摘要
基于消息传递接口搭建火灾动力学模拟模型并行处理系统,针对建筑火灾流场采用多区剖分,将多个子区分配给相应节点(处理器)进行计算。计算结果表明,随着节点数的增加,计算时间明显减少。搭建的并行计算平台是可行的,可以胜任大规模并行计算和工程应用。
FDS parallel computing program has been compiled based on MPI（Message Passing Interface）.Specific to the fluid field using multi-region dissected and each sub-segment would be allocated appropriate panel point to calculate.The calculation shows that with the increased amount of processor computing time has significantly reduced.The procedure and method that the text has established was feasible,and could further extend to large-scale parallel computing and engineering application.
