%description
The ATLAS (Automatically Tuned Linear Algebra Software) project is an
ongoing research effort focusing on applying empirical techniques in
order to provide portable performance. At present, it provides C and
Fortran77 interfaces to a portably efficient BLAS implementation, as
well as a few routines from LAPACK.

Projekt ATLAS (Automatically Tuned Linear Algebra Software -
automatycznie dostrajane oprogramowanie do algebry liniowej) to próby
badawcze skupiające się na stosowaniu technik empirycznych w celu
zapewnienia przenośnej wydajności. Aktualnie dostarczane są interfejsy
w C i Fortranie 77 do przenośnej, wydajnej implementacji BLAS, a także
kilku procedur LAPACK.
