摘　　要：分析了流场计算的特点 ,探讨了面向流场计算的 MPP系统互联网络的设计 ,指出了这类系统的拓扑结构应优选低维 MESH结构、互联网络应追求低阻塞率而非高速率 ;探讨了 CCOTS技术在面向流场计算的 MPP系统设计中的应用 ,指出了In the basis of analysis for the characteristics of flow field computation, a computerized fluid dynamics (CFD) oriented MPP (massive parallel processing) interconnection network was discussed. It is preferable to select low dimensional mesh structure as the topological structure of the system, and the interconnection network should emphasize low block ratio rather than high speed. The application of the CCOTS (commercial commodity off-the-shelf) technique to the design of the CFD-oriented MPP system was explored. The result in application to design of PAR2000 MPP system shows that the CCOTS can improve usability and reliability of the MPP system and shorten development cycle of the system.
