 # CPU Model
 [cpu_model.csv](./cpu_model.csv) relates CPU model family found in `/proc/cpuinfo` to its architecture.

-# Power Data
-[power_data.csv](./power_data.csv) is retrieved from [Cloud Carbon Footprint](https://github.com/cloud-carbon-footprint/cloud-carbon-coefficients), as an estimate of energy consumption per CPU thread and GB DRAM.
