PROGRAM TCSPBL C C ================================================================== C ================================================================== C ==== TCSPBL -- CERTIFY COMPLEX SPARSE BLAS ==== C ================================================================== C ================================================================== C C TCSPBL IS THE CERTIFICATION PROGRAM FOR THE COMPLEX PRECISION C SPARSE BLAS. THE APPROACH USED TO CERTIFY THE SPARSE BLAS C IS AS FOLLOWS: C C 1. READ IN USER SPECIFIED INPUT ON OUTPUT UNIT, THRESHOLD VALUE C FOR TEST RATIO, AND THE SPECIFICATIONS FOR NZ, AND A. C 2. VERIFY THE CORRECTNESS OF THE USER SPECIFIED INPUT AND C ECHO TO THE OUTPUT UNIT. C 3. FOR EACH SUBPROGRAM IN THE COMPLEX PRECISION SPARSE BLAS C PERFORM ALL THE USER SPECIFIED TESTS AND PRINT A PASS/FAIL C MESSAGE. TESTS WHICH FAIL GENERATE ADDITIONAL OUTPUT. C C SPARSE BLAS SUBPROGRAMS WHICH ARE CERTIFIED BY THIS PROGRAM ARE C C CAXPYI CDOTUI CGTHRZ C CDOTCI CGTHR CSCTR C C THIS PROGRAM REQUIRES AN INPUT FILE ASSIGNED TO UNIT NIN C (CURRENTLY SET TO 5 BY A PARAMETER STATEMENT). THE DATA ON C THIS INPUT FILE CONTROLS THE OUTPUT UNIT, THE THRESHOLD VALUE C FOR THE NUMERICAL TESTING, AND THE SPECIFICATIONS FOR THE C TEST VALUES FOR THE LENGTH OF THE SPARSE VECTORS AND THE SCALARS C USED BY THE VARIOUS SUBPROGRAMS. AN EXAMPLE OF THE INPUT FILE C FOLLOWS C C LINE 1 'CBLATS.SUMM' NAME OF OUTPUT FILE C LINE 2 6 UNIT NUMBER OF OUTPUT FILE C LINE 3 100 MAX. NO. OF PRINTED ERROR MESSAGES C LINE 4 5.0 THRESHOLD VALUE OF TEST RATIO C LINE 5 6 NUMBER OF VALUES OF NZ C LINE 6 -1 0 1 2 5 9 VALUES OF NZ C LINE 7 3 NUMBER OF VALUES OF A FOR -AXPYI C LINE 8 (0.0,0.0) (1.0,0.0) (0.7,0.3) C VALUES OF A C C C THIS INPUT FILE IS READ USING FORTRAN-77 STANDARD LIST DIRECTED C INPUT. SINGLE QUOTES ARE REQUIRED AROUND THE NAME OF THE OUTPUT C FILE ON LINE 1. THE NUMBERS ON LINES 6 AND 8 CAN BE C DELIMITED BY BLANKS OR COMMAS. C C THIS PROGRAM WAS WRITTEN BY ROGER G.
