- Abstract
- Intermittent computing enables the functioning of computing systems under unstable power conditions. Designing such systems poses significant challenges due to the vast design space, including hardware and software parameters along with harvested energy availability. In this paper, we propose an analytical framework to predict an application's execution time in intermittently powered systems, enabling rapid design space exploration. Our framework accounts for previously unexplored factors such as the effect of Equivalent Series Resistance (ESR) in capacitors and the choice of checkpoint strategies. With only one-time profiling, it estimates timings of different checkpoint techniques under various design configurations, with an average error of 4.7% under stable power and 10.4% under intermittent power. Furthermore, our evaluation reveals that neglecting checkpoint strategy in design can result in a 3.08x average slowdown compared to optimal setups.
