Aristotle Cloud Federation: Container Runtimes Technical Report

A National Science Foundation-sponsored container runtimes investigation was conducted by the Aristotle Cloud Federation to better understand the challenges of selecting and using Docker, Singularity, and X-Containers. The main goal of this investigation was to identify the "pain points" experienced by users when selecting and using containers for scientific research and to share lessons learned. Application performance characteristics are included in this report as well as user experiences with Kubernetes and container orchestration on cloud and HPC platforms. Scientists, research computing practitioners, and educators may find value in this report when considering the use and/or deployment of containers or when preparing students to meet the unique challenges of using containers in scientific research.
