Embodiment Construction

[0072] The present invention will be further described in detail below with reference to the examples and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0073] This example discloses each layer structure of large-scale interconnection network topology, such as figure 1 As shown, the three routing nodes in a super routing node are fully interconnected as the first layer structure; at this time, each routing node uses two ports to connect to two terminals, and the other two ports are respectively connected to the same super routing The other two routing nodes within the node. Such as figure 2 The macroscopic view of the second layer structure of the topology shown, each super routing node leads to two links to connect to the other two super routing nodes in the same cluster, and leads to a link to connect to a super routing node in another cluster, Where n=2 and q=5, then the set X={1,4}, X'={2,3}. A single super routing node c...

Abstract

The invention discloses an order-flexible low diameter large scale interconnection network topological structure and a routing method thereof, solving the problem that a current network topological structure can not overcome disadvantages and deficiencies of the present router technique. In the technical scheme, a whole topology is connected by nq super routing nodes in a Galaxy graph mode, wherein the nodes are divided into n clusters, and each cluster comprises q super routing nodes. Each super routing node comprises a connected routing nodes; each super routing node leads out ah links to connect with other super routing nodes; (n-1) links are in connection with super routing node of other clusters in the Galaxy graph; (q-delta)/2 links are in connection with other super routing node of a same cluster; each routing node is in connection with p terminals, and leads out (a-1) links to connect with other (a-1) routing nodes in a same super routing node; h links are in connection with other super routing nodes. Compared with a current network topological structure, the network topological structure of the invention has the advantages of low network diameter and flexible configuration, and can effectively support an HPC system.

Description

technical field [0001] The invention relates to an interconnection network in the communication field, in particular to a low-diameter topological structure with flexible order and a routing method for a large-scale interconnection network. Background technique [0002] At present, the scale of large-scale computing systems has exceeded tens of thousands of nodes, such as my country's Tianhe-2 supercomputer system and IBM's Blue Gene (BlueGene / Q) system. These large-scale computing systems have strict requirements and demands on the overall performance, construction cost and power consumption of the system. The interconnection network is an important part of a large-scale computing system, and plays an important role in accomplishing the design goals of the entire system. End-to-end network latency, network bandwidth, and cost and power overhead are all important metrics used to evaluate interconnect networks. Designing network topology is very important for constructing i...
