SUBROUTINE PSGSEPREQ( NIN, MEM, MEMSIZE, NOUT, ISEED, NTESTS,
$ NSKIPPED, NNOCHECK, NPASSED, INFO )
*
* -- ScaLAPACK test routine (version 1.7) --
* University of Tennessee, Knoxville, Oak Ridge National Laboratory,
* and University of California, Berkeley.
* October 15, 1999
*
* .. Scalar Arguments ..
INTEGER INFO, MEMSIZE, NIN, NNOCHECK, NOUT, NPASSED,
$ NSKIPPED, NTESTS
* ..
* .. Array Arguments ..
INTEGER ISEED( 4 )
REAL MEM( MEMSIZE )
* ..
*
* Purpose
* =======
*
* PSGSEPREQ performs one request from the input file 'SEP.dat'
* A request is the cross product of the specifications in the
* input file. PSGSEPREQ prints one line per test.
*
* Arguments
* =========
*
* NIN (local input) INTEGER
* The unit number for the input file 'SEP.dat'
*
* MEM (local input) REAL ARRAY, dimension MEMSIZE
* Array encompassing the available single precision memory
*
* MEMSIZE (local input) INTEGER
* Size of MEM array
*
* NOUT (local input) INTEGER
* The unit number for output file.
* NOUT = 6, output to screen,
* NOUT = 0, output to stderr.
* NOUT = 13, output to file, divide thresh by 10
* NOUT = 14, output to file, divide thresh by 20
* Only used on node 0.
* NOUT = 13, 14 allow the threshold to be tighter for our
* internal testing which means that when a user reports
* a threshold error, it is more likely to be significant.
*
* ISEED (global input/output) INTEGER array, dimension 4
* Random number generator seed
*
* NTESTS (global input/output) INTEGER
* NTESTS = NTESTS + tests requested
*
* NSKIPPED (global input/output) INTEGER
* NSKIPPED = NSKIPPED + tests skipped
*
* NNOCHECK (global input/output) INTEGER
* NNOCHECK = NNOCHECK + tests completed but not checked
*
* NPASSED (global input/output) INTEGER
* NPASSED = NPASSED + tests which passed all checks
*
*
*
* INFO (global output) INTEGER
* 0 = test request ran
* -1 = end of file
* -2 = incorrect .dat file
*
*
* .. Parameters ..
