@HPCpodcast-81: Matt Sieger of ORNL on “Discovery” after “Frontier”

What does a supercomputer center do when it’s operating two systems on the TOP-10 most powerful computers? Well, it starts planning for what’s next.  The center is Oak Ridge National Lab (ORNL), and that’s exactly what it is doing. We caught up with Matt Sieger, Project Director for the 6th iteration of the Oak Ridge Leadership Computing Facility (OLCF-6) to get a glimpse of the project, its objectives, status, and timelines.

Meet Discovery, the supercomputer that is being planned to succeed Frontier (the current #1 at 1.19 exaflops in 64 bits) while Summit (the current #7 at 148.8 64-bit petaflops) continues to work alongside it.

With a Ph.D. in Physics from the University of Illinois at Urbana-Champaign and stints at the Pacific Northwest National Laboratory (PNNL), Intel’s fabrication facilities in Portland, Oregon, and a Knoxville-based startup as Chief Software Architect, Matt joined ORNL in 2009. He moved to OLCF as Deputy Project Director for the Frontier project in 2018, and was selected to lead the effort to procure the successor to Frontier in 2021.
