Optimizations of Two Compute-Bound Scientific Kernels on the SW26010 Many-Core Processor

The home-grown SW26010 many-core processor enabled the production of China's first independently developed number-one ranked supercomputer - the Sunway TaihuLight. The design of the limited off-chip memory bandwidth, however, renders the SW26010 a highly memory-bound processor. To compensate for this limitation, the processor was designed with a unique hardware feature, "Register Level Communication" (RLC), to share register data among its 8 × 8...
