摘要/Abstract

摘要： 多核处理器的新特性使多核机群的存储层次更加复杂，同时也给MPI程序带来了新的优化空间。国内外学者提出了许多多核机群下MPI程序的优化方法和技术。测试了3个不同多核机群的通信性能，并分别在Intel与 AMD多核机群下实验评估了几种具有普遍意义的优化技术:混合MPI/OpcnMP、优化MPI运行时参数以及优化 MPI进程摆放，同时对实验结果和优化性能进行了分析。

关键词: 多核机群，存储层次化，MPI程序优化，混合MPI/OpcnMP, MPI运行时参数，MPI进程摆放

Abstract: The new features of multi-core make the memory hierarchy of multi-core clusters more complex, and also add the optimization space for MPI programs. We tested the communication performance of three different multi-core clus- ters, and evaluated some general optimization technologies, such as hybrid MPI/OpenMP, tuning MPI runtime parame- ters and optimization of MPI process placement in Intel and AMD multi core cluster. I}he experiments result and opti- mization performances were also analyzed.

Key words: Multi-core cluster, Memory hierarchy, MPI programs optimization, Hybrid MPI/OpenMP, MPI runtime parameters, MPI process placement
