摘　　要：多物理耦合是一类普遍的复杂应用问题。并行计算时,在充分考虑各个物理过程的基础上,还需要在不同物理过程之间建立数据依赖关系并交换物理量值。这无论对并行算法设计,还是对并行编程实现来说,均具有较大的难度。JASMIN框架提供联邦计算功能,很好地封装和实现了单层结构网格上的多物理耦合并行计算。该功能实际应用于激光聚变和地球系统模式等领域,支撑研发了多个应用程序,可以有效使用成千上万个处理器核进行数值模拟。Multi-physics simulation is a type of complex applications. When computing in parallel, one has to consider not only the implementation of different physical processes, but also the construction of data dependencies and exchange of physical quantities in different physical processes. This is challeng- ing in both design and implementation of parallel algorithms. JASMIN provides federation parallel com- puting, which encapsulates and implements multi-physics parallel computing on single level structured grids. We apply this feature in real word scenarios such as ICF and earth system simulations and develop several applications. These applications can then run numerical simulations with thousands of CPU cores.
