“Navigating the Post-Exascale Computing Era: GPUs, Analog Computing, and AI”
19 February 2025
Abstract
DOE has deployed its first three Exascale systems, so now is an appropriate time to think about post-Exascale challenges and opportunities. GPUs were just the beginning of architectural disruption. Focusing on both performance and energy efficiency, we are seeing a wide array of new technologies emerge during this ‘golden age of architectures,’ making the choices of architectures, software, and applications existential. In this talk, I will survey post-Exascale technologies and discuss their implications for both system design and software. As an example, I will delve into analog computing as one alternative to dramatically improve energy efficiency. Meanwhile, the extraordinary disruption offered by AI may provide ways to mitigate these software and algorithmic challenges. Our team is exploring how AI can be used to port software to new architectures and transform legacy programming languages to contemporary programming systems.

“Deep Codesign in the Post-Exascale Computing Era”
Wednesday 15 February 2023, 3.45pm – 4.20pm
Abstract
DOE has just deployed its first Exascale system at ORNL, so now is an appropriate time to revisit our Exascale predictions from over a decade ago and think about post-Exascale. We are now seeing a Cambrian explosion of new technologies during this ‘golden age of architectures,’ making codesign of architectures with software and applications more critical than ever. In this talk, I will revisit Exascale trajectory, survey post-Exascale technologies, and discuss their implications for both system design and software. As an example, I will describe Abisko, a new microelectronics codesign project, that focuses on designing a chiplet for analog spiking neural networks using novel neuromorphic materials.
