I’m currently profiling an OptiX 7.0 application using Nsight Compute 2019.5. The application runs on a GeForce RTX 2080 Ti board.
I encounter a whole load of stalls. According to the “details” page, section “warp state statistics”, roughly a third of the “warp cycles per issued instruction” is caused by stalls of type “misc” on average. Unfortunately, the description of such stalls is rather vague ("[…] warp […] being stalled on a miscellaneous hardware reason."). Is there a more detailed listing of reasons for encountering such stalls similar to ?  lists reasons for stalls of type “other” (which I think is equivalent to “misc”) for compute capabilities up to 6.*, but above board implements compute capability 7.5.
Thanks for your help!
