Use of Arm cores and Linux mean Beijing hasn\u2019t broken away from the world<\/p>\n

The TOP500 list of Earth\u2019s mightiest supercomputers has a new leader: the 2.198 Exaflop\/s LineShine machine housed at the National Supercomputer Center (NSC) in Shenzhen, which took the top spot without using any kit from Nvidia, Intel, or AMD.<\/p>\n

Which is not to say that LineShine is an entirely Chinese creation. As explained in a pre-press paper, the machine\u2019s LX2 processors are a local effort but use Armv9 designs \u2013 so chalk up a win for Blighty, the home of Arm. The machine also runs KylinOS \u2013 a Linux distribution that features contributions from around the world.<\/p>\n

The paper reveals that LineShine comprises 20,480 computing nodes, and that each LX2 processor \u201cintegrates two compute dies (304 cores total) and eight on-package HBM stacks (32 GB, 4 TB\/s aggregate bandwidth).\u201d<\/p>\n

\u201cEach compute die contains 152 cores and 128 GB of off-package DDR memory organized into four NUMA domains,\u201d the paper adds. \u201cA dedicated SDMA engine handles data movement between DDR and HBM. The LX2 supports FP64\/FP32\/FP16\/INT8 via SME and SVE units, delivering up to 60.3\/120.6 TFLOPS in FP64\/FP32. Nodes are interconnected via the LingQi high-speed network with a dual-plane multi-rail fat-tree topology, offering 1.6 Tb\/s bandwidth per node.\u201d<\/p>\n

That network is also a Chinese creation, from the minds at Hangzhou LingQi Technology Co.<\/p>\n

LineShine became the first system on the TOP500 to exceed two exaflops of sustained double-precision performance using CPUs only and the curators of the list think it could do better in future tests, because this time around it reached about 80 percent of its 2.736 Exaflop\/s theoretical peak in tests conducted in preparation for this iteration of the TOP500 list.<\/p>\n

News that LineShine topped the supercomputing charts comes as China\u2019s government increasingly steers local organizations towards…<\/p>\n
