Wow, I have now LU a little bit faster on the latest julia Fedora package than on my locally compiled julia:
julia> versioninfo() Julia Version 0.3.0 Platform Info: System: Linux (x86_64-redhat-linux) CPU: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz WORD_SIZE: 64 BLAS: libopenblas (DYNAMIC_ARCH NO_AFFINITY Haswell) LAPACK: libopenblasp.so.0 LIBM: libopenlibm LLVM: libLLVM-3.3 julia> include("code/julia/bench.jl") LU decomposition, elapsed time: 0.07222901 seconds, was 0.123 seconds with my julia FFT , elapsed time: 0.248571629 seconds Thanks for making and improving the Fedora package
