本文研究了物理计算服务器中虚拟机（VM）上运行的应用程序的性能下降，重点关注HPC应用程序。我们选择三个基准作为数据中心的预期工作负载：HPC应用程序，数据库应用程序和Web服务器应用程序。然后，我们把执行两个应用程序的虚拟机一起在一个物理计算服务器，并评估在每个应用程序的性能下降。我们还调查了每个应用程序的资源消耗和性能下降的原因。实验结果表明，在物理计算服务器上运行两个高性能计算应用程序的虚拟机之间的干扰会显著降低应用程序的性能。
This paper investigates the performance degradation in application programs running on virtual machines (VMs) in a physical computing server with a focus on HPC applications. We select three benchmarks as the expected workload in a data center: HPC applications, database applications, and web server applications. Then, we put VMs executing two application programs together in a physical computing server and evaluate the performance degradation in each application program. We also investigate the resource consumption in each application program and the reason for the performance degradation. The experimental results indicate that the interference among VMs executing two HPC application programs with high memory usage and high network I/O in the physical computing server significantly degrades the application performance.
