Containerisation of NEMO Employing Singularity (CoNES)

We have detailed a method to containerise the NEMO Ocean General Circulation Model in a Singularity Image Format (SIF) file. It provides a flexible approach for the user to run the application without prior knowledge of compiler software and machine architecture.  The code that runs in the container is immutable and therefore maintains strict reproducibility required for scientific study. Another benefit of this approach is that development/testing of an ocean model configuration can be conducted on a local cluster before being transferred and scaled up onto the ARCHER2 system without the need to re-compile the code base. The SIF file is likened to packaged solution which accelerates the setup process, allowing the focus to be on the science. It may also be published alongside the scientific research to allow peers to reproduce or build upon it. This publication is the ARCHER2-eCSE02-13 Technical Report for the Containerisation of NEMO Employing Singularity (CoNES) project.
