[mvapich-discuss] Query related to running MVAPICH over OFED

[Dhabaleswar Panda]

On your system, are you able to run basic uDAPL-level tests with OFED
1.1-uDAPL installation? It will be good if you try this first to make
sure that uDAPL installation is correct. Then you can put MPI on top
of this and carry out MPI-level tests and performance evaluation.
