Live programming in scientific simulation

Abstract

We demonstrate that a live-programming environment can be used to harness and add runtime interactivity to scientific simulation codes. Through a set of examples using a Particle-In-Cell (PIC) simulation framework we show how the real-time, human-in-the-loop interactivity of liveprogramming can be incorporated into traditional "offline" and development workflows.We discuss how live programming tools and techniques can be productively integrated into the existing HPC landscape to increase productivity and enhance exploration and discovery.
