Where can I find a list of numpy functions which release the GIL?
gil, numpy, python
Solution
It's not guaranteed to catch everything, but I just ran:
git grep nogil
in my clone of the numpy repository. It turns up 82 usages in 2 files:
- `random/mtrand/mtrand.pyx`
- `random/mtrand/numpy.pxd`
Problem
I have found several SO questions asking about this in one way or another, but none of them actually either give a list or refer to one. This question refers to a wiki page, but while the wiki page talks about the GIL and multi-threading, it doesn't give a list of GIL releasing functions. This mailing list post indicates that the only way to find out is to read the numpy source. Really?
