These particular results have to do with solving dense systems of linear equations using the LINPACK FORTRAN software of order 100 (notably the SGEFA and SGESL column-oriented algorithms, based upon the BLAS series of subprograms). This is an application-specific set of benchmarks resulting in many cases MFLOP ratings well below the theoretical performance of each machine (i.e., the machines might well perform differently with somewhat different problems, even similar floating-point-intensive problems). ``Rolled BLAS'' means BLAS routines not unrolled for optimal performance. [of the machines listed below, I'd be tempted to call the FPS-264 and Alliant FX-1 "personal supercomputers" in terms of their size, power requirements, etc.] Computer OS/Compiler MFLOPs -------- ----------- ------ CRAY X-MP/4 not tested CRAY X-MP/2 CFT 1.13 (rolled BLAS) 24 CRAY-2 (1 processor) CFT 2.70 (rolled BLAS) 15 CRAY-1S CFT (rolled BLAS) 12 Alliant FX/8 (8 CEs) FX FORTRAN v2.0.19 (rolled BLAS) 7.6 SCS-40 CFT 1.13 (rolled BLAS) 7.3 FPS-264 F02 APFTN64 OPT=4(rolled BLAS) 5.6 Convex C-1 FORTRAN 1.6 (rolled BLAS) 2.9 IBM 3081K (1 processor) H enhanced opt=3 2.1 Alliant FX/1 (1 CE) FX FORTRAN v2.0.19(rolled BLAS) 1.6 DEC VAX8800 VMS V4.3 .99 DEC VAX8650 VMS V4.1 .70 DEC VAX8500 VMS V4 .65 DEC VAX8600 VMS v4.1, FORTRAN 4.2 .49 Harris HCX-7 w/fpp f77 1.0 .48 Sun-3/160M+FPA f77 -O -ffpa 3.1 .40 Harris H800 SAUF77 .23 IBM 370/158 H opt=3 .23 Celerity C1200 4.2Bsd Unix f77 .21 DEC VAX11/785 FPA VMS V4.1 .20 DEC VAX8200 VMS V4.3 .15 DEC VAX11/780 FPA VMS V4.1 .14 DEC microVAX II VMS V4.1 .13 DEC VAX11/750 FPA VMS V4.1 .12 Sun-3/75 w/68881 f77 -O -f68881 3.0 .079 Apollo DN460/660 AEGIS 8.0 FTN .069 HP 9000 Series 320 HP-UX f77 5.15 .063 Apollo DN3000 AEGIS 8.0 FTN .062 Masscomp MC500 FPP 3.1 FORTRAN .061 IBM RT PC Model 20 f77 .036 Apollo DN320 AEGIS 8.0 FTN .028 Apollo DN550 FPA AEGIS 8.0 FTN .025 IBM AT 80287 PROFORT 1.0 .012 IBM PC 8087 PROFORT 1.0 .012 IBM AT 80287 Microsoft FORTRAN 3.2 .0091 Apple Macintosh ABSOFT 2.0b .0038 -- Bob Cunningham bob@hig.hawaii.edu
