Re: MPI & mpirun freezing

I have a cluster consisting of 11 computational nodes, and 1 head

P3. The computational nodes are technically homogeneous, but they all
have the same amount of RAM, same processor, same network card, etc.
My problem is thus: My first four nodes are of one type, the last
seven of another. Whenever I mpirun a simple program (the pi example
program, or even just a hello world program), it basically becomes
nonresponsive if I request more than four processes. Any ideas?
Which MPI implementation (mpich, lam)? Which version? Which Debian
distribution (Woody, Potato, Sarge, Sid)? Does passwordless rsh work to
all nodes?
Need a bit more information to be helpful.
Also, html emails to Debian lists are generally frowned upon.
