Dynamic self-adapting graticule data migration method

Abstract

A dynamic self-adaptive grid data migration method is a dynamic self-adaptive mechanism when the grid data are required to migrate, which is mainly composed of a data migration controller, a target node selector, an index analyzer, a data migration operation kernel, and the like. When the data at a certain node in the grid cannot conform to the data service quality of the current user, or cause the network bandwidth waste, the data at the node are required to migrate at this time, by selecting factors such as the band-width the node reaches, the local management system property of the node, the data access load of the node and the size of the data to be migrated at present, and then preprocessing these factors, using the gene expression programming algorithm idea to dig out the functional relation between the target node and these factors, thereby the selection of the target node can be better executed by the functional relation obtained by digging.

Description

technical field [0001] The invention relates to a data migration method in grid computing, which is mainly used to solve the problem of grid data migration and belongs to the field of distributed computing software. Background technique [0002] Grid computing is a supporting platform for distributed and parallel computing, and it is a seamless, integrated computing and collaborative environment. It can use geographically dispersed computing resources as a virtual whole, such as high-speed interconnected heterogeneous computers, databases, scientific instruments, files, and supercomputing systems. The Internet-based grid computing system not only enables people to gather distributed computing power, form supercomputing capabilities, and solve problems in many major application fields such as high-energy physics, atmosphere, astronomy, bioinformatics, and petroleum geology (such as virtual nuclear explosions). , new drug development, weather forecast and environmental monito...
