Aurora exascale supercomputer architecture at Argonne detailed

Argonne National Laboratory and collaborators describe the architecture and software ecosystem of Aurora, the lab’s first exascale supercomputer, in a 40-page paper submitted to J. Supercomputing.

• The paper details Aurora’s node architecture, including Intel Xeon Data Center GPU Max Series (Sapphire Rapids) with HBM, Intel Data Center GPU Max Series (Ponte Vecchio) on each compute node, HPE Slingshot interconnect, and integration of Distributed Asynchronous Object Storage (DAOS) and Intel oneAPI.
• It reports on standard benchmark performance and application readiness via Aurora’s Early Science Program and the Exascale Computing Project, with the article hosted on arXiv (arXiv:2509.08207, DOI 10.48550/arXiv.2509.08207) and revised to version v2 on 8 Dec 2025.
