Argonne National Laboratory’s Aurora was intended to be the first supercomputer with performance exceeding 1 exaflops, but after delays, the title was left to the Frontier supercomputer. However, Aurora will be the first 2 exaflops supercomputer thanks to Intel’s Ponte Vecchio GPU. The Ponte Vecchio will also power Europe’s first exascale system.
First announced in 2015, the Aurora Supercomputer would be powered by Intel’s Xeon Phi accelerators and would yield approximately 180 petaflops in 2018. But the blue camp scrapped its Xeon Phi in favor of GPUs and had to renegotiate the deal with Argonne National Laboratory and deliver an exaflops system in 2021.
After that, the company had to postpone delivery of the system again due to the delay in its 7nm process and the need to manufacture Ponte Vecchios both internally (using Intel 4) and externally (using TSMC’s N5 node).
Europe’s first supercomputers will use SiPearl’s Rhea-soc specially designed as part of the European Processor Initiative. The chip is expected to contain up to 72 Arm Neoverse Zeus cores interconnected via a mesh network, but an HPC accelerator is still needed to meet performance targets.
Intel’s Ponte Vecchio compute GPU will first be used for the Aurora supercomputer, but eventually it will power other high-performance computing systems as well.
