NAME

       libpfm_intel_rapl - support for Intel RAPL PMU

SYNOPSIS

       #include <perfmon/pfmlib.h>

       PMU name: rapl
       PMU desc: Intel RAPL (Intel SandyBridge, IvyBridge, Haswell)

DESCRIPTION

       The  library supports the Intel Running Average Power Limit (RAPL) energy consumption counters. This is a
       socket-level set of counters which reports energy consumption in Joules. There are up to 3 counters  each
       measuring only one event. The following events are defined:

       RAPL_ENERGY_CORES
              On all processors, the event reports the number of Joules consumed by all cores.
               On all processors,

       RAPL_ENERGYC_PKG
              On  all processors, th event reports the number of Joules consumed by all the cores and Last Level
              cache (L3).

       RAPL_ENERGY_DRAM
              On server processors, the event reports the number of Joules consumed n by the DRAM controller.

              By construction, the events are socket-level and can only be measured in system-wide mode.  It  is
              necessary and sufficient to measure only one CPU per socket to get meaningful results.

MODIFIERS

       The PMU does not support any modifiers.
