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), and a subset of the linear algebra routines in the
LAPACK library.
.
The libraries in this package are built without any processor extension
instructions, and should run on all processors of this general
architecture, albeit less than optimally.
.
If you want to create an ATLAS packaged optimized for your processor, see the
section: "Building Optimized Atlas Packages on your ARCH" in README.Debian
