Abstract

The invention provides a method of large scale cluster network cabling, relating to the separate cabling of three networks, namely a computing network, a management network and an ipmi (Intelligent Platform Management Interface) network. The specific cabling process comprises the following steps of planning cluster equipment, namely formulating a computing network topology in the combination of computing equipment; formulating a respective topology framework of the management network and the ipmi network; formulating a cabinet topology; fourthly, calculating the quantity of cables; performing the network cabling; and performing a cluster network performance test by using a testing tool. In comparison with the prior art, the method of the large scale cluster network cabling not only enables the correspondence between various demands and the various networks to be guaranteed, but also enables the network safety and stability to be guaranteed through the independent networks; meanwhile, the generation of network storm is prevented; and therefore, the actual demands of high performance computing clients are met.

Description

technical field [0001] The invention relates to network design and deployment of large-scale clusters, in particular to a large-scale cluster network wiring method. Background technique [0002] High-performance computing (HPC) usually uses computing nodes to run parallel computing software in a high-speed Internet network using parallel computing environments such as MPI to accelerate the efficiency of scientific operations. With the demand for high-performance computing capabilities, large-scale clusters are increasingly being used in universities and research institutes. The design of network cabling for large-scale clusters is an extremely important task for realizing network redundancy, improving network bandwidth, and reducing network delay. [0003] Most HPC computing clusters have less than 100 nodes, and the number of cabinets is kept within 4 cabinets at most. The network topology and cabinet topology are relatively intuitive, and the complexity is low. Network de...
