VTune analysis of MPI program on linux fails

[hbu]

Hi all,

I am having trouble to run an MPI analysis with VTune on linux. I am trying to run

srun vtune -collect hpc-performance –r vtune_mpi -- ./my_app

The error I am getting looks like

vtune: Error: Preliminary validation of the requested events failed.
vtune: Internal Error
vtune: Internal Error
vtune: Internal Error
vtune: Error: amplxe-perf:

I attach the error log (slurm_Error.txt) and the log of the self-check (self-check_log.txt).

Thank you!

From the log, the SEP driver doesn't work. Could you install the driver manually? The current release is 2024.1, I suggest you upgrade the VTune version to the latest one.

Check driver:
isSEPDriverAvailable: false
isPAXDriverLoaded: false
Command line:
lsmod

Is SEP in lsmod: False
The SEP driver is not available.
================================================================================
SEP version:
Command line:
/opt/intel/oneapi/vtune/2023.0.0/bin64/sep -version
Stdout:

SEP Driver Version: PAX Driver Version: Platform type: 127

Stderr:

Check driver with sep -version: Fail

I followed https://www.intel.com/content/www/us/en/docs/vtune-profiler/user-guide/2023-0/build-install-sampling-drivers-for-linux-targets.html and did the following

yum install elfutils-libelf-devel
cd /opt/intel/oneapi/vtune/2023.0.0/sepdk/src
./build-driver
./insmod-sep -r -g my_group

Now I get

/opt/intel/oneapi/vtune/2023.0.0/bin64/sep -version
Sampling Enabling Product Version: 5.38 Beta built on Dec  6 2022 03:53:32

The hpc-performance analysis runs fine now.

Thank you!
