Performance per watt is a measure that evaluates the efficiency of a computing system by comparing the amount of computational work done to the amount of power consumed. This metric is crucial in the design and operation of advanced computing systems, especially as energy costs rise and environmental considerations grow. A higher performance per watt indicates a more efficient system, allowing for improved energy-aware scheduling and resource management, effective hardware-level power management techniques, and overcoming power consumption challenges faced by exascale systems.
