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

lam being mostly just a previous version of lam, and I think inheriting

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