20 * Purpose
21 * =======
22 *
23 * PCSEPRREQ performs one request from the input file 'SEPR.dat'
24 * A request is the cross product of the specifications in the
25 * input file. It prints one line per test.
26 *
27 * Arguments
28 * =========
29 *
30 * NIN (local input) INTEGER
31 * The unit number for the input file 'SEPR.dat'
32 *
33 * MEM (local input ) COMPLEX ARRAY, dimension MEMSIZE
34 * Array encompassing the available single precision memory
35 *
36 * MEMSIZE (local input) INTEGER
37 * Size of MEM array
38 *
39 * NOUT (local input) INTEGER
40 * The unit number for output file.
41 * NOUT = 6, output to screen,
42 * NOUT = 0, output to stderr.
43 * NOUT = 13, output to file, divide thresh by 10
44 * NOUT = 14, output to file, divide thresh by 20
45 * Only used on node 0.
46 * NOUT = 13, 14 allow the threshold to be tighter for our
47 * internal testing which means that when a user reports
48 * a threshold error, it is more likely to be significant.
49 *
50 * ISEED (global input/output) INTEGER array, dimension 4
51 * Random number generator seed
52 *
53 * NTESTS (global input/output) INTEGER
54 * NTESTS = NTESTS + tests requested
55 *
56 * NSKIPPED (global input/output) INTEGER
57 * NSKIPPED = NSKIPPED + tests skipped
58 *
59 * NNOCHECK (global input/output) INTEGER
60 * NNOCHECK = NNOCHECK + tests completed but not checked
61 *
62 * NPASSED (global input/output) INTEGER
63 * NPASSED = NPASSED + tests which passed all checks
64 *
65 * INFO (global output) INTEGER
66 * 0 = test request ran
67 * -1 = end of file
68 * -2 = incorrect .dat file
69 *
70 * .. Parameters ..
