Interactive and Urgent HPC: State of the Research
It addresses the growing need for HPC systems to support interactive and urgent applications, which is incremental as it builds on existing HPC research.
This chapter surveys the emerging trend of interactive and urgent computing in high-performance computing (HPC), covering applications like simulations and machine learning that demand both high parallelism and real-time responsiveness, while outlining future directions for integrating these capabilities into HPC ecosystems.
When we think of how we use smartphones, e-commerce, collaboration platforms, LLMs, etc., most of our interactions with computers are interactive and often urgent. Similar trends of interactivity and urgency are coming to HPC, with applications from simulations to data analysis and machine learning requiring more parallel computational capability and more interactivity. This chapter overviews the progress made so far along with some vectors of what the path forward will bring for greater integration of interactive and urgent HPC policies, techniques, and technologies into our HPC ecosystems.
