amplxe error while using Vtune on a multiThreaded application

[Ayman_Supcom]

Hello I am trying to use Vtune to profile my application withe the command:

[amplxe-cl -collect hotspots -result-dir vtune_outputs/formula_100  application.exe]

and i faced  the errors : 

amplxe: Error: Assertion failed: tpss_completion:126: (queue_buffer_data != 0) : . Please contact the technical support.
amplxe: Error: Assertion failed: tpss_stack_data_type:131: (stack->data) : . Please contact the technical support. 

Note that i am applying multi-threading using threading building blocks Library and thanks to some Logs I found out that the fail is happening when the program is executing the multi threaded function.

Also I am not facing the error when I am not trying to lunch Vtune.

Thank You.

Hi,

Thank you for posting in Intel Communities.

Can you please share the requested details below:

1. What is the version of Intel® Vtune?

2. Please share your OS (Windows 10,11 or Linux distribution) and processor details?

3. Please share the exact steps that you followed and a sample reproducer(sample application that is similar to the application you are trying to analyze)?

We tried threading building blocks library using the OneAPI sample(tbb-async-sycl sample code which was implemented using C++ and SYCL language for CPU and GPU) and it is running without any issues. Attaching the screenshot for reference.

Thanks,

Hi @JaideepK_Intel  Thank you for your response .

I am using  CentOS Linux version 7, my machine is Intel(R) Xeon(R) Gold 6256 CPU @ 3.60GHz and VTune version 2018, I built the application in debug mode . I tried to reproduce the error while using VTune and I had the attached error ,that doesn't occur while trying only to launch the application without VTune. I added an environment variable also To specify whether the execution of threads is sequential or parallel , and I noticed that the problem occurs only when I am using parallelization .

 can you please give me any suggestion about any possible common mistake i could have done , or any modification on the command so that i can avoid the error .

Thank You .

Ayman.

Hi,

As you mentioned, you are using Vtune 2018, can you use the updated version(Vtune 2022). Please note that CentOS 7 is not supported in the latest Vtune 2022 version. Please consider changing the OS and try with the latest Vtune version.

Work around: Try using docker (docker pull intel/oneapi-basekit) and profile application with remote ssh.
