      PROGRAM PZBLA2TIM
*
*  -- PBLAS timing driver (version 2.0) --
*     University of Tennessee, Knoxville, Oak Ridge National Laboratory,
*     and University of California, Berkeley.
*     April 1, 1998
*
*  Purpose
*  =======
*
*  PZBLA2TIM  is the main timing program for the Level 2 PBLAS routines.
*
*  The program must be driven by a short data file.  An  annotated exam-
*  ple of a data file can be obtained by deleting the first 3 characters
*  from the following 56 lines:
*  'Level 2 PBLAS, Timing input file'
*  'Intel iPSC/860 hypercube, gamma model.'
*  'PZBLAS2TIM.SUMM'   output file name (if any)
*  6       device out
*  10              value of the logical computational blocksize NB
*  1               number of process grids (ordered pairs of P & Q)
*  2 2 1 4 2 3 8   values of P
*  2 2 4 1 3 2 1   values of Q
*  (1.0D0, 0.0D0)  value of ALPHA

*  Internal Parameters
*  ===================
*
*  TOTMEM  INTEGER
*          TOTMEM  is  a machine-specific parameter indicating the maxi-
*          mum  amount  of  available  memory per  process in bytes. The
*          user  should  customize TOTMEM to his  platform.  Remember to
*          leave  room  in  memory  for the  operating system, the BLACS
*          buffer, etc.  For  example,  on  a system with 8 MB of memory
*          per process (e.g., one processor  on an Intel iPSC/860),  the
*          parameters we use are TOTMEM=6200000  (leaving 1.8 MB for OS,
*          code, BLACS buffer, etc).  However,  for PVM,  we usually set
*          TOTMEM = 2000000.  Some experimenting  with the maximum value
*          of TOTMEM may be required. By default, TOTMEM is 2000000.
*
*  DBLESZ  INTEGER
*  ZPLXSZ  INTEGER
*          DBLESZ  and  ZPLXSZ indicate the length in bytes on the given
*          platform  for a double  precision real and a double precision
*          complex. By default, DBLESZ is set to eight and ZPLXSZ is set
*          to sixteen.
*
*  MEM     COMPLEX*16 array
*          MEM is an array of dimension TOTMEM / ZPLXSZ.
*          All arrays used by SCALAPACK routines are allocated from this
*          array MEM and referenced by pointers. The  integer  IPA,  for
*          example, is a pointer to the starting element of MEM for  the
*          matrix A.
