… Woopsy! … they of course used Large Eddy Simulation (LES), not RANS! … and (obviously) TNP detailed the SW26010-Pro chip of the Sunway supercomputer last year (03/11/22) — but maybe the SACA accelerator is a new item added since then.

At the SC23 Denver (Nov.12-17) website (https://sc23.supercomputing.org) they now list the 2023 Gordon Bell Prize Finalists, which include a team from China+UK+US (including National Supercomputing Center in Wuxi and UIUC/NCSA) for their work: “Towards Exascale Computation for Turbomachinery Flows” (available on arxiv.org) — NASA’s grand challenge problem.

They achieved a sustained 116 PF/s (FP64) on their Sunway supercomputer: “The system consists of over 100,000 SW26010 pro chips with a theoretical peak performance of 1.5 EFLOPS.” (page 4). The paper has very nice illustrations of their solution of the Reynolds-Averaged Navier-Stokes (RANS) equations.

So, a nice system, somewhere between #6 Sierra (95 PF/s sustained) and #1 Frontier (1.7 EF/s peak). Schrumour has it the team submitted a HPL-MxP score of 5 EF/s for the November list — in the June ’23 list the top 5 systems had MxPs of 2 to 10 EF/s.

They had the Opteron-based #2 Titan, at 18 PF/s (2.2 GF/W), to the Xeon-based #1 Tianhe-2A, at 34 PF/s (1.9 GF/W). Their VPS went up to 46% in 2015 (around HP/HPE unmerge time), then down to 17% in 2021 (couple years after Cray aquisition) and is now back up to 44% in 2023, with the EPYC-based #1 Frontier, at 1.2 EF/s (52. GF/W). It was a bit of a roller-coasting decade but HPE-Cray seems to have now reached a stable (and impressive) stride. The swashbuckling old-spice stronger swagger of El Capitan should definitely contribute nicely to this (in addition to “Intelligent Edge” products)!

This does however raise the question of the missing Chinese Exafloppers … whatever happened to those?
