MYROW   (local input)                 const int
        On entry,  MYROW  specifies the row coordinate of the process
        whose rank is to be determined. MYROW must be greater than or
        equal to zero and less than NPROW.
MYCOL   (local input)                 const int
        On entry,  MYCOL  specifies  the  column  coordinate  of  the
