Hallo,

it should be possible to run an other program on every workstation.
That is described for different architectures in the "Installation Guide
to
mpich" (side 27).

An other idea with SPMD (master-slaves):
- master asks you where to start which "program" and sends a message
- every slaves receive his message and calls a different function
- whith dynamic linking it looks nearly like a MPMD-program

Any questions? Send me a mail.

Bye,
 Christoph
