Hi, Sorry; my first message wasn't under 40 KB with the attachments, so here's the same message but with the log files at http://www.stat.washington.edu/~hoytak/logs.tar.bz2. Which ones ? Sorry; ATLAS = 3.9.4 and lapack=3.2. I'll give 3.8.2 a shot per your advice. You should not do that,

Hi, I honestly don't think those flags matter much in the case of numpy/scipy. In particular, using SSE and co automatically is simply impossible in numpy case, since the C code is very generic (non-aligned - non contiguous items) and the compiler has no way to know at compile time which
