Hi,

When I trying to generate the roofline model using Advisor via Devcloud, I am presenting the following error:

Assertion failed: m_gpuBandIdx.exist()
file: vcs/tpssplug2/src/tripcounts/tripcounts_plugin_bridge.cpp:1249

Aborted

Command used: advisor --collect=roofline --profile-gpu –-project-dir=./ -- ./stencil_code input.dat

Hi ,


Thank you for posting in Intel Forum .

Could you please share :

  1. The application and steps to reproduce the issue
  2. Version of Intel Advisor

Also we could observe that you are using a .dat file in the command. Can you please change that .dat file to an executable file of your application and do the analysis.

Let us know the updates .


Regards,

Raeesa

Hi,

The application is the stencil computation, having as input a file (input.dat) with information to perform the calculation.

Steps:

  1. compilation of code
  2. command usage: advisor --collect=roofline --profile-gpu --project-dir =. / -- ./stencil_code input.dat

Hi,


Could you please try roofline analysis with sample application in the folder <advisor-installation-directory>/2021.1.1/samples/en/C++/

Verify whether other types of analysis like survey analysis in advisor is running successfully using your stencil computation application.


Also, Please share the language of your application and the devcloud node you are using. It would be better if you could share the command you used to enter into devcloud node.

Hi,

With the example C++ mmult_Advisor works fine. 
When run only survey or tripcounts works but when try run both or only roofline get the error.
The application is in DPC++ .

Hi,


We tried roofline analysis on dpc++ matrix multiplication sample and also on another sample available with advisor without any error.

Could you please share the devcloud node you are using. It would be better if you could share the command you used to enter into devcloud node.

Also , check whether any result folder named like e0000 is created in the directory where you run the command.

Hi,

Command to access the node: qsub -I -l nodes=s001-n229:gpu:ppn=2 -d .

The e000 folder is created.
Sorry

Hi ,

 

We tried running roofline analysis with –profile-gpu on sample dpc++ matrix application in the same node that you provided and it ran successfully. We might need a reproducer code for further debugging as the issue is not with the gpu node or the advisor. Could you please share the stencil application or result folder with us ?
