XVM虚拟环境下并行程序的性能评测

Performance Evaluation of Parallel Program in Xvm Virtual Environment

该文引入speedup作为并行程序的性能评测指标,分析了并行程序在不同类型和不同数量的客户虚拟机中运行的性能差异,实验表明,MPI并行程序在xVM虚拟化环境中的运行性能接近非虚拟化本地主机的性能,在半虚拟化环境中的并行程序性能超过全虚拟化环境中的并行程序性能。

This paper introduce speedup as the basic performance metric.The performance characteristics of parallel program on different types and number of guest VMes was investigated.The results show that the performance of traditional MPI parallel programs in xVM virtual environment is close to it in native,non-virtualized environment and the performance of parallel programs in para-virtualized environ-ment exceeds that of parallel programs in full-virtualized environment.
