PMU name: rapl
PMU desc: Intel RAPL (Intel SandyBridge, IvyBridge, Haswell)
DESCRIPTIONThe 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:
On all processors, the event reports the number of Joules consumed by all cores.
On all processors,
- On all processors, th event reports the number of Joules consumed by all the cores and Last Level cache (L3).
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.
MODIFIERSThe PMU does not support any modifiers.
