面向地震数据处理的并行与分布式编程框架
Keywords: 地震数据处理,并行编程,分布式编程,编程框架,粗粒度数据并行
Abstract:
？本文提出了一个适用于地震资料处理的并行与分布式编程框架geopf。该框架构建在集群系统之上,采用粗粒度数据并行执行模型,它可以调度串行语言编写的处理模块,同时运行在多个计算节点或者单个节点内的多个cpu核上,隐藏了计算节点及其cpu核的调度、通讯与节点故障恢复、模块之间的数据传输等并行编程细节。经过实验评估,geopf框架从串行到并行的线性加速性能有所提高,处理相同任务的时间从21h33min缩减到15min27s,效果显著。geopf与商用的地震数据处理系统相比,在业务流程方面有一些相同特点,其不同之处就是geopf的处理模块具有自动并行特点,而大部分地震处理模块只能是串行方式。
