Acknowledgements The Tianhe-2 project is a great team effort and benefits from the cooperation of many individuals at NUDT. We would like to thank the entire Tianhe-2 development, applications, and bench- marking teams, and all the people who have contributed to the system in a variety of ways.

摘　　要：In this paper, we present the Tianhe-2 interconnect network and message passing services. We describe the architecture of the router and network interface chips, and highlight a set of hardware and software features effectively supporting high performance communications, ranging over remote direct memory access, collective optimization, hardwareenable reliable end-to-end communication, user-level message passing services, etc. Measured hardware performance results are also presented.In this paper, we present the Tianhe-2 interconnect network and message passing services.
