I'm not sure I understand what's actually happened here. I'm running
IMB on an HP superdome, just comparing the PingPong benchmark
Max ~ 700-800MB/sec
-mca btl self,sm - Max ~ 125-150MB/sec
-mca btl self,tcp - Max ~ 500-550MB/sec
Is this behavior expected? Are there any tunables to get the OpenMPI
sockets up near HP-MPI?
