Linux-2.4.17, redhat-7.2 based (modifications for diskless), NV7m, 2 PC2100 Dimms. Duron 950: (100 Mhz FSB, 100 Mhz memory, 66 Mhz agp) Function Rate (MB/s) RMS time Min time Max time Copy: 742.4336 0.0889 0.0862 0.0899 Scale: 443.9945 0.1495 0.1441 0.1507 Add: 958.3234 0.1030 0.1002 0.1037 Triad: 570.7626 0.1728 0.1682 0.1740 Athlon XP1600, 1.4 Ghz: (133 Mhz FSB, 133 Mhz memory, 66 Mhz agp) ------------------------------------------------------------- Function Rate (MB/s) RMS time Min time Max time Copy: 827.1189 0.0777 0.0774 0.0786 Scale: 726.8103 0.0887 0.0881 0.0901 Add: 994.5098 0.0977 0.0965 0.1059 Triad: 858.9759 0.1121 0.1118 0.1140 Apparently the XP's prefetch helps in some cases where nvidia's doesn't, i.e. scale and triad. Doesn't manage much higher peak bandwidth which is fairly impressive. In any case these are the best numbers I've seen from an Athlon based system. -- Bill Broadley Mathematics/Institute of Theoretical Dynamics UC Davis
