MPI Roofline analysis doesn't work on Icelake architecture

MPI roofline analysis is two step process where the first one is to generate survey followed by tripcounts.

The survey analysis works OK, but when tripcounts are run over the result from survey, the following errors are seen.

advixe: Opening result 25 % done
advixe: Preparing frequently used data 0 % done
advixe: Preparing frequently used data 100 % done
advixe: Collection started.
advixe: Error: Internal error. Please contact Intel customer support team.
advixe: Error: Analysis terminated abnormally.
advixe: Error: An internal error has occurred. Our apologies for this inconvenience. Please gather a description of the steps leading up to the problem and contact the Intel customer support team.
advixe: Warning: The application returned a non-zero exit value.
advixe: Opening result 23 % Loading 'tripcounts_5326_0.tcs' file
advixe: Error: Cannot load data file `./dgl/rank.1/hs000/data.1/tripcounts_5326_0.tcs' (Data file is corrupted).

This problem is seen only in Icelake, works fine on cascadelake.

This is using OneAPI Advisor v2021.4.0

Thanks

Hi,

Could you please share a sample reproducer, so we can try that from our end.

Thanks,

Hi,

I tried to run MPI roofline analysis (both survey and tripcounts) on vector addition sample and it works fine.

Specifications:

Processor : Intel(R) Xeon(R) Platinum 8358 (Ice Lake)

OS : Ubuntu 20.04.3 LTS

Advisor version: 2021.4 (Latest)

Maybe there is an issue with the sample, could you please share a sample reproducer, so we can try that from our end.
