5.7. atlas

Updated atlas packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The ATLAS (Automatically Tuned Linear Algebra Software) project is a research effort focusing on applying empirical techniques providing portable performance. The atlas packages provide C and Fortran77 interfaces to a portably efficient BLAS (Basic Linear Algebra Subprograms) implementation and routines from LAPACK (Linear Algebra PACKKage).

Bug Fix

Previously, binary files from the base atlas package contained illegal instructions from an incompatible instruction set (3DNow!). As a consequence, an "Illegal instruction" error was displayed. This update disables usage of the instruction set.
All users of atlas are advised to upgrade to these updated packages, which fix this bug.
