Improve FairGBM multi-threading

Open AndreFCruz opened this issue 3 years ago • 0 comments

According to our perf and valgrind benchmarks, a large percentage of CPU time is spent on synchronization of separate threads during training.

The net outcome of multi-threading is still positive, however when using OMP_NUM_THREADS=4 our code will only consistently use 2 threads, seeming unable to fully parallelize.
