Time-Lapse Seismic Parallel Forward Modeling with Xen Virtualization
Qicheng Liu, Weimin Zheng, Yibin Song · 2008
The wave equations based time-lapse seismic forward modeling algorithms and their parallel implementation based on virtualization technology is discussed in this paper. The modeling algorithms use an explicit finite difference scheme, which is high order accurate in space and time. A domain decomposition strategy is used for distributing the workload and the tasks communicate via MPI message passing calls. A virtualization framework using Xen for parallel forward modeling system of time-lapse seismic is considered and designed. The performance of time-lapse seismic parallel forward modeling applications may benefit from virtualization in several ways.
