it's more convienent to have mpich2 installed to the same place on all
nodes, but as long as you set up your environment variables correctly
it shouldn't matter.
As the MPICH2 README points out (7. Add the bin subdirectory of the
installation directory to your path:), on your master you need to add
/usr/local/bin to your path (well, actually, it's already there) and
on the slaves add /usr/local/mpich2/bin to your path.
You'll have to add this to an init script that's sourced whenever a
non-login shell is started. (.zshenv, .bashrc, .profile... depends on
We should continue this discussion on mpich-discuss at mcs.anl.gov if you
continue to have difficulty.
