Hello I have just installed Octave 3.0.5 mingw32.
In installing process, the cpu of my computer was detected as core2duo(SSE3). However the cpu of my computer is the Ht-pentuim4 (prescott). I did not change the selection because the SSE3 is supported for my cpu. I would like to the supplemental explanation for the cpu selection in the OctaveForWindowsWiki. ******** If your cpu is detected as core2duo while the cpu of the computer is not the core2duo but the cpu supports SSE3, you can select 'Core2Duo (SSE#)' ******** Is the above explanation acceptable? BTW, the Altas library bundled with octave 3.0.5 mingw (Benjamin)is very fine in the following, # test n=2000; A=randn(n); B=randn(n);tic; C=A*B; t=toc, MFLOPS=2*n^3/t*1e-6 Octave-3.0.2 (mingw by Benjamin) t = 15.063 MFLOPS = 1062.2 octave-3.0.5 (mingw by Benjamin) t = 4.2344 MFLOPS = 3778.6 Octave-3.0.5 (mingw atlas optimized for my cpu) t = 3.5313 MFLOPS = 4531.0 The speed of atlas is much faster than that of the previous release and is only 20% slower than that of the optimized ATLAS!!!. I guess that you are using single threaded Atlas because : mkoctfile -p LIBS -lreadline -lncurses -lhdf5 -lz -lm -lws2_32 -lkernel32 I could not find -lpthread. This question comes from only curiosity so that I have no opinion for that. Anyway I again would like to express my appreciation for your great work!
