Arm in HPC: Where We Are Today and Where We Are Heading Tomorrow

Arm technology has increasingly become a mainstream choice for HPC due to its promise of higher efficiency, density, scalability, and a broad ecosystem of software. Arm expansion in the data center started in 2018 with Arm Neoverse, a set of infrastructure CPU IPs designed for high-end computing. The Arm-based Fugaku supercomputer, #1 in the June 2020 Top 500 ranking for 2 years, retained a leadership position over multiple years. This event has been a wake-up call for the HPC community. The ecosystem is finally mature enough to begin diversifying beyond x86 and re-create a vibrant multi-architecture HPC ecosystem as it was more than a decade ago. Arm technology is at the forefront of this wave of change with present products like AWS Graviton and NVIDIA Grace. This BoF aims to bring together a growing community of leaders and practitioners who decided, either on-prem or in the cloud, to adopt Arm-technology for their current or future production systems. Primed by a short opening session from early adopters and cloud pioneers, the participants will have the opportunity to share and discuss their experiences, provoke thoughtful comparisons about Arm versus x86 at all levels, identify and together address community needs for training and education at multiple levels, and (last but not least) share must-have/wish-have about the future of Arm in HPC with technology providers and user facility representatives. We seek to provide a venue where the community can meet up to bootstrap collaborations, find mentorship opportunities, and engage in fruitful technical discussions.
