Hello,
I am running the following commands on VTune:
vtune -collect memory-access --result-dir my_dir my_app > my_dir/log.out
vtune -report hw-events -r my_dir -report-output my_dir/events.csv -format csv -csv-delimiter comma

It looks like VTune doesn't use the SEP driver. Have you checked if your VTune driver is ready?

If your application was built as a debug version? and please try with specifying '-search-dir' and '-source-search-dir'.

Hello @yuzhang3_intel
Thank you for your reply.
The application was built using the debug flag -g3. I tried specifying '-search-dir' and '-source-search-dir', but the result does not change.
Do you have any other suggestion?
Thank you!

Not sure what causes the module not parsed. Could you please post the collection type the VTune used for the memory access profiling? You can get the 'Collector Type' from the summary report .
$ vtune -R summary -r your_vtune_data

Hello @yuzhang3_intel
I have checked and it seems SEP driver is not installed, even though I can see the SEP application installed on the system.
I tried to run the insmod-sep binary from the VTune folder, but I do not have the permissions to execute it since I am using a node on a computing cluster.
Do you know if there is a way to use SEP functionality from user level?
Thank you!

No, the .ko drivers are required to be inserted into the kernel.
