A PROCESSOR CONNECTING APPARATUS APPLIED THE SCHEME OF HIERACHICAL CROSSBAR SWITCH AT A PARALLEL COMPUTER SYSTEM

摘要

The present invention relates to a system structure that can flexibly increase the number of crossbar switches using hierarchical crossbar switches when interconnecting multiple computer systems and operating them in a cluster. The first process of classifying a predetermined number of node groups, and for each of the node groups classified in the above process, one crossbar switch corresponds to each node group, and processor nodes belonging to each node group are connected to the corresponding crossbar switches. A second step of classifying the second step; classifying the crossbar switches connected to the node group in the step into a predetermined number of switch groups; and two upper ranks of one switch group for each switch group classified in the step; Crossbars that correspond to crossbar switches and belong to each switch group And a fourth process of connecting the switches and a fifth process of connecting the upper crossbar switches connected to the respective switch groups in the process. It can be freely configured according to the system resource needs of the expansion or application field and usage of the system.
