I read "Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 3".
Then, in it , I found that RAPL can estimate processors and DIMMs energy.
Also, I found that RAPL can limit power which processors and DIMMs consume.
After that, I looked for information about RAPL.then I found the paper named "RAPL:Memory Power Estimation and Capping", and I read it.
I have a couple of questions about RAPL.
The paper named "RAPL:Memory Power Estimation and Capping" written in 2010 refers "Memory Power Model", which is "Power = W(act)*A + W(read)*R + W(write)*W + W(cke_h)*CKE_H(adder) + K".
However, this paper doesn't mention "Package Power Model".
How is package power estimated ? I'd like to know Package Power Model. Let me know the paper about package or equality of package power model.
The paper named "RAPL:Memory Power Estimation and Capping" refers how RAPL caps DRAM power. However, it doesn't mention how RAPL caps package power.
How is package power capped ? Is DVFS or something used?
