[mpich-discuss] MPI profiling

[Anthony Chan]

mpicc in your path is still mpich2, but it is likely an older
version, do /usr/bin/mpich2version for the version.

The mpich2-1.4 that you just built is installed in /home/balaji/mpich2-install.
Link your MPI benchmark using fullpath to mpicc as follows

/home/balaji/mpich2-install/bin/mpicc -mpe=mpilog -o homb.ex -O3 -fopenmp src/homb.c
