Hi Tyler:
As far as I know, if you
want MPICH to use PGI instead of gcc, you'll need to re-compile it (you can get
the source from the SRPM). The MPICH which came with OSCAR is compiled
with gcc, and thus the name of the package is "mpich-ch_p4-gcc".
I would suggest you
compile it with "/opt/mpich-pgi-1.2.7" as the prefix (or something similiar) and
once you successfully build it, you can push this directory out to all your
compute nodes. You probably want to play with switcher so that you can
switch between different implementations of MPI (man switcher).
It would be great if you
can write up a receipe on how to build MPICH-PGI under OSCAR - we'll put it up
in our Wiki.
P.S. Perhaps we should
talk to the PGI folks about creating a package again...
Cheers,
Bernard
