This feature currently requires superuser privileges, as registers are queried.
Only use this feature with code you trust! Call smpirun for instance via
smpirun -wrapper "sudo " <your-parameters>
+ or run sudo sh -c "echo 0 > /proc/sys/kernel/perf_event_paranoid"
+ In the later case, sudo will not be required.
\note
This option is only available when SimGrid was compiled with PAPI support.
