Sun Performance Library documentation:

Sun Performance Library Reference
The Sun Performance Library is a library of subroutines and functions to perform useful operations in computational linear algebra and Fourier transforms. It is based on the standard libraries BLAS1, BLAS2, BLAS3, LINPACK, LAPACK, FFTPACK, and VFFTPACK. Each subprogram in the Sun Performance Library performs the same operation and has the same interface as the standard version, but is generally much faster and sometimes more accurate.
