Andrei Plamada from ETH Zurich gave this talk at the hpc-ch forum on Cloud and Containers. “Singularity is a container solution that promises to both integrate MPI applications seamlessly and run containers without privilege escalation. These benefits make Singularity a potentially good candidate for the scientific high-performance computing community. However, the performance overhead introduced by Singularity is unclear. In this work we will analyze the overhead and the user experience on both traditional HPC and cloud infrastructures.”
