pengzhao-intel commented on issue #9939: add multi proposal operator (cpu version) and fix the bug in proposal op (gpu version) URL: https://github.com/apache/incubator-mxnet/pull/9939#issuecomment-370225375 @wkcn Nice work for the parallelization by OMP. **2X** speedup is a good start point. I see you have added several OMP in the code. Could you help profile where is the performance bottleneck now? PS: you may need to add `gettimeofdate` in your C code and identify the most time-consuming loop (or section).
