Please keep the discuss at mpich mailing list cc'ed.

Yes, this is a problem.  Is one of your machines actually a 32-bit
machine or did you just install a 32-bit OS on a 64-bit machine?  If
it's the latter, you could reinstall a 64-bit OS.

If you can't do that, another option is to build MPICH in 32-bit mode on
both machines by passing CFLAGS=-m32 to configure on the 64-bit machine.
 This will require that you have the right 32-bit libraries installed on
your 64-bit machine (such as the 32-bit libc library).  This option is
typically for expert users, and is not a recommended option for most users.
