LineShine, an exaflop without GPUs........................................................................................................................................................................................................2026.11.07

The June 2026 TOP500 number one, taken apart: the LX2 chip, its matrix units, two memory tiers, the LingQi network, the software, and what the benchmarks really say.

Working on a shared cluster........................................................................................................................................................................................................2026.09.08

Login, modules, a job that finishes, then a first GPU kernel. One note, four pages.
