Abstract:

The container technology has been paid much attention as an virtualization tool in recent years, which can isolate resources and system environments. Containers help supercomputing applications to package dependencies into a lightweight and portable environment, and improve the effectiveness of application deployment. Containers have performance overhead in the process of virtualizing. In order to understand the performance characteristics of container virtualization on heterogeneous supercomputing platforms of CPU-GPU on IB network, standard benchmarks are used to conduct a comprehensive performance evaluation, including I/O, parallel communication and GPU computing. The evaluation results show that, as for I/O and GPU, the container has tiny overhead. The parallel communication overhead of the container increases with the increase of network load. An optimization method is proposed to give best performance of the container, which provides a basis for users to design applications and perform system configuration.
