        ! REMARK-1: the interface of PART_VERTS and PART_FACES, needed for
        ! allocating the PSBLAS descriptors, is fixed by PARTS.FH, in the
        ! PSBLAS library. Hence, the only way for carrying the C2V and C2F
        ! variables inside the two procedures is to handle them as public
        ! shared variables.

        ! REMARK-2: PV could be initialized equal to any negative value.
        ! The choice of NVERTS and NFACES is only for avoiding the detection
        ! of an unused variable.
