Yeah, but that's C++. It won't work in Python without this directive:
from __future__ import braces

Hi,
Can somebody explain to me how would you proceed in releasing the GIL and
whether you think it will have consequences?
Thanks

You release the GIL in C-level code when you don't need to work with
Python objects for a while. Simple exa

I use openMp in a C-extension that has an interface with Python.
In its simplest form I do this:
== code ==
#pragma omp parallel
{
#pragma omp for
for(int i=0; i<10; i++)
{
// multiply some matrices in C
