Similarly, you suggest using Cython's prange to parallelize computations. I haven't seen OpenMP used anywhere in NumPy or SciPy, and have the feeling that parallel implementations are left out on purpose. Am I right, or would parallelizing were possible be OK?

OpenMP is tricky under MacOSX: 10.7-10.9 had no support at all (they use clang <3.6). Since 10.10, the support is incomplete, well at least many code I tested fail with OpenMP (they run under linux and windows), I noticed wrong results, not only failure to compile ! Of course on can install gcc or icc, but this is not in Python's philosophy -- Jérôme Kieffer <google@terre-adelie.org>
