Optical interconnection network system and communication method in supercomputer

Abstract

The invention discloses an optical interconnection network system and communication method in a supercomputer. The system disclosed by the invention comprises global optical switches, array electric switches and electric routers, wherein every 8 electric routers are interconnected to form a cube-like calculation cluster, and c calculation clusters can form a supercomputing node; k supercomputing nodes, 8 array electric switches and one global optical switch form a supercomputing array; and M supercomputing arrays are fully interconnected to form a network system. According to the system disclosed by the invention, the communication among the global optical switches, the array electric switches and the electric routers can be achieved by adopting two switching mechanisms which are electric packet switching and optical circuit switching; and according to the optical interconnection network system and communication method disclosed by the invention, relatively high network extensibility can be achieved, the utilization rate of links can be increased, different switching mechanisms can be supported, and the congestion of the network can be reduced.
