I’m running Nsight Graphics 2020.5 on Linux using OpenGL, and see this reported on:
Range Profiler / SM Section / SM Occupance: 10.06
When I consult the User Guide:
…the SM Occupancy value gives you a percentage of how full the shader unit was with warps.
I’m pretty sure that this is not a percentage, though. The mouse-over tool tip refers to the metric:
This is not a percentage. If it was, it would be annotated with .pct or .pct_of_peak_xxx
My profile run was on GTX 1650, which reports a warp size of 32, I assume it is only occupied at a third of capacity?
