摘要
虚拟化技术是提升已有计算机资源利用率的一种有效手段。尽管它已经在高性能计算系统中崭露出自己在提升物力资源利用率以及用户的安全性上的优势,但是却一直没有受到重视,文章利用各种基准以VMWare Server,Xen,and OpenVZ we这几种虚拟化产品在SMP性能、文件系统中的表现,对完全虚拟化、准虚拟化以及操作系统级虚拟化在HPC涉及到的各个方面进行评测。
Virtualization is a common strategy for improving the utilization of existing computing resources, particularly within data centers. However, its use for high performance computing （HPC） applications is currently limited despite its potential for both improving resource utilization and providing resource guarantees to its users. This paper evaluates various VMs by using various standard benchmarks. And by using VMWare Server, Xen, and OpenVZ, the suitability of full virtualization, paravirtualization and operating system-level virtualization in terms of SMP performance and file system performance is also examined.
