*  Purpose
*  =======
*
*  INDXG2P computes the process coordinate which posseses the entry of a
*  distributed matrix specified by a global index INDXGLOB.
*
*  Arguments
*  =========
*
*  INDXGLOB  (global input) INTEGER
*            The global index of the element.
*
*  NB        (global input) INTEGER
*            Block size, size of the blocks the distributed matrix is
*            split into.
*
*  IPROC     (local dummy) INTEGER
*            Dummy argument in this case in order to unify the calling
*            sequence of the tool-routines.
*
*  ISRCPROC  (global input) INTEGER
*            The coordinate of the process that possesses the first
*            row/column of the distributed matrix.
*
*  NPROCS    (global input) INTEGER
*            The total number processes over which the matrix is
*            distributed.
