THREAD MODE EXAMPLE:

perf-stat reports the scaled counts for hybrid event and with a
       percentage displayed. The percentage is the event's running
       time/enabling time.

       One example, triad_loop runs on cpu16 (atom core), while we can
       see the scaled value for core cycles is 160,444,092 and the
       percentage is 0.47%.

       perf stat -e cycles — taskset -c 16 ./triad_loop

       As previous, two events are created.

           perf_event_attr:
             size                             120
