Abstract

The invention discloses a node preheating method based on positive feedback. The node preheating method comprises the following steps: step 1, collecting a resource occupation state cached by a nodes;step 2, allocating an initial weight to the nodes and distributing a request to the nodes according to the initial weight; step 3, collecting the resource occupation state change condition of the nodes, and calculating the new weight of the nodes according to the distribution request quantity and the resource occupation state change quantity of the nodes; step 4, adjusting the request distribution quantity of the nodes according to the new weights of the nodes; step 5, repeating the step 3 and the step 4 until the nodes are closed. The method has the advantages that the nodes are effectivelypreheated, the requests are distributed to the nodes on the basis of positive feedback according to the node processing capacity, node collapse is effectively avoided, and the processing capacity of awhole cluster for a large number of concurrent requests is improved.

Description

technical field

[0001] The invention belongs to the technical field of node preheating, and in particular relates to a node preheating method based on positive feedback. Background technique

[0002] In the context of the information age, more and more information is stored and disseminated in electronic form. While electronicization provides feasibility for more efficient and rapid processing of information, it also brings greater challenges to the information processing system. The computing power, stability, and processing capacity of a single computer can no longer meet the needs of computing centers, and the cluster system was born to meet these demanding requirements. The cluster distributes the computing and processing pressure of information on each node through algorithms and networks, so as to provide the outside world with processing power and stability much higher than that of a single node when the processing capacity of a single node is limited. High concurre...
