> Well, does `mpiexec` point to the correct one?
I don't really get this. I only installed one and only one OpenMPI on the node. There shouldn't have another 'mpiexec' on the system.It's worthy to mention that every node is deployed from a master image. So everything is exactly the same except IP and DNS name.

What about:pwbcad@sgeqexec01:~$ ompi_info | grep gridMCA ras: gridengine (MCA v2.0, API v2.0, Component v1.4.1)Is there any location I can find a more meaningful OpenMPI log?I will try to install openmpi 1.4.3 and see if that works.I want to confirm one more thing: does SGE's master host need to have OpenMPI installed? Is it relevant?Many thanks ReutiDerrick_______________________________________________
