Waring about continuous profiling mode

How do I resolve this error? I do not have another copy of vtune running. I am getting this attaching to a process and trying the micro architecture insights. I seem to be able to do the hotspot stuff OK.

Hi,


Thank you for posting in Intel Forum.

The possible reason for this error might be because PMU(Performance Monitoring Unit) are used by some other processes or VTune might have got killed in midway of execution.


Can you please provide us with details like VTune version and the OS type. Make sure that vtune-self-checker script is running fine to validate that appropriate drivers are installed and the system is set up properly to collect performance data.

On linux :

<install-dir>/bin64/vtune-self-checker.sh

On windows :

<install-dir>/bin64/vtune-self-checker.bat


If you are running on linux, check in ‘top’ if any process like vtune sep perf etc are running.If on windows , see task manager.

Also try restarting the machine and executing again.


Regards,

Raeesa

It says vtune 2020 update 2. build 610396. I run it on Windows 10 build 2004.

>VTune might have got killed in midway of execution.

Well I don't remember killing it with task manager or anything that vicious but I certainly terminate it by clicking on the red x a lot.

I can well imagine rebooting will resolve the issue. I really don't want to reboot as I actually use this machine for stuff. I could see a process called vtune backend running but killing that made no difference.
