Good day,

The simplest method I can think of is to load MPI onto your
uniprocessor, and then when you execute your code, make sure the
machinefile has only the name of the local machine in it.  Then,
regardless of how  many processes you specify, all will be placed on
your uniprocessor.  You won't see any speedup, natch (in fact, you'll
probably see slow-down due to overhead), but you'll be able to
validate the execution of your code. 

Here's where you can download the MPICH distribution of MPI:

Take care,
