Dear all, I recompiled Open MPI 1.7.5 a couple of time, I am sure I have been selected openib. However I have some doubts because this message
-------------------------------------------------------------------------- [[28098,1],8]: A high-performance Open MPI point-to-point messaging module was unable to find any relevant network interfaces: Module: usNIC Host: tesla79 Another transport will be used instead, although this may result in lower performance. -------------------------------------------------------------------------- keeps popping up. I am really worried there might be a degradation of performance because of this warning. Any clue about where it came from and how I can let it disappear?
