| Abstract | Lightweight container virtualization has gained widespread adoption in recent years after updates to namespace and cgroups features in the Linux kernel. At the same time the Industrial High Performance community suffers from expensive licensing costs that could be managed with virtualization. To demonstrate that Docker could be used for suspending distributed containers with parallel processes, experiments were designed to find out if the experimental checkpoint feature is ready for this community. We run the well-known NAS Parallel Benchmark (NPB) inside containers spread over two systems under test to prove this concept. Then, pausing containers and unpausing them in different sequence orders we were able resume the benchmark. After that, we further demonstrate that if you carefully consider the order in which you Checkpoint/Restore containers, then the checkpoint feature is also able to resume the benchmark successfully. Finally, the concept of restoring distributed containers, running the benchmark, on a different system from where it started was proven to be working with a high success rate. Our tests demonstrate the performance, possibilities and flexibilities of Dockers future in the industrial HPC community. This might very well tip the community over to running their simulations and virtual engineering-applications inside containers instead of running them on native hardware. |
