[MPICH] MPICH2 v1.02 in heterogeneous enviroment

[Kenneth Rempe]

I'm using MPICH2 v1.02 with IBM AIX 5.2 and Red Hat Linux. My program 
works fine
if I just run on Linux machines or just IBM machines but fails with the 
following message when
trying to run on both IBM and Linux at the same time.

Fatal error in MPI_Comm_spawn: Internal MPI error!, error stack:
MPI_Comm_spawn(128):

Is it possible to use MPICH2 in a heterogeneous environment?

Thanks.
