For sake of code developing, I would like to test my mpi program on a
desktop. The program will use PETSc, a parallel numerical library. Is that
possible for me to run the code with:

"mpirun -np 4 mmox" even I am running it on my desktop with one CPU? Shall I
generate a machine file looks like the following:

localhost

localhost

localhost

localhost

If I want to use 4 CPUs.

Thank you guys.

Zhang
