I am using mpich.  Suppose that my mpi program (mycode) reads an
environment variable FOO.  If I do:

node0> setenv FOO 10
node0> mpirun -np 4 mycode

then the only version of "mycode" which has access to the
value of FOO is the one running on node0.

Is there a way I can export environment variables to all
the machines?  Note that I have replaced rsh in mpirun with
secure shell (ssh).

Please copy any replies to ballen@dirac.phys.uwm.edu.  Thanks!
