Charliecloud ~ Unprivileged Containers for User-Defined Software Stacks

In this video from the 2018 Swiss HPC Conference, Michael Jennings from LANL presents: Charliecloud ~ Unprivileged Containers for User-Defined Software Stacks. "Today's software landscape in HPC is vast and varied. The challenges of maintaining supporting software stacks of combinatorial complexity -- M compilers times N MPI implementations times O parallelizers times P optimizers times... -- are well known and well understood, but even the best solutions in the world today (e.g., Spack/EasyBuild, Lmod) cannot induce consensus among all the scientists we serve. But what if I told you there was a way to allow your customers and colleagues to run their HPC jobs inside the Docker containers they're already creating? or an easily learned, easily employed method for consistently reproducing a particular application environment across numerous Linux distributions and platforms? There is. In this talk/tutorial session, we'll explore the problem domain and all the previous solutions, and then we'll discuss and demo Charliecloud, a simple, streamlined container runtime that fills the gap between Docker and HPC -- without requiring HPC Admins to lift a finger!"
