In this interview conducted on behalf of HPC analyst firm Hyperion Research, we spoke with Argonne National Laboratory’s Rick Stevens about the present and future of HPC. The starting point for this conversation is a presentation Stevens gave at a Hyperion event in Washington related to implementation of the CHIPS and Science Act and includes his insights on the post-exascale build-out of an integrated network of U.S. supercomputing capacity (the Integrated Research Infrastructure, or IRI). We then look at AI for science and the use of data-driven modeling and simulation, which shows the potential to deliver major performance gains for researchers….
