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.
