As some of you may know, an optimized version of the BLAS library
for PentiumPro machines running Linux has been made available
recently. You can download it from


Obviously this can be used to speed up the LinearAlgebra module in
NumPy. Unfortunately the necessary compilation and linking steps are
not totally trivial, so for those who would rather not try, I have
prepared a binary release, i.e. the file lapack_lite.so statically
linked with the optimized BLAS (and in fact statically linked with
everything else, to avoid compatibility problems). You can get
it via my Web page at


Be warned that I haven't tested this a lot, but for my applications it
works fine and given a speedup of roughly 30% for large matrices.
