Abstract
In this paper the emerging technology of Linux containers is examined and evaluated for use in the High Energy Physics (HEP) community. Key technologies required to enable containerisation will be discussed along with emerging technologies used to manage container images. An evaluation of the requirements for containers within HEP will be made and benchmarking will be carried out to asses performance over a range of HEP workflows. The use of containers will be placed in a broader context and recommendations on future work will be given.
Highlights
Cloud computing enables ubiquitous, convenient and on-demand access to a shared pool of configurable computing resources that can be rapidly provisioned with minimal management effort
It is observed for all tests that the HEPSPEC values for benchmark execution in the container platform were within 2% of native performance
For tests running in KVM the simulation workload suffered notable performance decreases of 13.4% (26.4%) for a single process and 24.7% (32.5%) for a fully loaded system on the Xeon (Avoton) based server compared to native performance
