Energy capture of time-varying energy sources by varying computational workload

摘要

A method and system for managing computational workload in a computerized system powered by an energy source. This invention relies first and foremost on adapting computational workload at the computerized system according to a time-varying property of the power supplied by the energy source, such that power generated at the source is optimized. A feedback mechanism is accordingly implemented which changes power available for computation, e.g., to track a more efficient energy generation efficiency point at the source.
