摘　　要：基于网格建立地震数据挖掘平台,充分利用网格中现有的资源和研究成果,可以减少系统开发、升级及维护的费用,提高系统可伸缩性;同时还能有效地提高对大量数据信息的处理能力,从而提高数据挖掘的速度.该文介绍了一个基于网格构建的地震数据挖掘平台,着重论述了其中的作业调度策略,并针对作业调度中面临的各种问题,设计并实现了一个能适应资源动态变化的JRA作业调度算法.A grid based earthquake data mining platform, which can not only make good use of existing resources within the grid and available research findings, but also reduce cost of development, upgrade and maintenance, and improve the system scalability. In addition, the platform enhances capability of processing large quantity of data and improves the execution speed. A platform of earthquake data mining based on grid is introduced, and the job schedule method emphasized. With respect to various kinds of job schedule problems in the system, a JRA job schedule algorithm that can adapt dynamic change of resource is proposed and implemented.
