A high-speed interconnection network topology discovery method, device, medium and high-performance computing system

Abstract

The invention discloses a high-speed interconnection network topology discovery method, device, medium and high-performance computing system, wherein the steps of the topology discovery method include starting from the network interface chip of the node to read peer label information and adding to the seed queue, aiming at The seed queue iteratively finds the peer tag information and records it in the adjacency table and constructs a source routing table entry pointing to the peer network interface chip. Finally, the actual topology expressed by the adjacency table is compared with the expected topology to find the wrong port connection. In addition, the present invention also discloses a device, a medium and a high-performance computing system corresponding to the foregoing method for discovering the topology of a high-speed interconnection network. The invention supports the rapid realization of network topology structure discovery and the comparison of the actual topology structure and the expected topology structure to find the wrong port connection relationship, thereby shortening the interconnection network debugging time and improving the interconnection network construction efficiency.

Description

technical field [0001] The invention mainly relates to the high-speed interconnection network field of high-performance computing systems, and in particular relates to a method, device, medium and high-performance computing system for finding a topology of a high-speed interconnection network. Background technique [0002] The life cycle of a high-performance computing system is mainly composed of three parts: first, the construction time of the computing system, including the hardware and software installation, configuration, debugging, testing and other processes of each subsystem; second, the normal operation time of the computing system, that is, the computing system can The time to provide services for high-performance computing applications; the third is the system fault handling time. Some minor system faults can be diagnosed and handled online, while individual serious faults require post-processing or even shutdown maintenance after the application is offline. As th...
