Comparative Analysis of a Containerized Compilation Process Versus Bare-Metal Compilation Runs
DescriptionThe National Oceanic and Atmospheric Administration (NOAA) strives to understand and predict changes in the environment through improving climate modeling. These models can be tested for reproducibility using tools in the Flexible Modeling System (FMS) Runtime Environment (FRE) framework. The FRE ecosystem provides a model compilation tool, FREMAKE, in which the process of checking out source code and compiling the model is automated, and FRERUN, which automates running the compiled model. In order to make NOAA models more accessible, easier to maintain, and easier to develop, a FRE rewrite is being constructed with the idea of portability, flexibility, and simplicity to support container builds and runs, as well as bare-metal runs. To ensure optimal performance of the FRE container, a comparative analysis was done for container versus bare-metal compilation runs. Here, we analyze how the container runtime set-up affects the total runtime performance of the model compilation process.
