Just whatever you get by default with pip install numpy... Changing the benchmark to run with a 1024x1024x1024 matrix instead of a 128x128x128 does speed up numpy significantly though

    Naive:             6.275 GFLOPS            0.05x faster than Python
    Vectorized:       22.259 GFLOPS            0.19x faster than Python
    Parallelized:     50.258 GFLOPS            0.42x faster than Python
    Tiled:            59.692 GFLOPS            0.50x faster than Python
    Unrolled:         62.165 GFLOPS            0.52x faster than Python
    Accumulated:     565.240 GFLOPS            4.74x faster than Python
