A Look Inside China’s Chart-Topping New Supercomputer

The SW26010 and the Sunway TaihuLight system has been engineered for super-efficient floating point performance. This creates a total of 260 cores per unit and it’s built from there. Four of those go in a cabinet, and the full system stretches to forty cabinets total with an interconnect that’s built into the chip (which is referred to as the custom ‘network on a chip” interconnect) and also an interconnect for hooking everything together to form a supernode. “Sunway has built their own interconnect. The efficiency figures below are for the LINPACK benchmark and count processor, memory, and the interconnect.
