Installing sampling driver

Hi,

I am profiling my code with VTune on the devcloud. My profiling results shows that it is using driverless perf system-wide sampling. Insteaad, I would like VTune to use the hardware event-based sampling using the sampling driver that is usually installed in the system. Here:

https://software.intel.com/content/www/us/en/develop/documentation/vtune-help/top/set-up-analysis-ta...

I have seen some instructions to install the driver, but I couldn't be sure if I should follow them. 

Is it possible to install and use the sampling driver on devcloud for Intel VTune analysis? If so,  should I simply follow the instructions on the link, or should I do something else?

Thank you very much,

Best regards,

Utku Sirin

Hi Utku Sirin,


The installation and loading of sampling drivers would require root/sudo level permissions. As devcloud users are not allowed these permissions you wouldnt be able to build/load sampling drivers. We will check with admin team if its feasible to load the sampling drivers from their end . Will let you know as soon as we have an update.


Thanks

We are checking on this internally, will soon get back to you when we have an update from devcloud admin team.
