备注

对目前主要的大数据技术进行探讨,并对大数据计算方法在测震数据中应用进行分析,设计了基于大数据技术的测震数据存储模型以及基于海量数据运行率管理的计算模型,编写了分别基于单机多线程和大数据环境的程序,并进行对比实验。结果 表明:采用基于大数据技术的分布式管理和计算架构,可以较好地解决海量测震数据的管理困难、共享服务和科研计算方面的性能瓶颈。

In order to solve the bottlenecks of management,service and the calculation with the growing mass seismic data,we research the main large data technology and analyze the application of large data calculation method in seismic data,design the storage model of seismic data based on large data technology and the calculation model based on mass data operation rate management,at last we make a comparison experiment between single machine multi-thread and large data environment. The results show that the big data technology of distributed management and computing architecture can solve the bottlenecks problem of the management,data service and scientific research of mass seismic data.
