[MPICH] error information

[Anthony Chan]

Jazz has mpich2 prebuilt with pgi and intel compilers.

ls -d /soft/apps/packages/mpich2*
/soft/apps/packages/mpich2-1.0.1-intel-8.1/
/soft/apps/packages/mpich2-gm-1.0.1-pgi-5.2/
/soft/apps/packages/mpich2-ip-1.0.1-pgi-5.2/

You could build mpich2 with gcc yourself.  If you need to use myrinet,
you can build mpich2 with gasnet support.
