Hi All- I've just finalized the process of removing OpenMP from our codebase. See https://lists.launchpad.net/kicad-developers/msg34520.html for some discussion as to why this was needed.
TLDR; MacOS doesn't have OpenMP. Rather than segment our codebase to use different kinds of thread pooling, I've standardized the threading into std::thread. This includes connectivity, zone filling and 3d-viewer. There are a few side benefits to those not on Mac as well. Notably, OpenMP was stalling during the ratsnest/connectivity routines as the different threads waited for the pool to clear. Moving to the std::threads speeds this up enormously. There was some concern about the overhead of multiple threads as opposed to a thread pool. While I don't see any problematic effects under Mac or Linux, I'd like to hear people's experiences on MSW and whether there are drawbacks/problems to this approach. Best- Seth
