Assertion failed in tpss_deepbind_notify_on_pthread_loaded

Dear Intel VTune Support Team,

I am learning to use vtune_profiler_2020.0.0.605129 on Arch Linux (kernel 5.3.13) and the CPU based analyses work on my machine.

But I have not managed to run per-program GPU analyses. (System wide GPU profiling seems to work)

E.g. when issuing the following command to profile the program glxspheres64

TPSS_DEBUG=1 /opt/intel/vtune_profiler_2020.0.0.605129/bin64/vtune -collect graphics-rendering -app-working-dir /usr/bin -- /usr/bin/env MESA_GLSL_CACHE_DISABLE=true /usr/bin/glxspheres64

I get the following output:

log4cplus:ERROR Unable to open file: ./tpss-2020.03.14-10h16m40s.405792.log
vtune: Warning: The option to analyze all processes running on the system is enabled for this analysis type by default.

... (output continues) ...

I get similar tpss_deepbind_notify_on_pthread_loaded assertions for other rendering applications.

I am using the Mesa graphics driver:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2) 

Do you have any advice how to resolve this issue?

I have attached the resulting analysis file for you.
The same error results without TPSS_DEBUG=1 and without MESA_GLSL_CACHE_DISABLE=true.

regards,
Christian

Hi nand571,

I already have the latest version for which I am referring to the misbehaving with glibc.

Best,
George
