cannot generate GPU roofline

[hxc]

I installed the advisor from oneAPI package, version:

    Intel(R) Advisor 2021.2 (build 609067)

    OS: Ubuntu 18.04

    GPU: Intel UHD Graphics 630

I also installed the OpenCL and Level 0 runtime from the github release:

dpkg -l | grep zero
    ii intel-level-zero-gpu 1.1.19792 amd64 Intel(R) Graphics Compute Runtime
    ii level-zero 1.2.4 amd64 oneAPI Level Zero
    ii level-zero-devel 1.2.4 amd64 oneAPI Level Zero

dpkg -l | grep opencl
    ii intel-igc-opencl 1.0.7181 amd64 Intel(R) Graphics Compiler for OpenCL(TM)
    ii intel-opencl 21.19.19792 amd64 Intel(R) Graphics Compute Runtime
    ii ocl-icd-libopencl1:amd64 2.2.11-1ubuntu1 amd64 Generic OpenCL ICD Loader
    ii ocl-icd-opencl-dev:amd64 2.2.11-1ubuntu1 amd64 OpenCL development files
    ii opencl-c-headers 2.2~2018.02.21-gb5c3680-1 all OpenCL (Open Computing Language) C header files

I tested sample code on both OpenCL runtime and Level 0 runtime.

The OpenCL sample is matrix multiply from: https://software.intel.com/content/www/us/en/develop/articles/sgemm-ocl-opt.html

The Level 0 sample is the official peak performance test:

https://github.com/oneapi-src/level-zero-tests/tree/master/perf_tests/ze_peak

The program ran correctly. I launched the advixe-gui, created a new project, and ran the "GPU Roofline Insights" analysis. However, after running the program twice, it shows "No floating-point operations detected" on GPU roofline pane. It is weird that the GFlops of a kernel is reported:

Can anyone help me?

Hi,

Thanks for reaching out to us.

We are trying to reproduce the issue.

Could you please share the result directory and the logs with us.

Also share the command to run the analysis from the advisor gui.

Please find the attached image which shows the option to generate command line.

Thanks.

Hello,

The command to run the level-0 perf test is:

/opt/intel/oneapi/advisor/2021.2.0/bin64/advisor -collect survey -profile-gpu -project-dir /home/hxc/intel/advixe/projects/perf-ze --app-working-dir=/home/hxc/level-zero-tests/out/perf_tests -- /home/hxc/level-zero-tests/out/perf_tests/ze_peak -t sp_compute
/opt/intel/oneapi/advisor/2021.2.0/bin64/advisor -collect tripcounts -no-trip-counts -flop -profile-gpu -project-dir /home/hxc/intel/advixe/projects/perf-ze --app-working-dir=/home/hxc/level-zero-tests/out/perf_tests -- /home/hxc/level-zero-tests/out/perf_tests/ze_peak -t sp_compute

And the result directory is attached.

Thanks

Did you perform steps from prerequisites page: https://software.intel.com/content/www/us/en/develop/documentation/advisor-user-guide/top/launch/set-up-environment-to-analyze-gpu-kernels.html
Looks like you have insufficient permissions to collect HW metrics..
