PROGRAM PCBLA3TIM
*
* -- PBLAS timing driver (version 2.0) --
* University of Tennessee, Knoxville, Oak Ridge National Laboratory,
* and University of California, Berkeley.
* April 1, 1998
*
* Purpose
* =======
*
* PCBLA3TIM is the main timing program for the Level 3 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 59 lines:
* 'Level 3 PBLAS, Timing input file'
* 'Intel iPSC/860 hypercube, gamma model.'
* 'PCBLAS3TIM.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
* (1.0E0, 0.0E0) value of ALPHA
* (1.0E0, 0.0E0) value of BETA
* 2 number of tests problems
* 'N' 'U' values of DIAG
* 'L' 'R' values of SIDE
* 'N' 'T' values of TRANSA
* 'N' 'T' values of TRANSB
* 'U' 'L' values of UPLO
* 3 4 values of M
* 3 4 values of N
* 3 4 values of K
* 6 10 values of M_A
* 6 10 values of N_A
* 2 5 values of IMB_A

* 2 5 values of NB_A
* 0 1 values of RSRC_A
* 0 0 values of CSRC_A
* 1 1 values of IA
* 1 1 values of JA
* 6 10 values of M_B
* 6 10 values of N_B

* 2 5 values of INB_C
* 2 5 values of MB_C
* 2 5 values of NB_C
* 0 1 values of RSRC_C
* 0 0 values of CSRC_C
* 1 1 values of IC
* 1 1 values of JC
* PCGEMM T put F for no test in the same column
* PCSYMM T put F for no test in the same column

* PCTRMM T put F for no test in the same column
* PCTRSM T put F for no test in the same column
* PCGEADD T put F for no test in the same column
* PCTRADD 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.
*
* REALSZ INTEGER
* CPLXSZ INTEGER
* REALSZ and CPLXSZ indicate the length in bytes on the given
* platform for a single precision real and a single precision
* complex. By default, REALSZ is set to four and CPLXSZ is set
* to eight.
*
* MEM COMPLEX array
* MEM is an array of dimension TOTMEM / CPLXSZ.
* 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.
