sci@gentoo.org Gentoo Science Project ATLAS is an approach for the automatic generation and optimization of numerical software. Currently ATLAS supplies optimized versions for the complete set of linear algebra kernels known as the Basic Linear Algebra Subroutines (BLAS) for both c and F77 interfaces. It can also build a subset of the linear algebra routine LAPACK library or the full LAPACK using the reference LAPACK from Netlib. Build atlas assuming a fairly generic architecture (sse2 for x86, core2 for amd64) math-atlas
