Hi Kameyama and SCore list,

Thanks for your suggestion (below). I have added the option nfsvers=3 to
the mount options on all compute nodes, and remounted the shared
partition:

snowdon.leeds.ac.uk:/scratch on /scratch type nfs
(rw,noac,nfsvers=3,addr=192.168.1.254)

But we are still having the same problem:

<0:0> SCORE: 32 nodes (16x2) ready.  File locking failed in
ADIOI_Set_lock. If the file system is NFS, you need to use NFS version 3
and mount the directory with the 'noac' option (no attribute caching).  
[0] MPI Abort by user Aborting program !  [0] Aborting program!

Streamline Computing recently did a SCore upgrade from 5.3 to 5.4 for
us. The code was working before the upgrade, there were no such complaints
from SCore about MPI-IO. I mention it just in case it helps you diagnose
the problem.

Thanks in advance for your help
Mark
