Energy harvesting allows computational devices to run without a battery, opening new application domains of computing. Such devices work under an intermittent computing model, where the system may power cycle several times a second. The main approach to ensuring progress in intermittent computing is to use checkpoints, with much work being dedicated to this direction. However, no existing approaches handle programs using dynamically allocated memory in the intermittent computing model. We pose this as a challenge area, demonstrate the complexities of checkpoint in this space, and propose key characteristics an effective solution.
