Using VTune Profiler with Visual Studio 2019

shekhar__gaurav — Fri, 22 May 2020 06:57:53 GMT

Hi,

I have installed VTune Profiler recently to profile an OpenCL project on VS2019. I need some help with how can I profile my code with VTune.

I could not find anything helpful yet. If I can get some document that discusses the step-by-step procedure starting from the welcome page, it would be very helpful for a newbie like me.

Thanks,

Gaurav.

Hi,

I followed this document for profiling my OpenCL application, but I am unfortunately getting the error as attached.

I selected my output .exe in Application
And the relevant parameters in Application Parameters
In the analysis type, I selected GPU Offload

I see the following error after I click Start.

Hi,

That is working fine. I tried with the sample example that packaged with VTune. I got the following outputs.

Hi,

Thanks for the immediate response.

Seems like your CPU based analysis is working fine.Did you try that code sample for GPU offload?

If not, try that and send the screenshot.

Hi,

I tried that just now and found the same error as my application.

Hi,

Thanks for the update.

This happens when application invokes other processes for which the user does not have read privileges ,so before running GPU offload uncheck the "Analyze child processes" option in the what pane in Vtune GUI.

Let us know if the issue persists.

Is there something else that's causing the issue?

Hi,

Try running self checker script in vtune installed directory.Self checker script is to validate whether the appropriate drivers are installed and system is set up properly to collect performance data.You can find vtune-self-checker.sh script in <install-dir>/bin64. After running self checker script you will get a log file.

Also try in a standalone version and check whether you get the same error.

Hi,

I could not find vtune-self-checker.sh on my system. Is something wrong with my installation?

On running in the standalone version, my .exe gave a crash message and I got the error as in the attached snap.

Hi,

We have 2021.1-beta06 and we have self checker script in it.May I know your vtune version?

Hi,

The latest I could find on the website is 2020 update 1, as shown in the image attached.

I am not sure where to find the version you have.

Hi,

Try installing the latest version of oneapi basekit for windows(https://dynamicinstaller.intel.com/oneapi/toolkits/base-kit/win/).After installing you will find vtune-self-checker.bat in the path intel/inteloneapi/vtune/bin64 .Run that file and let us know the update.

Hi,

Following are my findings after installing oneapi:

matrix.exe crashes after running vtune-self-checker.bat
It gives some errors at each step. Snaps attached.
