Rapl:::PACKAGE_ENERGY:PACKAGE0 1.150513 J (Average Power 1.2W ) Stopping measurements, took 1.000s, gathering results. # chih archlinux in ~/PMU/papi-5.5.1/src/components/rapl/tests Not that you cannot get readings for individual processes, the results are for the entire CPU socket. Using raw-access to the underlying MSRs under /dev/msr.This requires root or a paranoid less than 1 (as do all system wide measurements with -a) sudo perf stat -a -e 'power/energy-cores/' /bin/ls Available events can be found via perf list or under /sys/bus/event_source/devices/power/events/ Using the perf_event interface with Linux 3.14 or newer.This requires no special permissions, and was introduced in Linux 3.13 Reading the files under /sys/class/powercap/intel-rapl/intel-rapl:0 using the powercap interface.There are currently three ways to read RAPL results using the Linux kernel:

Total Processor Energy_0 (Joules )= 17.8525Īverage Processor Power_0 (Watt )= 1.7800 System Time,RDTSC,Elapsed Time (sec ),IA Frequency_0 (MHz ),Processor Power_0 (Watt ),Cumulative Processor Energy_0 (Joules ),Cumulative Processor Energy_0 (mWh ),IA Power_0 (Watt ),Cumulative IA Energy_0 (Joules ),Cumulative IA Energy_0 (mWh ),GT Power_0 (Watt ),Cumulative GT Energy_0 (Joules ),Cumulative GT Energy_0 (mWh )

turbostat: PKG, PP0 and PP1 planes Linux.Ī model-specific register (MSR) is any of various control registers in the x86 instruction set used for debugging, program execution tracing, computer performance monitoring, and toggling certain CPU features.

Intel Power Gadget: PKG and PP0 planes Windows, Mac and Linux.mozilla_rapl: all planes Linux and Mac.Tools that can take RAPL readings include the following. DRAM is independent of the other three domains. The following relationship holds: PP0 + PP1 <= PKG. DRAM: main memory (not available on all processor models.).PP1: An uncore device, usually the GPU (not available on all processor models.).Recent (Sandy Bridge and later) Intel processors that implement the RAPL (Running Average Power Limit) interface that provides MSRs containing energy consumption estimates for up to four power planes or domains of a machine, as seen in the diagram above.

The part of the package outside the cores is called the uncore our system agent. It includes various components including the 元 cache, memory controller, and, for processors that have one, the integrated GPU.

Each core typically has hyper-threading, which means it contains two logical CPUs.

Xeon) typically have two or more packages. These are part of the actual processor that you buy from Intel.

The processor has one or more packages.

Based on our measurements, they match actual power measurements.

This software power model estimates energy usage by using hardware performance counters and I/O models. RAPL is not an analog power meter, but rather uses a software power model. RAPL provides a set of counters providing energy and power consumption information.
