OK...this is beyond remote debugging. I don't know why gcc (I think
that is the compiler you specified) would be creating code with illegal
instructions. Does the serial code for nab work? "mpinab" is an
executable that only differs in a tiny way from "nab" (e.g. by adding
mpi_init() calls to the code it outputs). Make sure you are building
mpinab in a way that is a similar as possible to the way you build nab.
Be sure that you don't have any object files lying around from some other
compiler. You'll probably have to compile and run mpinab in a debugger to
flag down the origin of the illegal instruction.
