Does VTune support the "Lunar Lake" GPU profiling? - Intel Core Ultra 7 268V

[JIANHUI_D_Intel]

Hi Support team:

  I used the VTune (Windows) for "Lunar Lake" GPU profiling, but it does not provide any data about GPU. It's good for MTL GPU Profiling.

 Both latest VTune are tried:

• Intel_VTune_Profiler_2024.2.0_nda.zip
• Intel_VTune_Profiler_2024.1.0_internal.zip

Does VTune support the "Lunar Lake" GPU profiling? - Intel Core Ultra 7 268V

If not, Any support plan?

[yuzhang3_intel]

Please provide the OS version, thanks.

[JIANHUI_D_Intel]

Windows Version Microsoft Windows 11 Enterprise Edition (x64), Version 23H2, Build 22631.3737
DirectX Version 12.0

Please try with the coming 2024.2.1 release, the current VTune release doesn't support LNL for GPU profiling.

[JIANHUI_D_Intel]

Thanks.

Hopefully it releases soon.

[JIANHUI_D_Intel]

May I ask the estimated timeline of 2024.2.1 release?

I'm really looking forward to it!

[yuzhang3_intel]

I don't know the accurate delivery date, but it should be released in two weeks. Actually, the pre-build is ready. It's just in the delivery process.

[yuzhang3_intel]

VTune 2024.2.1 has been released, you can try it. 

[JIANHUI_D_Intel]

Thanks for letting me know. I'll try out the new release.

[JIANHUI_D_Intel]

Confirmed  VTune 2024.2.1 captures GPU metrics on LNL. Thank you the supporting.

[JIANHUI_D_Intel]

But unlike the MTL results, the `Packet Type` Grouping is empty, is it expected?

[yuzhang3_intel]

Did you run which analysis type?

[JIANHUI_D_Intel]

It's GPU Compute/Media Hotstpots (preview).

Attached the MTL vs LNL screenshot for this issue.

[yuzhang3_intel]

Did you profile system using GPU hotspots analysis type? and if the workloads are the same when profiling on MTL and LNL?

[JIANHUI_D_Intel]

Yes. It's system profiling not launch application, for both MTL/LNL.

[yuzhang3_intel]

Not sure if this is one issue, let me check and then give you an update. Thanks.

[JIANHUI_D_Intel]

This feature is quite helpful in GPU computing profiling on previous MTL and so on.

For example, if we captured 10s vtune result, but we filter/zoom the 2s~5s and get the perf stat of this period of time.

Hopefully, this feature will be back soon for LNL.

[yuzhang3_intel]

Thanks for the clarification, I will escalate the issue to engineering team and feedback later.

[yuzhang3_intel]

In addition, can you share your VTune data here?

[JIANHUI_D_Intel]

Sure.

Do you mind to share your mail, that i can share by Teams? Or ping me jianhui.j.dai@intel.com 

[yuzhang3_intel]

Sure, I have shared one link with you for uploading your data.
