As a wild guess, I might say he saw multi-CPU numbers that either got reported as single-CPU, or someone just assumed they were single-CPU numbers. However, I haven't actually seen the numbers Bob saw - there is some chance that what he reported is accurate. >Itanium2, but I can’t come even close.

From what I understand, profiling is quite important for Itanium to get good results. This is why even the base SPEC scores were achieved with profiling runs, AFAIK. >The results are more or less in line with the SPEC CPU2000int results for Crafty >(see www.spec.org), some of which are (run times in seconds): > >Hewlett-Packard Company hp server rx2600 (1000 MHz, Itanium 2) >186.crafty 128 > >Advanced Micro Devices Epox 8KHA+ Motherboard, AMD Athlon (TM) XP 1900+ (CPU >MHz: 1600) >186.crafty 106 > >Intel Corporation Intel D850EMVR motherboard (3.06 GHz, Pentium 4 processor with >HT Technology) >186.crafty 86 > >Advanced Micro Devices ASUS A7N8X (REV 1.02) Motherboard, AMD Athlon (TM) XP >2800+ (CPU MHz: 2250) >186.crafty 76.3
