[Beowulf] MPICH on heterogeneous (i386 + x86_64) cluster

Have anyone try running MPI programs with MPICH on heterogeneous cluster
with both i386 and x86_64 machines? Can I use a i386 binary on the i386
machines while use a x86_64 binary on the x86_64 machines for the same
MPI program? I thought they can communicate before but it seems that I
was wrong because I got error in the testing.

Have anyone try that before?

Best regards,
John Lau
