地震资料处理环境中数据写策略研究

Research on Data Writing Strategy in Seismic Data Processing Environment

在地震资料处理环境中,用户频繁地大规模地震数据写操作后,针对文件系统池中存在地震数据写与分布不均衡的缺陷,剖析地震资料处理流程,探讨分析各种常规地震数据写策略,提出了一种基于概率的地震数据写策略,以满足文件系统池在不同初始状态下地震数据写均衡与优化分布.实验结果验证了其优越性.

In seismic data processing environment, the seismic data writing has imbalance without seismic data distribution optimization in the file system pool when large scale seismic data frequently perform writing and deleting operations. This study analyzes the seismic data processing classification and various conventional writing strategies of seismic data. It proposes a seismic data writing strategy based on the idea of probability which meets the optimization distribution of seismic data writing under different initial files in system pool. The experimental results show that the method is effective.
