【Abstract】As for the scale of the problem and the system continues to expand, the cluster-based high-performance computer is facing scalability,
reliability, power consumption, footprint, balance, and many other challenges. This paper introduces the design and realization of high-productivity
computing node such as computing module, switch module, management module, adaptive power management, FPGA-based hardware accelerator
board, high-speed PCI-E switch extend module and other aspects. It resolves the computing density, I/O expansion and bandwidth bottleneck as well
as energy consumption and other bottlenecks in Dawning 5000A 100 Teraflops supercomputer based on the high-productivity computing node.
【Key words】high-productivity; energy saving; hardware accelerate
