[MPICH] grid computing, passing envirnoment variables using mpirun

[Rajeev Thakur]

In MPICH-1, I believe the environment variables have to be defined in your
.cshrc or .login startup files (on each node where the program runs). In
MPICH2, you can pass environment variables as parameters to mpiexec as
described in the Users Guide.
