Abstract:

In recent years, systems based on the Arm architecture have gained traction in the HPC community as evidenced by several Arm-based projects including the Japanese Post-K Fugaku Computer, Sandia’s Astra system, UK’s GW4/EPSRC efforts, and Europe’s Mont-Blanc project. Arm is now a major player in the HPC field, by introducing new technologies for HPC workloads like Armv8-A Scalable Vector Extension (SVE) technology and related compilers and scientific libraries. 2021 also marks the 2nd year of the Fujitsu A64FX processor with Arm SVE hardware currently being deployed in systems like Astra, Fugaku, Ookami, and Isambard.

In this BoF we will discuss user experiences with some of these new Arm HPC systems and related commercial deployments. We will also examine how the newly formed Arm HPC User Group (AHUG) can support efforts to grow the Arm HPC community as we look towards the second generation of Arm systems with SVE2 support, AI support, and more tightly coupled accelerators like GPUs. This BoF will provide time to pose questions on where Arm-based deployments are headed and to discuss how we would like the Arm HPC community to grow to support these new efforts.
