Aurora (Intel-HPE): Website
Aurora, Argonne’s first exascale computer, features Intel’s Data Center GPU Max Series GPUs and Intel XEON Max Series CPUs with HBM, a CPU-GPU interconnect (PCI-e), the HPE Slingshot fabric system interconnect, and a Cray EX platform. Aurora will featur several technological innovations and will also include a revolutionary I/O system – the Distributed Asynchronous Object Store (DAOS) – to support new types of machine learning and data science workloads alongside traditional modeling and simulation workloads.
