- only tested on Debian Linux with a 16-thread amd64 CPU
- Windows may need DLLs to be shipped with the EXE
- using `-fopenmp` should be made optional via qmake somehow
(without the flag, parallelization pragmas are ignored
and it reverts to serial operation)
- assumes `status::update()` among other code is thread-safe,
it seems to work on my machine without issues...
