Design of Cloud Server Based on Godson Processors

Compared with the existing cloud computing systems based on high-performance processors and traditional Ethernet network, a 32 Godson processors cloud computing system based on HyperTransport switch (HT switch) is presented in this paper, which uses HT switch as its interconnection fabric. HT switch makes it possible to build a high performance-cost ratio, and high performance-watt ratio cloud server based on Godson processors, to better meet the requirements of cloud computing workloads. As a key interconnection fabric used to construct the cloud server, the HT switch architecture is discussed in details. To evaluate the performance of HT switch-based multiprocessor systems, a prototyping system followed by results of performance testing is implemented.
