摘要:

并行编程模型在分布式计算中发挥着很重要的作用，随着人们对高性能计算需求的不断扩大和各种新技术的出现，并行编程模型也处于不断的发展和完善之中。对两种主要的编程模型进行了详细的分析和研究，针对前两种模型的优缺点分析并研究了两级并行模型的使用范围和优势等，最后针对硬件的新发展提出了新的编程模型的发展TBB＋MPI。并在基于CMP的集群系统中实现了矩阵相乘的算法。实验结果显示TBB＋MPI在多核集群编程方面有明显的优势，因此模型TBB＋MPI更适合于多核集群。

Abstract:

Parallel-programming model takes a very important part in distributed computing. With the increasing need for high performance computing and the appearances of many new technologies,parallel-programming model is also in need of exploration and improvement. Two major parallel-programming models are compared in details in many aspects at first. Against to the advantages and disadvantages of the first two models, the usage and advantages of the two-level parallel is studied. According to the development of hardware, given the future trend of parallel-prograrmning model TBB＋MPI. And has realized the matrix multiplication algorithm based on the CMP cluster system. The experiment result showed that the new model got the performance improved
