Since your working directory and the Foam installation have to be visible from all the machines, you can just log into one of the cluster nodes and start the job from there.

If this is a problem because of some batch queing system like pbs, you should submit the job via this system. I can provide an example script for pbs if required.

Thanks for your help.

I have just got help from my admin. I use 'rsh node#' to a empty node and run my case from there.

Thanks.
