Sure? I have turmalin:/usr/local/src/ATLAS/>ls CONFIG/ARCHS/ 21164.tgz ConfDump.log Makefile PIIISSE1.tgz PPCG4AltiVec.tgz 21164GOTO.tgz CreateDef.sh P4SSE1.tgz POWER.tgz PPRO.tgz 21264.tgz CreateDirs.sh P4SSE2 POWER2Thin.tgz SGIIP28.tgz 21264GOTO.tgz CreateTar.sh P4SSE2.tgz POWER3.tgz SGIIP30.tgz ATHLON.tgz HP9735.tgz P5MMX.tgz PPC604.tgz SunUS2.tgz ATHLON3DNow2.tgz IA64Itan.tgz PII.tgz PPC604e.tgz SunUS5.tgz ATHLONSSE1.tgz KillDirs.sh PIII.tgz PPCG4.tgz negflt.c so it would seem that there's both P4SSE1 and PIIISSE1. However, "lannerfalk" (which you shared an office with for a while) is a P4, with SSE2, and actually quite difficult to tell apart from the Xeon chips in "turmalin": CPU: L1 I cache: 12K, L1 D cache: 8K CPU: L2 cache: 512K CPU: Hyper-Threading is disabled CPU: Common caps: 3febfbff 00000000 00000000 00000000 CPU0: Intel(R) Pentium(R) 4 CPU 2.20GHz stepping 04 vs. CPU: Trace cache: 12K uops, L1 D cache: 8K CPU: L2 cache: 512K CPU: Physical Processor ID: 0 Intel machine check reporting enabled on CPU#1. CPU: After generic, caps: bfebfbff 00000000 00000000 00000000 CPU: Common caps: bfebfbff 00000000 00000000 00000000 CPU1: Intel(R) Xeon(TM) CPU 2.80GHz stepping 07 And their /proc/cpuinfo entries are also similar except for the clock speed and number of siblings. So SSE2 is certainly not the difference between P4 and Xeon - stepping number issue, perhaps? -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
