yes, ATLAS:

It is an optimized BLAS/LAPACK library, useful for numerical
computation. The optimization is based on running many different tests
during the build, and the performances are CPU dependant (depends on the
L1/L2/L3 cache size, etc...). This means it is not possible to build it
as an rpm, but a src.rpm is still useful (since the user only has to run
rpmbuild bla bla).

Even if the software is able to optimize itself better by compiling
it on the target processor you could still build a generic version
for the architecture. Those who need the last bit of performance can
still rebuild the source then.

Also, I don't know if that software offers a library. If it does you
may need the generic version for linking other applications.
