Abstract
Containerization, or OS-level virtualization has taken root within the computing industry. However, container utilization and its impact on performance and functionality within High Performance Computing (HPC) is still relatively undefined. This paper investigates the use of containers with advanced supercomputing and HPC system software. With this, we define a model for parallel MPI application DevOps and deployment using containers to enhance development effort and provide container portability from laptop to clouds or supercomputers. In this endeavor, we extend the use of Sin- gularity containers to a Cray XC-series supercomputer. We use the HPCG and IMB benchmarks to investigate potential points of overhead and scalability with containers on a Cray XC30 testbed system. Furthermore, we also deploy the same containers with Docker on Amazon's Elastic Compute Cloud (EC2), and compare against our Cray supercomputer testbed. Our results indicate that Singularity containers operate at native performance when dynamically linking Cray's MPI libraries on a Cray supercomputer testbed, and that while Amazon EC2 may be useful for initial DevOps and testing, scaling HPC applications better fits supercomputing resources like a Cray.
