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.
