[mpich-discuss] [EXTERNAL] Re: Modifying ssh calls for MPICH2

[Gustavo Correa]

Hi Rohan

A simple way to do it,
if you are using bash, you could add a line similar to this to 
your .profile file in /Users/rohan [i.e. in your home directory]:

export PATH=/usr/local/hpc/mpich/install/bin:${PATH}

Then open a new terminal and do 'which mpicc', 'which mpirun' to see if it points to the
MPICH2 components.

I hope this helps,
Gus Correa
