Embodiment Construction

[0014] The specific implementation methods are analyzed for two switching network topologies commonly used in commercial use. Two types of switching networks are centralized switching networks and distributed switching networks.

[0015] figure 2 Shown is a 12-port reconfigurable interconnection network. The reconfigurable network topology is a centralized switching network and a distributed switching network, which correspond to FPGA configuration files, centralized switching network configuration files, and distributed switching network configuration files, respectively. By loading the configuration files in the configuration chip, different topology interconnection networks are realized.

[0016] image 3 and Figure 4 Shown is a centralized switching network, Figure 5 and Image 6 It is a distributed switching network.

Description

technical field [0001] The patent of the present invention relates to the realization of the reconfigurable interconnection network in the computer field. Background technique [0002] In the computer field, the network is to use physical links to connect individual workstations or hosts together to form data links, so as to achieve the purpose of resource sharing and communication. At present, high-speed interconnection networks are widely used in the interconnection between computing nodes or I / O nodes in high-performance computers. However, these high-speed interconnection networks are only designed for a specific network topology, and cannot meet the requirements of various applications for different network topologies. Contents of the invention [0003] In order to solve the problem that the high-speed interconnection network in a high-performance computer cannot meet the requirements of various applications for different network topologies, the present invention pro...
