弹性流体动力润滑问题的数值解的计算只能通过使用多重网格和多级技术相结合的细网格。在本文中，我们展示了如何并行化的多重网格和多层次的多重集成这些问题可能会完成，并讨论所产生的代码的可扩展性。构造求解器的性能模型，并用于对所获得的结果进行分析。结果显示，具有良好的速度和良好的可扩展性的分布式存储器架构，并与模型一致。版权所有© 2006约翰威利父子有限公司。
The computation of numerical solutions to elastohydrodynamic lubrication problems is only possible on fine meshes by using a combination of multigrid and multilevel techniques. In this paper, we show how the parallelization of both multigrid and multilevel multi‐integration for these problems may be accomplished and discuss the scalability of the resulting code. A performance model of the solver is constructed and used to perform an analysis of the results obtained. Results are shown with good speed‐ups and excellent scalability for distributed memory architectures and in agreement with the model. Copyright © 2006 John Wiley & Sons, Ltd.
