Thanks for the feedback so far.
Now how about MPI coexistance?
LAM-MPI wants PATH set in .bashrc or some similar
startup file. If memory serves, that was also the method
used by Mpich(1.x). MPICH2 at least seems to have a way
around this since mpdboot works with no twiddling of
startup files on the remote nodes.
So then, if LAM-MPI and MPICH(1.x) both want PATH set to point
to their own binary directories at login, from a single account,
how does one run program A that wants MPICH and program B that wants
LAM-MPI? Hopefully there's something better than "change the
.bashrc file before each run"!
