Nsight Systems profiling NVTX blocks are broken #501

Closed sbryngelson closed 2 months ago

sbryngelson commented 3 months ago

For NVIDIA GPU Nsight Systems profiling, the NVTX blocks were, at some point, broken. It is unclear why, though it seems like it should be easy to track down. An example is in the image below for a 3D case.

Out of curiosity, do you know when you most recently creating a working profile? I figured the fastest way I could address this is to determine which commit broke profiling.

I am not sure. I suspect it was either the PR that introduced AMD GPU support (I think @anandrdbz as primary author but it has like 20 contributors), or @wilfonba's PR that abstracted out all RHS functionality to different subroutines. I'm not sure which (or it could be something else).
