenMPI is a nice MPI flavor because software compiled with it automatically detects if the host has an HCA card or not and will allocate the appropriate libraries.
