Applying Container Technology to the NOAA-GFDL MSD FRE Workflow, Part 1
DescriptionThe Flexible Modeling System (FMS) Runtime Environment (FRE) handles post processing of the National Atmospheric and Oceanic Administration (NOAA) research climate models on a computing cluster called Post Processing and Analysis (PPAN). FRE is currently only used on PPAN, but NOAA wishes to provide a reproducible environment that can be used by collaborators and the climate research community running future models. A containerized version of the post processing workflow has been developed using Podman, Singularity, and Apptainer. Designed to reduce user input, the container can handle directory setup, experiment configuration, and experiment running with minimal human interaction. Input is mostly passed in the form of a YAML, in which experiment details are read. The container is being used solely on NOAA infrastructure, but will soon be tested on external systems as well as the cloud.
