I just got an Athlon64 X2 4200+ and the first thing I did when I got the machine stabilized was build "blas-atlas" and "lapack-atlas" (3.7.30). New versions of Atlas generally show up in Portage or the science overlay within a day after Clint releases them, so I don't usually test the upstream source. The best I got out of my machine was something like 7 GFLOPS on a 32-bit test with 3.7.30, and there were some cases that looked like they should have done better. So I definitely want to test this 160M setting. -- gentoo-science@gentoo.org mailing list
