Netlib is your friend (add to Favorites):

Basic stuff: BLAS (Basic Linear Algebra Subprograms) -- www.netlib.org/blas/

Advanced stuff: LAPACK (Linear Algebra Package) -- www.netlib.org/lapack/

BLAS and LAPACK are also contained in CXML library you can find in your CVF distribution. If you need maximal performance, pay attention to this passage on Lapack page:

Highly efficient machine-specific implementations of the BLAS are available for many modern high-performance computers. For details of known vendor- or ISV-provided BLAS, consult the BLAS FAQ. Alternatively, the user can download ATLAS to automatically generate an optimized BLAS library for the architecture. A Fortran77 reference implementation of the BLAS in available from netlib; however, its use is discouraged as it will not perform as well as a specially tuned implementation.

Hope this helps,
