Intel Unveils Full Aurora Supercomputer Specifications: 21,248 Xeon CPUs & 63,744 GPUs For Over 2 ExaFlops

wccftech.com:

Intel has finally unveiled the full specifications of the Aurora supercomputer designed for the Argonne National Laboratory in the US.

In the latest disclosure, Intel revealed that the Aurora supercomputer will be packing a total of 10,624 Nodes which include a mammoth 21,248 Xeon CPUs based on the Sapphire Rapids-SP family and 63,744 GPUs based on the Ponte Vecchio design. This system will be a beast with an insane fabric interconnect that offers a peak injection bandwidth of 2.12 PB/s & a peak bisection bandwidth of 0.69 PB/s.

Argonne is spearheading an international collaboration to advance the project, including Intel; HPE; Department of Energy laboratories; U.S. and international universities; nonprofits; & international partners, such as RIKEN.

Additionally, Intel and Argonne National Laboratory highlighted installation progress, system specs and early performance results for Aurora:

Aurora is expected to offer more than 2 exaflops of peak double-precision compute performance when launched this year.

For memory, the Aurora supercomputer is outfitted with 10.9 PB of DDR5 system DRAM, 1.36 PB of HBM capacity through the CPUs, and 8.16 PB of HBM capacity through the GPUs. The system DRAM achieves a peak bandwidth of 5.95 PB/s, the CPU HBM achieves a peak bandwidth of 30.5 PB/s and the GPU HBM achieves a peak bandwidth of 208.9 PB/s. For storage, the system is equipped with a 230 PB DAOS capacity that runs at a peak bandwidth of 31 TB/s & is configured in a total of 1024 nodes.

Aurora running the latest Intel Data Center GPU Max Series 1550 offers the fastest SimpleFOMP performance, outclassing the NVIDIA A100 and AMD Instinct MI250X accelerators. Intel also touts some impressive relative performance versus those
