hi,

i had similar problems recently. david told me that gromacs doesn't work
well with mpich and recommended using lam instead (try to search the
archives to see the relevant posts).
i couldn't run mdrun under mpich on more than 4 processors. if 5 were
used, only the last one was really working...

regards,
