Flow control method for high-performance computer photoelectric hybrid network

Abstract

The invention relates to the technical field of computer networks, and provides a flow control method for a high-performance computer photoelectric hybrid network, which is based on a fat tree networktopology structure in which a first layer and a third layer are electric routers and a second layer is an optical router, and comprises the following steps of setting an early warning value; when thedata volume in one receiving buffer area of the electric router reaches the early warning value, closing a receiving port corresponding to the receiving buffer area, and broadcasting to the whole network; setting a receiving value; when the data volume in one receiving buffer area of the electric router reaches the receiving value, opening a receiving port corresponding to the receiving buffer area, and broadcasting to the whole network; and when the receiving port is closed, selecting other receiving ports of the electric router to receive data. According to the invention, the data packet ofthe broadcast port opening / closing message uses the existing data link, so that the utilization rate of hardware resources is improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a flow control method for a high-performance computer-optical hybrid network. Background technique [0002] The computer interconnection network is a medium for exchanging data between computing nodes (which can be understood as any networked electronic device terminal). When parallel computing tasks run on thousands of computing nodes at the same time, data communication between nodes is frequently carried out through the interconnection network. At this time, the structure and communication method of the interconnection network determine the network throughput and communication delay, which in turn affects the execution efficiency of high-performance computing applications. [0003] Since the optical router can directly control the routing of optical signals, the process of "storage-forwarding" is reduced compared with traditional electrical routers, and data can be ...

Problems solved by technology

However, the data of the optical router is directly forwarded, does not have a data cache structure, and cannot exchange traffic information between adjacent electrical routers and optical routers
