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

[Kekatpure, Rohan Deodatta (-EXP)]

Thanks Gustavo. I found out the default installation on OX-S too. I would like to use my MPICH with fortran support (I have gfortran installed). Could you tell me how to modify the PATH in order to use my version of MPICH? My MPICH2 is installed in  /usr/local/hpc/mpich/install.

Thanks 
Rohan
