| 1 | Hi all (again) - |
| 2 | |
| 3 | I just came to the realization that OpenMPI does not support a multithreaded |
| 4 | model with infiniband. I am looking into the openib-mvapich2, as mvapich |
| 5 | appears to support both infiniband and multithreading simultaneously. |
| 6 | Unfortunately, I'm getting a blockage saying that it can't be used with the |
| 7 | openib-userspace package. |

| 9 | Does anyone know of an easy way to resolve this? |
| 10 | Thanks! |
