I don’t understand the code, but it’s good to see you doing things.

It means that I made changes to code, so that it can work with any multi-threading strategy. G’MIC is a interpretative language with JIT support, and you don’t have any control over automated multi-threading strategy. It can be thread 0 to thread N linearly, or even interleaved. So, the workaround is to make a image of size equal to cpus count, and do the multithreading there.

Yeah, I love image processing, I worked on it for 8+ years now.

As always, I do image processing. I’m a G’MIC filter developer. Recently, did some code changes to my combinatorics tools to be insensitive to multi-threaded strategy.
