- The only prerequisite for NumPy is Python itself. If you don’t have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and other commonly used packages for scientific computing and data science.
- Jul 26, 2012 · There is a second, possibly surprising improvement, provided by set_openblas_num_threads(int). When I use “export OPENBLAS_NUM_THREADS=x”, implicit parallelization employs 4 threads, for all x >= 4, on my 4 dual-core system. However with set_openblas_num_threads, I can utilize all 8.
The Python implementations of matrixstatistics and matrix_multiply use NumPy v1.14.0 and OpenBLAS v0.2.20 functions; the rest are pure Python implementations. Raw benchmark numbers in CSV format are available here and the benchmark source code for each language can be found in the perf. files listed here .

Many Python numeric packages, including NumPy and SciPy, are optimized and come with MKL built-in. It is a free (no-cost) download. You can get the NumPy package from Anaconda, and then get Anaconda's "MKL Optimization" option (https://docs.continuum.io/mkl-optimizations/). It is also a free (no-cost) download.

- Installing Numpy with OpenBlas // under python numpy. I just went through the frustrating but in the end rewarding experience of trying to install numpy in my school computing RHEL5 environment where I don't have sudo privileges or much control over the environment. In the end, I learned quite a bit!
