but what have you tried?  I would guess that this is a simple rsh config
problem, nothing to do with mpich.

but why do you think the problem lies with mpich?

lam being mostly just a previous version of lam, and I think inheriting
lam's agent-based process-starting, no?

personally, I'm pretty convinced that MPI implementations should stay
out of the jobstarter business, and go with straight agentless (ssh-based)
job spawning.
