KUALA LUMPUR (Nov 15): The US Department of Energy's 1.1 exaflop Frontier machine at Oak Ridge National Lab continued to hold the number one spot as the world's fastest supercomputer in a twice-yearly ranking by international experts.

In the ranking released on Monday (Nov 14), the US Frontier system, Japan's Fugaku, and EuroHPC's LUMI held steadfast as the top three spots.

Similar to Frontier, LUMI is based on an all-AMD architecture built by Cray that pairs optimized 64-core Epyc 3 Milan CPUs and Instinct MI250x GPUs with HPE's Slingshot-11 NICs.

Since its initial appearance as the third most powerful supercomputer on the Top500 in spring, the system has grown from 1.1 million cores to more than two million, demonstrating near-linear scaling at 309 petaflops of double-precision performance.

Meanwhile, Italy's newly minted 174-petaflop Leonardo system, which now claims the title as the fourth most powerful supercomputer on the Top500 and the second most powerful system in Europe behind LUMI.

Based on Atos's BullSequana XH2000 platform, Leonardo pairs 1.4 million third-gen Intel Xeon Platinum cores with Nvidia's A100 40GB GPUs and 100Gbps InfiniBand NICs.
