- RAPL analysis tests on a laptop - Intel Communities
Hi, I am testing the RAPL feature a laptop in a way to try to read some CPU consumption values and I need someone to help me getting some answers Well, I am running a RAPL sample code simultaneously with a total battery power consumption code and I am getting the following values: ##RAPL: Package e
- RAPL PP0 supported but not enabled - Intel Communities
We would like to inform that for management of RAPL you can use Intel® Speed Select Technology - Core Power (Intel® SST-CP) which is the fundamental building block that enables the Intel® SST-BF and Intel® SST-TF features
- RAPL: Intel(R) Xeon(R) Silver 4112 CPU monitoring
Intel's RAPL power monitoring facility does not support monitoring of individual cores Depending on the processor model you can monitor the power used by *all* cores in a socket, the power used by all the DRAM attached to a socket, the power used by everything in the socket, and for some client processors the power used by uncore devices (like an embedded GPU)
- RAPL for energy measurement - Intel Community
Hi guys, To my understanding, there are 4 interfaces defined by MSR to measure the energy consumption: PKG (package power), PP0 (core), PP1 (uncore) and DRAM To my understanding, PKG = PP0 + PP1, and PP1 includes the power consumption of the LLC, intergrated graphic card and many other uncore stuff
- Solved: DRAM RAPL Issue - Intel Community
The BIOS sets DDR RAPL mode though BIOS-to-Pcode Mailbox command In this case you may Set DRAM only, the power consumption of the main memory In regards to DRAM RAPL modes you have two options: DRAM RAPL MODE0=DRAM power from pure activity based estimation and DRAM RAPL MODE1= DRAM power from scaling activity-based estimation to match DDR VR
- set power limit to DRAM with RAPL - Intel Community

- What is the formula for total energy based on RAPL domains
Hello, I would like to understand what a proper formula, based on RAPL domains, would be to calculate the total amount of energy the CPU reports (including CPU, GPU, DDR, etc ) Let's suppose that "$ powercap-info -p intel-rapl" reports the following zones:Zone 0 -- name: package-0 -- Zone 0:0 ---
- RAPL on Skylake-X - Intel Community
( sudo modprobe intel-rapl ) The folder intel_rapl:0 contains the package power zone If you enter in this folder there are all the files needed to power-cap the core The file that shows the consumed energy is (obviously) energy_uj The subfolder of intel_rapl:0 (intel_rapl:0:0, intel_rapl:0:1, intel_rapl:0:2) are the subzones
