摘要

文章围绕运行在惠普集群Omega地震处理软件平台上的"常家围子西部大连片深层叠前偏移处理"重点项目,研究了Omega软件叠前时间偏移并行作业运行机制,改进了系统运行环境,提高了系统运行的稳定性,保障了西部大连片深层5158.73平方千米叠前偏移处理任务的顺利进行,提高了叠前时间偏移作业并行运行效率,使得惠普集群运行效能得到了整体发挥。
The article gives a detailed introduction to the key project - in-depth pre-stack migration in western part of Changjiaweizi region based on HP cluster Omega seismic data processing software. According to the article, the frequent down-times of the I/O servers undertaking the tasks of input and output of data have resulted in such problems as inefficient job operation and unstable job performance and so on. In light of the fact that the data processing tasks can not be fully fulfilled in western part of the region, the Institute researched the operation mechanism featuring Omega software-based re-stack migration parallel processing,improved the system operation environment, and enhanced the stability of system operation.
