[MPICH] Master tied to one node

[Alok G Singh]

Is it possible for the master task (taskid 0) to be tied to a specified (in some way, IP address, hostname) processor ? From some preliminary experiments that I did, the master always runs on the node where the job is fired (the submit node is also part of the cluster). Is this always the case or is it just coincidence ?

What is required is to make the master process run only a special type of node (one which has local storage, in this case). Any help would be much appreciated.

TIA,
Alok
