I installed MPICH on a RS6000 workstation cluster,having a shared file system.
I downloaded it  at / and later set PREFIX=/usr/MPI .This was done as root.
I am able to run MPI programs from my user account. But when I su to root,
the I get a message "permission denied". On the hosts I run, I have a
$HOME/.rhosts for both root and my userid,populated with the names of the hosts.
In fact the .rhosts in my userid is identical to the one in root.
tstmachines succeds in case I ma logged is as my userid but fails when I am root.
Can anybody spot where I went wrong?
