GPU Compute Hotspots (Source Analysis) - hardware support?

Hey everyone,

I'm trying to optimize an OpenCL program to run faster on Intel graphics. The only Intel device I have is my laptop with an i5-8350U however, and I'm struggling with profiling kernels.

 

GPU Compute/Media Hotspots in Characterization mode gives somewhat limited information (it does tell me basic information about the kernel, but no disassembly or line-by-line profiling. Only general GPU stats.)

 

The GPU Offload analyzer does give me the source code and disassembly, including a mapping between them. But no runtime information or whatever, which would probably also be helpful.

 

Finally, the GPU Hotspots - Source Analysis mode tells me "GPU software profiling does not support current hardware". Is this a limitation of the current version (VTune 2024.0) and could I get it working by using an older version of VTune, or is this mode just not available whatsoever on my hardware?

Hi,

 

Thank you for posting in Intel communities.

 

To understand your issue better could you please share the below information?

  • Attach valid screenshots for our reference.
  • Please share the kernel and also OS details (exact distros example: ubuntu, centos, RHEL)
  • Please run the below command and attach the log file as well.

                sh <oneapi_install_directory>/vtune/latest/bin64/vtune-self-checker.sh

                (eg: sh /opt/intel/oneapi/vtune/latest/bin64/vtune-self-checker.sh)

 

Thanks,

Jaideep

Gen 9 integrated GPU is no longer supported by latest VTune Profiler, maybe you can try with 2023.2 or old release.
