PROGRAM PCBLA2TIM
*
* -- PBLAS testing driver (version 1.5) --
* University of Tennessee, Knoxville, Oak Ridge National Laboratory,
* and University of California, Berkeley.
* May 1, 1997
*
* Purpose
* ========
*
* PCBLA2TIM is the main timer program for the COMPLEX
* PBLAS Level 2 routines.
*
* The program must be driven by a short data file. An annotated
* example of a data file can be obtained by deleting the first 3
* characters from the following 49 lines:
* 'ScaLAPACK, Version 2.0, Level 2 PBLAS timer input file'
* 'Intel iPSC/860 hypercube, gamma model.'
* 'PCBLATIM2.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
* (1.0E0, 0.0E0) value of ALPHA
* (1.0E0, 0.0E0) value of BETA
* 2 number of tests problems
* 'U' 'L' values of UPLO
* 'N' 'T' values of TRANS
* 'N' 'U' values of DIAG
* 3 4 values of M
* 3 4 values of N
* 6 10 values of M_A
* 6 10 values of N_A
* 2 5 values of MB_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_X
* 6 10 values of N_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 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
* PCGEMV T put F for no test in the same column
* PCHEMV T put F for no test in the same column
* PCTRMV T put F for no test in the same column
* PCTRSV T put F for no test in the same column
* PCGERU T put F for no test in the same column
* PCGERC T put F for no test in the same column
* PCHER T put F for no test in the same column
* PCHER2 T put F for no test in the same column
*
* Internal Parameters
* ===================
*
* TOTMEM INTEGER, default = 2000000
* TOTMEM is a machine-specific parameter indicating the
* maximum amount of available memory 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.
*
* INTGSZ INTEGER, default = 4 bytes.
* CPLXSZ INTEGER, default = 8 bytes.
* INTGSZ, REALSZ and CPLXSZ indicate the length in bytes on
* the given platform for an integer, a single precision real
* and a single precision complex.
* MEM COMPLEX array, dimension ( TOTMEM / CPLXSZ )
*
* All arrays used by SCALAPACK routines are allocated from
* this array and referenced by pointers. The integer IPA,
* for example, is a pointer to the starting element of MEM for
* the matrix A.
