PROGRAM PDBLA1TIM
*
* -- PBLAS timing driver (version 2.0) --
* University of Tennessee, Knoxville, Oak Ridge National Laboratory,
* and University of California, Berkeley.
* April 1, 1998
*
* Purpose
* =======
*
* PDBLA1TIM is the main timing program for the Level 1 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 40 lines:
* 'Level 1 PBLAS, Timing input file'
* 'Intel iPSC/860 hypercube, gamma model.'
* 'PDBLAS1TIM.SUMM' output file name (if any)
* 6 device out
* 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 value of ALPHA
* 2 number of tests problems
* 3 4 values of N
* 6 10 values of M_X
* 6 10 values of N_X
* 2 5 values of IMB_X
* 2 5 values of INB_X
* 2 5 values of MB_X
* 2 5 values of NB_X
* 0 1 values of RSRC_X
* 0 0 values of CSRC_X
* 1 1 values of IX
* 1 1 values of JX
* 1 1 values of INCX
* 6 10 values of M_Y
* 6 10 values of N_Y
* 2 5 values of IMB_Y
* 2 5 values of INB_Y
* 2 5 values of MB_Y
* 2 5 values of NB_Y
* 0 1 values of RSRC_Y
* 0 0 values of CSRC_Y
* 1 1 values of IY
* 1 1 values of JY
* 6 1 values of INCY
* PDSWAP T put F for no test in the same column
* PDSCAL T put F for no test in the same column
* PDCOPY T put F for no test in the same column
* PDAXPY T put F for no test in the same column
* PDDOT T put F for no test in the same column
* PDNRM2 T put F for no test in the same column
* PDASUM T put F for no test in the same column
* PDAMAX T put F for no test in the same column
*
* 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
* DBLESZ indicates the length in bytes on the given platform
* for a double precision real. By default, DBLESZ is set to
* eight.
*
* MEM DOUBLE PRECISION array
* MEM is an array of dimension TOTMEM / DBLESZ.
* 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.

* Antoine Petitet, University of Tennessee, Knoxville 37996, USA.
