Testing Docker Container Performance for HPC Applications

Docker vs KVMThis article presents actual benchmark research by Alexey Ermakov and Alexey Vasyukov. The main goal for this article is to compare performance penalties when using KVM virtualization and Docker containers for creating isolated environments for HPC applications. The article provides both data obtained using synthetic tests (High Performance Linpack) and real life applications (OpenFOAM). The article highlights the influence on performance of major infrastructure configuration options – CPU type presented to VM, networking connection type used. As one of the results the authors strongly recommended to run benchmarks on exact application you’re going to run when considering virtualization or containerization as an option for HPC. Another important result is that a real «non-synthetic» application like OpenFOAM is more than 2 times faster in Docker containers than the same application in KVM. Read the article HERE.
