Embodiment Construction

[0045] The applicant noticed through in-depth research that the load change of nodes is a time series with a high degree of self-similarity, so he proposed a dynamic allocation method and device for cluster services, which cleverly uses time series to predict the load of nodes. Monitor the load of each node in the cluster, predict the future load of each node based on historical monitoring data and current monitoring data, and coordinate service distribution in a timely manner according to the prediction results, so as to achieve adaptive load balancing.

[0046] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] see figure 1 , which shows a cluster service dynamic configuration device according to an embodiment of the present invention, including a load monitoring module, a performance optimization rule engine, a cluster service management module, and a cluster information library, wherein:

Abstract

The invention discloses a method and a device for dynamically distributing cluster services. The method comprises the following steps of: monitoring the loading condition of each node in a cluster; predicting the future loading condition of each node according to the historical monitoring data and current monitoring data of each node; and developing a service distribution scheme for each node in the cluster according to the predicted future loading condition of each node and a preset service balancing strategy, and regulating service distribution for each node in the cluster according to the developed service distribution scheme. By monitoring the load of the nodes and pre-optimizing the service distribution according to the monitored load, the method can balance the load, enhance concurrent services and reduce the probability of down caused by the overload of the nodes.

Description

technical field [0001] The invention relates to the field of computer clusters, in particular to a method and device for dynamically allocating cluster services. Background technique [0002] The development of high-performance computing technology is accompanied by the development of computer technology, that is to say, since the birth of computer technology, people have been striving for computer systems with higher computing power. In the past few decades, it can be said that the era of continuous innovation of high-performance computer architecture and communication technology, including MPP (Massive Parallel Processing, massive parallel processing structure), SMP (Symmetric Multi-Processor, symmetric multi-processor structure) , clusters and other various architectures and network interconnection technologies. Especially in recent years, cluster technology has developed rapidly and has become one of the mainstream architectures for building supercomputer systems. In t...
