Problems solved by technology

Although network topology also has a great impact on network performance, this is ignored in the LogP model, because the study found that networks containing thousands of nodes, whether hypercube, butterfly or fat tree topology, have an average performance difference Only 2 times, so ignoring the network topology does not affect the modeling of the entire network

Embodiment Construction

[0045] The structure of the whole network is as Figure 4 shown.

[0046] The modules on each node call the initialization function of the communication library respectively to generate a tree network. The nodes that make up the network can be divided into three categories according to their position in the network:

[0047] ■ Root node. At the top of this structure, the root node of the communication tree is globally unique and only communicates downward, on which the main control program (front end) of the upper tool runs;

[0048] ■Leaf nodes. Located at the leaves of the tree, they are all computing nodes in the parallel system, which only communicate upward, and the monitoring program (back end) of the upper tool is running on it;

[0049] ■ Intermediate nodes. Located among the management nodes and leaf nodes, as their relay nodes, they run special communication programs and transmit messages downward and upward at the same time.

[0050] It should be noted that al...

Abstract

The invention relates to a tree-shaped data transmission network structure for a large-scale computer clustering system, wherein a balanced or quasi-balanced tree-shaped communication network of the structure is formed from the computer nodes of the clustering system, the computer nodes forming the network comprise a unique root node, at least one intermediate node and at least one leaf node, and each layer of node is only communicated with the node directly connected with same. On the basis of the tree-shaped network structure, the communication bottleneck problem of the large-scale clustering system can be effectively solved, and the communication performance of a network monitoring tool is greatly improved.

Description

technical field [0001] The invention relates to a communication network for data transmission and a construction method thereof, in particular to a communication network and a construction method for data transmission of a large-scale computer cluster network. Background technique [0002] Traditional cluster network monitoring tools generally adopt a C / S architecture and a 1-to-n communication model. When the computing scale is below dozens of nodes, better performance can be obtained. When the computing scale is expanded to hundreds or even thousands, Such a communication model obviously cannot meet the performance requirements of network monitoring tool communication. The present invention aims to solve this problem. By studying the communication bottleneck of the traditional model and using the classic LogP model to analyze the parallel computing network, it proves the necessity and superiority of using the hierarchical communication mode based on the tree network, and d...
