MPICH-MX and MPICH2-MX Software

MPICH-MX is a port of MPICH1 on top of MX (ch_mx), and MPICH2-MX is a port of MPICH2 on top of MX (ch_mx).

Since MX-10G and MX-2G are fully compatible at the API and application level, the MPICH-MX and MPICH2-MX middleware can be used with both MX-10G and MX-2G.

MPICH-MX and MPICH2-MX are distributed in source form. MSI installers for Windows are also available.

Note:

For production environments, we recommend MPICH-MX instead of MPICH2-MX.
This pre-release of MPICH2-MX matches all of the functionality of MPICH-MX, but does not yet implement the following MPI-2 functionality:
- Dynamic process management (connect/accept, comm_spawn[_multiple])
- One-sided operations
- MPI_THREAD_MULTIPLE support
We are in the process of adding one-sided functions in the MX API, following the ARMCI semantic. As soon as this support has been added to the MX API, we will have one-sided communication in MPICH2-MX.

MPICH-MX has been tested with the following compilers:

Linux -- Gnu compilers, PGI5 compilers, Intel 8.x compilers.
Mac OS X -- Gnu compilers and IBM XL compilers.

on the supported OS versions specified on the MX-10G Download webpage and MX-2G Download webpage.

Performance graphs for MPICH-MX over MX-10G and MPICH-MX over MX-2G are available. To obtain the maximum bandwidth performance with MPICH-MX, refer to the following FAQ entry for details.

Installation information:

Installation instructions can be found in the respective README-mpich-mx or README-mpich2-mx in the distribution tar file.
MPICH-MX and MPICH2-MX do not support heterogeneity. Refer to the following FAQ entry for details.
MPICH-MX 1.2.7..7 is based on MPICH 1.2.7, and MPICH2-MX 1.0.7..2 is based on MPICH2 1.0.7. Refer to the Patches for MPICH1 webpage for bug fixes to the generic MPICH1 code since that release. Refer to the RELEASE_NOTES for known deficiences in the MPICH2 code.
To obtain the maximum bandwidth performance with MPICH-MX and MPICH2-MX, refer to the following FAQ entry for details.
IBM XL compilers are not yet supported on Mac OS X 10.4. Refer to the following FAQ entry for details.
If you're using Mac OS X, 64-bit MPICH-MX shared libs are supported starting with MPICH-MX 1.2.7..2.
For documentation on MPD support, customers with experience with MPICH ch_p4mpd will find the MPD support in ch_mx completely identical (using mpirun.mpd instead of mpirun). There are several entries in the Myricom FAQ pertaining to MPD support in MPICH-GM which also apply to MPICH-MX.
