This package contains the ATLAS (Automatically Tuned Linear Algebra
Software) libraries compiled with optimizations for the 3DNow extension to
the ix86 architecture. Red Hat Enterprise Linux also produces ATLAS build
with SSE, SSE2 and SSE3 extensions.
Notes on the Red Hat Enterprise Linux version of ATLAS

Because ATLAS relies on compile-time optimizations to obtain improved
performance over BLAS and LAPACK, the resulting binaries are closely
tied to the hardware on which they are compiled, and can likely result
in very poor performance on other hardware.
