Automatically Tuned Linear Algebra Software

Official package sites : ·

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) for both c and F77 interfaces. It can also build a subset of the linear algebra routine LAPACK library or the full LAPACK using the reference LAPACK from Netlib.

USE flags
doc fortran generic lapack static-libs threads


Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
Add support for fortran
Build atlas assuming a fairly generic architecture (sse2 for x86, core2 for amd64)
Add support for the virtual/lapack numerical library
Build static versions of dynamic libraries as well
Add threads support for various packages. Usually pthreads
