Vtune Devcloud Admin Permission Issue

bxbxf · ‎11-28-2022

I am trying to use Vtune for my FPGA project and it gives me error with missing sampling drivers I have followed this guide

https://www.intel.com/content/www/us/en/develop/documentation/vtune-cookbook/top/configuration-recipes/vtune-profiler-server-in-hpc.html

and also found this message sent by @JaideepK_Intel on different topic but I don't have admin rights

https://community.intel.com/t5/Analyzers/VTune-Profiler-execution-error/m-p/1385175/highlight/true#M22180

The error message :

vtune: Error: Cannot start data collection because the scope of ptrace system call is limited. To enable profiling, please set /proc/sys/kernel/yama/ptrace_scope to 0. To make this change permanent, set kernel.yama.ptrace_scope to 0 in /etc/sysctl.d/10-ptrace.conf and reboot the machine.
vtune: Warning: Microarchitecture performance insights will not be available. Make sure the sampling driver is installed and enabled on your system.

In order to install the sampling drivers I tried to use command ./build_drivers inside the folder vtune/sepdk/src but the action requires admin rights. I copied this folder to my own directory. The build was done but this time I couldn't load drivers again admin rights issue
