-parallel Intel compiler option

[Satish Balay]

nope - PETSc uses MPI for parallelism internally - so using the
additional compiler directive is not required. It mignt work - but it
is not appropriate. [we never tested this mode]

If you use this option - you'll need to understand what exactly it
means [in this context of MPI etc.. ] - and how you want to control
various issues involved in this mode. You can check out literature [or
google for] 'Mixing MPI and OpenMP'.
