V Tune not showing P-core untilisation on Microarchitecture Exploration

[oliver_h]

For some reason the P-Core data is not showing on my 12900k on the matrix example.

I'm using V-Tune straight "out of the box" just running the example program as shown. However, in Threading it does show that all 16 (physical) cores are being being targeted as well as saying that on the console when using the example.

I have used V-Tune on my laptop which is also alderlake and cannot replicate the error.

Could there be a security feature stopping the drivers from being able to see the cpu event counters soemwhere?

Do you need something more?

Hi @Dom324 ,

Good day to you.

Can you please keep the screenshot of the HyperV status?

Thanks,

Hi,

Sorry for the delay.

Can you all please try to run the same analysis with the latest version of VTune Profiler (2023)?

We were able to see p-core metrics.

Thanks,

Hi All,

The above issue is resolved in the latest version of Vtune.

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue. Thank you!

Thanks,

Hi Jaideep,

  Issue seems to be fixed. I confirmed I still saw the issue on 2022.4.0 build 624343. 

I downloaded 2023.0.0 build 624757 and installed it. It seems to work.

I now see P core events. I can accept the solution. I intend to use Vtune some more for my work and glad to see it able to record those events.

Thanks,
