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:
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,
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.
