Closed pimpleFoam uses non-native collectives

    In e.g. pimpleFoam it still uses the following non-native collectives:

    • Pstream::scatter inside fileMonitor::updateStates (only if runTimeModifiable)
    • Foam::gMax (from Foam::reduce) in CourantNo determination
    • bound() from RASModels::kEpsilon
    • reduce<bool, Foam::andOp > from p.needReference()

    (done by adding a error::printStack(Pout) to UIPstream::read)

    These could optionally be converted to native MPI calls.
