Assert failed while running Profiler 2020 Update 2

[Mentopolis]

Hello,

while running our C++ application in Profiler 2020 update 2 we get in most runs a assertation. The program abort and no performance report is created. Without profiler no such error appears.

Assertion failed: thread_manager_impl:1332: (threads_count != (tpss_u32_t)(-1)) : . Please contact the technical support.

regards

Hi,

Thanks for posting in Intel forums.

Please let us know the platform details so that we can try from our side.Also run the self checker script which is located in <install_dir>/bin64 .This script is used to validate your installation and system setup,so run this script and let us know the result.

Hello,

Computer is a Intel (R) Core (TM) I7-2760QM CPU with 2.40 Ghz

when running the checker script in Admin mode i get a Blue-Screen with "SYSTEM_SERVICE_EXCEPTION" .. in common i can run in Admin mode but sometimes i also get a bluenscreen when set samples lower than 10 ms

when running the checker in normal user mode i get :

What analysis are you trying to run? Looks like SEP drivers are not installed. Please make sure the drivers are installed and then try H/W events based sampling collection.

[Mentopolis]

Just reinstall the software from scratch.. the same result as in the first comment. Are there custom steps needed for setup this driver ?

[Vinutha_SV]

Looking at the logs, it is clear that SEP driver is not installed and so h/w event based sampling is failing.

You can install SEP drivers on windows, please refer to below link:

Hi,

We are forwarding your case to Subject Matter Experts.

Thanks

[Vinutha_SV]

Can you please attach the logs and the result directory to work on the issue?

[Vinutha_SV]

Hi,

Since I have not heard from you since 2 weeks, I will be closing this thread in next 2 days.

[Mentopolis]

sorry for the delay the first mail was gone into the Spam folder.

It seems to work after this steps. Even the hardware based sampling does not show an Bluescreen.

thank you for your support

[Vinutha_SV]

Good to know that. I will be closing this thread.
