11 PROGRAM pdbla1tim
12*
13* -- PBLAS timing driver (version 2.0.2) --
14* Univ. of Tennessee, Univ. of California Berkeley, Univ. of Colorado Denver
15* May 1 2012
16*
17* Purpose
18* =======
19*
20* PDBLA1TIM is the main timing program for the Level 1 PBLAS routines.
21*
22* The program must be driven by a short data file. An annotated exam-
23* ple of a data file can be obtained by deleting the first 3 characters
24* from the following 40 lines:
25* 'Level 1 PBLAS, Timing input file'
26* 'Intel iPSC/860 hypercube, gamma model.'
27* 'PDBLAS1TIM.SUMM' output file name (if any)
28* 6 device out
29* 1 number of process grids (ordered pairs of P & Q)
30* 2 2 1 4 2 3 8 values of P
31* 2 2 4 1 3 2 1 values of Q
32* 1.0D0 value of ALPHA
33* 2 number of tests problems
34* 3 4 values of N
35* 6 10 values of M_X
36* 6 10 values of N_X
37* 2 5 values of IMB_X
38* 2 5 values of INB_X
39* 2 5 values of MB_X
40* 2 5 values of NB_X
41* 0 1 values of RSRC_X
42* 0 0 values of CSRC_X
43* 1 1 values of IX

45* 1 1 values of INCX
46* 6 10 values of M_Y
47* 6 10 values of N_Y
48* 2 5 values of IMB_Y
49* 2 5 values of INB_Y

66* Internal Parameters
67* ===================
68*
69* TOTMEM INTEGER
70* TOTMEM is a machine-specific parameter indicating the maxi-
71* mum amount of available memory per process in bytes. The
72* user should customize TOTMEM to his platform. Remember to
73* leave room in memory for the operating system, the BLACS
74* buffer, etc. For example, on a system with 8 MB of memory
75* per process (e.g., one processor on an Intel iPSC/860), the
76* parameters we use are TOTMEM=6200000 (leaving 1.8 MB for OS,
77* code, BLACS buffer, etc). However, for PVM, we usually set
78* TOTMEM = 2000000. Some experimenting with the maximum value
79* of TOTMEM may be required. By default, TOTMEM is 2000000.
80*
81* DBLESZ INTEGER
82* DBLESZ indicates the length in bytes on the given platform
83* for a double precision real. By default, DBLESZ is set to
84* eight.
85*
86* MEM DOUBLE PRECISION array
87* MEM is an array of dimension TOTMEM / DBLESZ.
88* All arrays used by SCALAPACK routines are allocated from this
89* array MEM and referenced by pointers. The integer IPA, for
90* example, is a pointer to the starting element of MEM for the
91* matrix A.
