## Summary
TODO
- We can see that the SDIA model in its current form cannot account for the idle state of the machine and thus always underestimates here
- The SDIA model underestimates 1-chip machines and greatly over-estimates 2-chip machines
+ Taken into account that for 2-chip machines we only have SPECPower data at the moment and no real world data
- The linear model is good for parameter exploration, but delivers badly fitted results
- The XGBoost model is able to estimate a real world 1-chip machine and an out of sample 2-chip machine from SPECPower very nicely.
+ However it tends to under-estimate
- We see suprisingly no efficiency gain from applying the SPECPower BIOS settings but rather a smoothing of the curve. The reason to that is currently unknown.

- Re-evaluating more machines from the SPECPower database in our lab and better understand what the BIOS settings really impact in regards to the server energy
- Research what values in the cloud are typically set for the BIOS settings that SPECPower lists and if they can be configured in the cloud
- Introspecting our models to understand which parameter in which setting will give the most energy gain when set on the machine so that developers can optimize these parameters
