摘　　要：基于JASMIN框架,本文设计了多块结构网格拼接的并行算法并研制了相应的软件模块。该模块设计实现了网格块间关系统一描述算法,及网格片间统一通信调度策略,从而有效解决了多块结构网格拼接并行计算中的通信性能瓶颈问题。同时,该模块封装了数据分布存储、数据通信等并行计算细节,提供了规范接口,能够支撑用户简便地实现多块结构网格拼接并行计算。数值测试表明,该模块具有很好的并行性能,可以支撑应用程序扩展到上千核。A parallel module for the multiblock structured mesh computing has been designed and implemented in the JASMIN infrastructure. In this module,a blocks＇ relationship description algorithm and a unified communication schedule have been designed and adopted,which effectively solves the communication bottleneck broadly existing in multiblock structured mesh parallel computing. Meanwhile,by encapsulating parallel computing strategies, such as distributed storage, data communications, etc. , and providing standard interfaces, this module can help the user conveniently realize multiblock structured mesh parallel computing. According to our test results,applications based on this module can be run efficiently on thousands of processors, which proves the module＇s satisfying parallel computing performance.
