Under the alliance agreement between Cray and Fujitsu, Cray is developing the first-ever commercial supercomputer powered by the Fujitsu A64FX Arm-based processor with high-memory bandwidth (HBM) and supported on the proven Cray CS500 supercomputer architecture and programming environment.
Initial customers include Los Alamos National Laboratory, Oak Ridge National Laboratory, RIKEN Center for Computational Science, Stony Brook University, and University of Bristol. As part of this new partnership, the companies will explore engineering collaboration, co-development, and joint go-to-market in an effort to meet customer demand in the supercomputing space.
Cray customers are leaders in their respective fields and often look for opportunities to gain the next edge in performance. The new Fujitsu processor is unique in that it is the first processor to deliver HBM and Arm Scalable Vector Extensions (SVE). HBM2 provides transfer speeds that are significantly faster than DDR4 giving the A64FX a maximum theoretical memory bandwidth greater than 1 terabyte per second (TB/s), and support for Arm SVE provides improved performance for artificial intelligence and analytics.
The Cray CS500 system can apply this compute power to a wide range of HPC and AI workloads while still delivering hallmark features of Arm-based systems with high parallelization, low power consumption and high reliability.
The Cray supercomputer powered by Fujitsu A64FX Arm will be available through Cray to customers in mid 2020.
