| PackageDescription | Automatically Tuned Linear Algebra Software,3dnow shared
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.
.
These libraries use the 3dnow extensions only available on AMD
3dnow and later processors. Please note that the floating point
produced by these extensions is not IEEE compliant.
.
On some architectures, multiple binary packages are provided to take
advantage of certain commonly available processor instruction set
extensions. The instruction extension set used is indicated in the
package name, with 'base' denoting no extensions. In general, you
will obtain the best performance by installing the package with the
most advanced instruction extension set your machine is capable of
running. |
