I run Ubuntu 20.04 on a Lenovo ThinkPad and just installed OneAPI with C and Fortran compilers, MKL and VTune. When I ran VTune on an MPI code, I got the message:
"This analysis requires one of these actions: a) Install Intel Sampling Drivers. b) Configure driverless collection with Perf system-wide profiling. To enable Perf system-wide profiling, set /proc/sys/kernel/perf_event_paranoid to 1 or set up Perf tool capabilities."
I tried option a) by following the instructions here:
and those in /opt/intel//oneapi/vtune/latest/sepdk/src/README
and all scripts finished without error messages. However, when I run
> insmod-sep -q
pax driver is loaded and owned by group "users" with file permissions "660".
socperf3 driver is not correctly loaded.
sep5 driver is not correctly loaded.
socwatch driver is loaded and owned by group "users" with file permissions "660".
vtsspp driver is loaded and owned by group "users" with file permissions "660".
It appears that "socperf3" and "sep5" are broken somehow, or it could be a problem with the "groups" and permissions. Any help would be appreciated!

Update: I used "usermod" to add myself to groups "vtune" and "users", then re-booted. Perhaps some other changes had been pending. Now, I see:
>./insmod-sep -q
pax driver is loaded and owned by group "users" with file permissions "660".
socperf3 driver is loaded and owned by group "users" with file permissions "660".
sep5 driver is loaded and owned by group "users" with file permissions "660".
socwatch driver is loaded and owned by group "users" with file permissions "660".
vtsspp driver is loaded and owned by group "users" with file permissions "660".
Ansd VTune seems to work! Not quite sure what did the trick TBH.
