Intel Vtune Ampilfier memory analysis issue

Hi All,

Running code in CRAY XC 40 machine.

When I'm doing memory access getting error at run time

amplxe: Error: This analysis type requires either an access to system-wide monitoring in the Linux perf subsystem or installation of the VTune Amplifier drivers (see the "Sampling Drivers" help topic for further details). Please set the /proc/sys/kernel/perf_event_paranoid value to 0 or less to continue without installing the drivers.

If I change the value in the /proc/sys/kernel/perf_event_paranoid to 0 or less it will effect performance of others who are running jobs in the nodes?

When I'm doing hotsopts analysis it is not giving any error.

Please give me suggestions

The perf_event_paranoid should not affect performance of other users. It will only have security implications.
