[VTUNE] Collection Fail for CPU Compute/Media hotspots

[Bram_S_]

When running vtune-self-test.sh

GPU software event-based analysis with runtime tracing
Example of analysis types: GPU Compute/Media Hotspots (source analysis mode)
Collection: Fail
vtune: Warning: To enable hardware event-based sampling, VTune Profiler has disabled the NMI watchdog timer. The watchdog timer will be re-enabled after collection completes.

The check observed a product failure on your system.
Review errors in the output above to fix a problem or contact Intel technical support.

The system is ready for the following analyses:
* Performance Snapshot
* Hotspots and Threading with user-mode sampling
* Hotspots with HW event-based sampling, HPC Performance Characterization, etc.
* Microarchitecture Exploration
* Memory Access
* Hotspots with HW event-based sampling and call stacks
* Threading with HW event-based sampling
* GPU HW event-based analysis with runtime tracing

The following analyses have failed on the system:
* GPU Compute/Media Hotspots (source analysis mode)

Full log is attached.

When I do a command-line collection for gpu-hotspots, I get some additional information.

This assertion failed:

Assertion failed: tool:1353: g_instr_global.is_libpthread_so_initialized == 0

I used this command-line:

$ vtune -collect gpu-hotspots -target-process=viewer -d=5
vtune: Warning: To enable hardware event-based sampling, VTune Profiler has disabled the NMI watchdog timer. The watchdog timer will be re-enabled after collection completes.
vtune: Error: Assertion failed: tool:1353: g_instr_global.is_libpthread_so_initialized == 0 : g_instr_global.is_libpthread_so_initialized == 1
. Please contact the technical support. 
vtune: Collection failed.
vtune: Internal Error

Thanks.

UPDATE

vtune-self-checker.sh succeeds on all analysis types if I add this to the command line:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libpthread.so.0

Hi,

Thank you for posting in intel communities.

Sorry for the confusion. As there is an active discussion in this thread (https://community.intel.com/t5/Analyzers/VTUNE-self-check-collection-fail-on-GPU-Computer-Media-Hotspots/m-p/1482337#M23379), we will discuss it in that thread and closing the remaining threads.

Thanks,

Jaideep
