Profile Vompute-only Vulkan application

Developer Tools Nsight Compute

Hi,

In ncu I can launch a System Trace activity to capture some Vulkan activity, which suggests that the tool knows about Vulkan. But I can’t launch a profile session - I always get ==WARNING== No kernels were profiled. I couldn’t find anything related to Vulkan in the user guide, but I still believe it should possible to collect the metrics - after all the GPU runs the same SASS no matter if it was launched with Vulkan or Cuda. Maybe there’s an API exist that can tell the device to start/stop the capture? Or Vulkan-Cuda interoperability path?

Hi, @nikitablack

Nsight Compute only support CUDA profile.

If you want to analysis Vulkan application, please use Nsight System or Nsight Graphics instead.

Hi @veraj

Thank you for the reply. I am aware of Nsight Systems, but unfortunately it does not provide the information I’d like to have, for example SASS.
