PETSc is an MPI program, so you run it in parallel the same way you run any
MPI program. There
are many MPI tutorials on the web, and the way to do it depends on exactly
how things are setup
on your system, so I can't just tell you.

Normally, the system administrator of a system installs MPI and you have an
'mpiexec' executable
for running in parallel. Is this missing?

  Thanks,

experiments is infinitely more interesting than any results to which their
experiments lead.
