[MPICH] error information

[Wei-keng Liao]

I was told by Jazz system support last week that the MPICH compiled with 
gcc and GM is in /soft/apps/packages/mpich-gm-1.2.6..13b-gcc-3.2.3-1/bin

: Just add the softenv key "@all-mpich_gm-gcc3.2.3" before the"@default"
: line in your ~/.soft file (and then type "resoft" or logout and back
: into jazz), this will place the gcc MPI environment inyour path ahead of 
: the system default intel one.
