linear eigenvalue problems formulated in either standard or generalized form,
as well as other related problems such as the singular value decomposition.
The emphasis of the software is on methods and techniques appropriate for
problems in which the associated matrices are sparse, for example, those
arising after the discretization of partial differential equations.")

     "ATLAS is an automatically tuned linear algebra software library
providing C and Fortran77 interfaces to a portably efficient BLAS
implementation, as well as a few routines from LAPACK.

Optimization occurs at build time.  For this reason, the library is built on
the machine where it is installed, without resorting to pre-built substitutes.

Before building the library, CPU throttling should be disabled.  This can be
done in the BIOS, or, on GNU/Linux, with the following command:

@example
# cpupower --governor performance
@end example

Failure to do so will result in a library with poor performance.")
