PROGRAM SBLAT3** Test program for the REAL 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:* 'SBLAT3.SUMM' NAME OF SUMMARY OUTPUT FILE* 6 UNIT NUMBER OF SUMMARY FILE* 'SBLAT3.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* SGEMM T PUT F FOR NO TEST.
