You can run sequentially with just a single MPI process (-n 1). If you need to run without MPI whatsoever, you’ll need to have a separate PETSc installation which was configured --with-mpi=0 In both cases, the same user-code will run, i.e., all PETSc examples available with the sources will work (though some are designed purely for parallel experiments and may error out early on purpose).
