The details are at: http://www.specbench.org/osg/cpu2000/results/res2002q3/cpu2000-20020715-01485.html A quick summary goes like this: SPECfp_base2000 = 1356 CPU: 1000MHz Itanium 2 machine: zx6000 workstation OS: Debian 3.0 Linux with 2.4.18 kernel compiler: Intel C++ and Fortran Compiler 6.0.1 for Linux To be fair, I need to mention that hp-ux currently gets higher SPECint numbers on Itanium 2 (and, no, there are no ia64 linux SPECint numbers at specbench.org; don't ask me why---I simply don't know as I'm not directly involved with SPECmarking...). The reason for this is that the nature of the SPECint benchmarks causes Linux to pay the full cost of the LP64 data model without reaping any of the benefits (hopefully, this is an issue that will be addressed by SPECcpu2004). Also, Linux could benefit from superpage support to reduce TLB-pressure on some of the benchmarks and compiler improvements would always help as well, of course. Enjoy, --david
