Michael,

If your script executes qsub to queue out your job, then #$ -V will have no
effect.  This only works for a script that is actually submitted by qsub to
the grid.

The cluster is down at the moment so cannot check this, but I've had #$ -V
at the top of my qsub script. Is this the correct place or does it have to
be placed once the env vars have been set in the script?

I was wondering if it's anything to do with mpich1...

More once the cluster is back
Ta, Michael
