| 摘 要： | 针对开源编译器Open64存在MPI不能自动并行化的问题,对Open64中面向Cluster的MPI代码自动生成进行了研究。分析了MPI代码自动生成模块在Open64体系结构中的位置,提出了基于Open64的MPI代码自动生成算法,并对其进行了实验验证。实验结果表明：该算法不但能够有效降低MPI并行程序的通信开销,而且能够明显提高其加速比。

| Abstract: | The MPI automatic code generation for Cluster based on Open64 is studied in relation to the problem that the open source compiler Open64 has no MPI automatic parallelizing function.Firstly,the location of MPI code automatic generation in the Open64 compiler architecture is analyzed,and then an Open64-based automatic generation algorithm for MPI code is presented,finally the experiments of testing the NPB benchmarks is conducted.The experimental results show that the algorithm can reduce communication overhe... |
