I am not familiar with OPA but I can point out couple of issues here:

1 - PAMI installed on the system which seems to be 1.2, "may not" be compatible with MPICH3 code. MPICH3 is only supported on 1.4 and above and only for Linux 2 - --with-file-system=bg+bglockless is definitely the wrong option for this machine. I would try nfs+ufs

If this machine has GPFS, then use the new 3.x style: --with-file-system=gpfs:PE ==rob _______________________________________________ ibm mailing list [email protected] https://lists.mpich.org/mailman/listinfo/ibm
