Highlights of the 67th TOP500 List including Awarding

This session presents the 67th TOP500 list, hosted by Horst Simon (ADIA Lab) with Jack Dongarra (University of Tennessee, Oak Ridge National Laboratory) and Erich Strohmaier (Lawrence Berkeley National Laboratory). The headline is a new number one: LionShine, at the National Supercomputing Center in Shenzhen, China, delivering nearly 2.2 exaFLOPS on HPL and also topping HPCG. Chief designer Yutong Lu describes its CPU-only architecture built on the LX2 manycore Arm processor with on-chip matrix acceleration, integrated HBM, a four-layer fat-tree interconnect scalable beyond 100,000 nodes, full liquid cooling, and a self-developed software stack, achieving about 80% HPL efficiency. El Capitan and Frontier follow at positions two and three, JUPITER Booster at Forschungszentrum Juelich remains Europe's number one, and Aurora leads alongside El Capitan on HPL-MXP. Christine Harvey, chair of ACM SIGHPC, announces that ownership of the TOP500 will transition from the ISC Group to ACM SIGHPC, with the list remaining free, vendor-neutral, and published at ISC and SC, gaining DOIs in the ACM Digital Library. Strohmaier's analysis notes 44 new systems adding 21% performance, Italy surpassing Germany in installed performance thanks to two large Eni systems, slowing growth at the bottom of the list, only one new US system reported, growing Arm adoption, Blackwell systems entering while Hopper still carries most NVIDIA performance, and an unchanged Green500 top ten.
