摘　　要：本文描述了化学复合驱数值模拟程序UTCHEM在分布式内存多计算机并行系统SMP-CLUSTER上并行化的关键技术。化学复合驱并行模型采用单程序多数据(SPMD)程序模型,利用区域分解方法将整个求解区域分解为子区域,使得多个计算节点同时求解一个单一的模拟问题。各计算节点通过消息传递对重叠区域的共享数据进行通信,以协调各节点之间的计算。目前仅对压力方程组求解部分进行了并行化实现,测试结果显示了较好的并行效率。This paper presents the key technology of porting the UTCHEM chemical flood simulator from a serial environment to the SMP-CLUSTER nodal environment of distributed memory massively parallel computers. The parallel modal of chemical flood simulator is a single program multiple data （SPMP） simulation modal. And message passing communication has been used to couple the node computations. This allowed for execution of a single problem across all of the computing nodes. This version of parallel chemical flood simulator was implemented by parallelizing the function segment of solving the pressure equations. The investigation shows that the parallel version of the code speed up well.
