ABSTRACT
TianHe-1A (TH-1A) system has been developed by the National University of Defense Technology (NUDT). TH-1A supercomputer system began to run large-scale test applications and programs in November 2010, and then opened online to general users to provide high performance computing services. TH-1A system consists of 7,168 compute nodes and 16 commercial service nodes. The interconnection network is a proprietary high-speed network, named TH-net, providing low latency and high bandwidth communication between all kinds of nodes in the TH-1A system. In TH-1A high-speed communication network, the Network Routing Chips (NRC) is used for packet switching and routing, and the Network Interface Chips (NIC) is used for interfacing compute nodes and service nodes into the interconnect network. The TH-1A storage system is a large-scale shared storage system equipped with different types of storage servers and disk arrays. The operating system of TH-1A supercomputer is Kylin Linux. Kylin Linux for the TH-1A supercomputer utilizes a coordinated heterogeneous architecture, running on each node.
