A question about parallel computation

[Satish Balay]

Perhaps you are using the wrong mpiexec or mpirun. You'll have to use
the correspond mpiexec from MPI you've used to build PETSc.

Or if the MPI has special instruction on usage - you should follow
that [for ex: some clusters require extra options to mpiexec ]
