Research on High Performance Computer Technology Based on InfiniBand

The network performance is the key bottleneck which always restricts the development of high performance computing technology, whether computing network or storage network, the progress of communication is lag behind that of CPU. InfiniBand interconnection architecture can fill the performance gap in network and CPU, and make the performance of high performance computing to balance in computing and communication. For developing high performance interconnection components of HPC, the research on InfiniBand specification began in 2000, and the InfiniBand network products branded with “SunWay” were worked out in 2003. Discussed in this paper are the components, archtecture and applications of the high performance computing system based on the InfiniBand technology, and then the result of performance test is shown.
