EC measuring library

[rvandernoort]

Summary

Currently, the implementation uses the PyJoules library for energy consumption measurements. It allows for both RAPL and NVML measurements on small functions with little overhead. Other measurements libraries like CodeCarbon and Eco2AI allow for the same type of measurements and are more recently maintained, however, they introduce such a large overhead that it significantly increases the runtime of the PyTorch model training. This is undesired and therefore no other EC measuring library is currently implemented, although GATorch is built such that it can be easily extended with other implementations.

Roadmap

• Investigate PyJoules' accuracy and overhead
• Investigate other EC measuring libraries
• Introduce new libraries if overhead is not a problem.
