  • Since this article is very light on details-

    It’s using Huawei LX2 ARMv9 cores, 304 cores @1.5ghz 690W (with 1x? SVE2 unit and an SME unit, nice) with two seats per node, originally it was to have 20,480 nodes in 90 cabinets for 40,960 CPUs (12,451,840 cores…) but the TOP500 listing has more cores (13,789,440 - 4,400 more) than some of the original documentation, so they must have added a few cabinets.

    Pretty neat, brute-forcing it with CPUs makes for an infinitely more useful machine than GPU compute, despite the higher power cost. (42MW vs. 29MW for El Capitan)









  • Why not go the opposite direction entirely?

    Grid scale batteries would be better served by Nickel-Iron batteries with pumped electrolyte. They don’t have a fire risk like Li-ion and can be discharged to 0% without damage. The downside is the electrolyte needs changing frequently (daily to weekly) but for a grid scale battery bank, that isn’t an issue, just trickle through new electrolyte at a constant rate.

    It’s not a solution for vehicles or portable devices, but for big batteries we shouldn’t be looking at solid state.
