ARCHER Webinar: Isambard: tales from the world's first Arm-based supercomputer
James Price, University of Bristol
The Isambard Project, a GW4 Alliance initiative, has evaluated the performance of its Arm-based processors for HPC, the first such results available for dual socket Cavium ThunderX2 nodes. James Price will describe the results of a detailed performance comparison between Cavium ThunderX2 Arm-based CPUs with the latest state-of-the-art Skylake x86 processors. Results focus on the HPC codes that are most heavily used on the UK’s national supercomputer, ARCHER, and show that for these kinds of workloads, ThunderX2 is competitive with the best x86 CPUs available today but with a significant cost advantage.
