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
