Hello! We propose util implementation into utils directory. You can see more about it there: https://github.com/StepanGulyaev/AFLGenParallel. We think it would be convenient to add to AFL util itself and some default configs for use. For example we can have configs based on that: https://aflplus.plus/docs/fuzzing_in_depth/#c-using-multiple-cores. Thank you for reading, we hope it helps.
