Atlas might have installed a liblapack, with the (few) functions that it overrides with faster ones. It's by no means a complete LAPACK installation. Have a look at the difference in library sizes; a full LAPACK is a few megs; Atlas's routines are a few hundred K.
OK, I'm really confused now. I got it working, but it seems to have virtually identical performance to the Numeric-supplied lapack-lite. I'm guessing that the LAPACK package I emerged does NOT use the atlas BLAS. if the atlas liblapack doesn't have all of lapack, how in the world are you supposed to use it? I have no idea how I would get the linker to get what it can from the atlas lapack, and the rest from another one. Has anyone done this on Gentoo? If not how about another linux distro, I don't have to use portage for this after all. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov
