Important Note:

If you're using Mac OS X 10.3 with MPICH-GM, you will need the following patch.
For AIX, MPICH-GM should only be used in single-threaded applications.
The APAR IY66938 patch must be applied to AIX 5.3 when running MPICH-GM on AIX 5.3. This patch can be obtained by searching for IY66938 on the http://www.ibm.com website.

MPICH-GM has been tested with the following compilers:

Linux -- Gnu compilers, PGI5 compilers, Intel 8.x compilers, and IBM XL compilers.
Solaris -- SunPro/Forte C compiler for UltraSPARC, and Gnu compilers for x86.
AIX -- IBM XL compilers.
Mac OS X -- Gnu compilers and IBM XL compilers.

on the supported OS versions specified on the GM Download webpage.

Performance graphs for MPICH-GM are available.

Installation information:

Installation instructions caveats can be found in the README-mpich-gm in the distribution tar file.
MPICH-GM 1.2.7p1..20 is based on MPICH-1.2.7p1. Refer to the Patches for MPICH webpage for bug fixes to the generic MPICH code since that release.
Directions for running an MPI program using MPICH-GM on Windows can be found on the FAQ.
MPICH-GM does not support heterogeneity. Refer to the following FAQ entry for details.
This release of MPICH-GM is designed for use with GM-2 and GM-1.
The mpicc default is now to use a shared library, use -noshlib or MPICH_USE_SHLIB=no to revert to static linking.
If you are using GM-2, you must use MPICH-GM 1.2.5..10 or later.
For documentation on MPD support, customers with experience with MPICH ch_p4mpd will find the MPD support in ch_gm completely identical (using mpirun.mpd instead of mpirun). There are several entries in the Myricom FAQ pertaining to MPD support in MPICH-GM.
For AIX, MPICH-GM is distributed as a source RPM file (SRPM) and should be built and installed with the "rpm" command. Refer to the following FAQ entry for details.
