PROGRAM DBLAT3
*
*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> Test
program for the
DOUBLE PRECISION Level 3 Blas.
*>
*> The
program must be driven by a short
data file. The first 14 records
*> of the
file are
read using list-directed input, the last 6 records
*> are
read using the
format ( A6, L2 ). An annotated example of a
data
*>
file can be obtained by deleting the first 3 characters from the
*> following 20 lines:
*>
'dblat3.out' NAME OF SUMMARY OUTPUT
FILE
*> 6
UNIT NUMBER OF SUMMARY
FILE
*>
'DBLAT3.SNAP' NAME OF SNAPSHOT OUTPUT
FILE
*> -1
UNIT NUMBER OF SNAPSHOT
FILE (NOT USED
IF .LT. 0)
*> F
LOGICAL FLAG, T
TO REWIND SNAPSHOT
FILE AFTER EACH RECORD.
*> F
LOGICAL FLAG, T
TO STOP ON FAILURES.
*> T
LOGICAL FLAG, T
TO TEST ERROR EXITS.
*> 16.0 THRESHOLD VALUE OF TEST RATIO
*> 6
NUMBER OF VALUES OF N
*> 0 1 2 3 5 9 VALUES OF N
*> 3
NUMBER OF VALUES OF ALPHA
*> 0.0 1.0 0.7 VALUES OF ALPHA
*> 3
NUMBER OF VALUES OF BETA
*> 0.0 1.0 1.3 VALUES OF BETA
*> DGEMM T PUT F FOR NO TEST. SAME COLUMNS.
*> DSYMM T PUT F FOR NO TEST. SAME COLUMNS.
*> DTRMM T PUT F FOR NO TEST. SAME COLUMNS.
*> DTRSM T PUT F FOR NO TEST. SAME COLUMNS.
*> DSYRK T PUT F FOR NO TEST. SAME COLUMNS.
*> DSYR2K T PUT F FOR NO TEST. SAME COLUMNS.

*> 10-9-00: Change
STATUS=
'NEW' to 'UNKNOWN' so that the testers
*> can be run multiple times without deleting generated
*> output files (susan)
