  *  Purpose
  *  =======
  *
  *  PDSYMM  performs one of the matrix-matrix operations
  *
  *     sub( C ) := alpha*sub( A )*sub( B ) + beta*sub( C ),
  *
  *  or
  *
  *     sub( C ) := alpha*sub( B )*sub( A ) + beta*sub( C ),
  *
  *  where
  *
  *     sub( C ) denotes C(IC:IC+M-1,JC:JC+N-1),
  *
  *     sub( A ) denotes A(IA:IA+M-1,JA:JA+M-1)  if SIDE = 'L',
  *                      A(IA:IA+N-1,JA:JA+N-1)  if SIDE = 'R', and,
  *
  *     sub( B ) denotes B(IB:IB+M-1,JB:JB+N-1).
  *
  *  Alpha  and  beta  are scalars,  sub( A ) is a symmetric submatrix and
  *  sub( B ) and sub( C ) are m by n submatrices.

  *  Notes
  *  =====
  *
  *  A description  vector  is associated with each 2D block-cyclicly dis-
  *  tributed matrix.  This  vector  stores  the  information  required to
  *  establish the  mapping  between a  matrix entry and its corresponding
  *  process and memory location.
  *
  *  In  the  following  comments,   the character _  should  be  read  as
  *  "of  the  distributed  matrix".  Let  A  be a generic term for any 2D
  *  block cyclicly distributed matrix.  Its description vector is DESC_A:
  *
  *  NOTATION         STORED IN       EXPLANATION
  *  ---------------- --------------- ------------------------------------

  *                                   A  is  distributed over. The context
  *                                   itself  is  global,  but  the handle
  *                                   (the integer value) may vary.
  *  M_A     (global) DESCA[ M_     ] The  number of rows in the distribu-
  *                                   ted matrix A, M_A >= 0.

  *  INB_A   (global) DESCA[ INB_   ] The  number  of columns of the upper
  *                                   left   block   of   the  matrix   A,

  *  MB_A    (global) DESCA[ MB_    ] The blocking factor used to  distri-
  *                                   bute the last  M_A-IMB_A  rows of A,
  *                                   MB_A > 0.
  *  NB_A    (global) DESCA[ NB_    ] The blocking factor used to  distri-
  *                                   bute the last  N_A-INB_A  columns of
  *                                   A, NB_A > 0.
  *  RSRC_A  (global) DESCA[ RSRC_  ] The process row over which the first
  *                                   row of the matrix  A is distributed,
  *                                   NPROW > RSRC_A >= 0.
  *  CSRC_A  (global) DESCA[ CSRC_  ] The  process column  over  which the
  *                                   first column of  A  is  distributed.
  *                                   NPCOL > CSRC_A >= 0.
  *  LLD_A   (local)  DESCA[ LLD_   ] The  leading dimension  of the local
  *                                   array  storing  the  local blocks of
  *                                   the distributed matrix A,
  *                                   IF( Lc( 1, N_A ) > 0 )
  *                                      LLD_A >= MAX( 1, Lr( 1, M_A ) )
  *                                   ELSE
  *                                      LLD_A >= 1.
  *
  *  Let K be the number of  rows of a matrix A starting at the global in-
  *  dex IA,i.e, A( IA:IA+K-1, : ). Lr( IA, K ) denotes the number of rows
  *  that the process of row coordinate MYROW ( 0 <= MYROW < NPROW ) would
  *  receive if these K rows were distributed over NPROW processes.  If  K
  *  is the number of columns of a matrix  A  starting at the global index
  *  JA, i.e, A( :, JA:JA+K-1, : ), Lc( JA, K ) denotes the number  of co-
  *  lumns that the process MYCOL ( 0 <= MYCOL < NPCOL ) would  receive if
  *  these K columns were distributed over NPCOL processes.
  *
  *  The values of Lr() and Lc() may be determined via a call to the func-
  *  tion PB_Cnumroc:
  *  Lr( IA, K ) = PB_Cnumroc( K, IA, IMB_A, MB_A, MYROW, RSRC_A, NPROW )
  *  Lc( JA, K ) = PB_Cnumroc( K, JA, INB_A, NB_A, MYCOL, CSRC_A, NPCOL )
