Abstract


Accompanied by the rapid development of computer technology and the wide application of Internet technology in today's society , more and more computing technology based on up to achieve network platform . Currently the Internet , computer resources into explosive growth . In order to meet the needs of large - scale computing power and mass data storage and processing , we rely on network computing to create a virtual computing environment that can support resource sharing and integration , which is an effective solution . In this paper, a large-scale high-performance computing needs , build virtual computing environment suitable for seismic data processing . The study was designed to improve the efficiency of the data processing , the full and efficient use of computing resources so that tasks transparent , convenient, and efficient , should be submitted , and allowed to fast matching and efficient implementation in optimal computing resources . Less contact between the separability data the natural seismic data data data . Relatively speaking, a data file is generally larger , so a single file processing node computing resources is very high , in order to take full advantage of the computing resources must be divided according to the task and resource attributes its research process . The accurate solving data by the optimization process is more difficult , this paper uses the improved particle swarm optimization (Particle Swarm Optimization, PSO) to divide the size of solving . Fast matching of resources and tasks completed divided by the introduction of the Analytic Hierarchy Process (Analytic Hierarchy Process, AHP) . After experimental verification , this program has a higher efficiency of the implementation .
