platforms

A collection of tools for comparing and evaluating Earth System Models on new computer platforms.

The following is a plot of the "speed" v "number of compute cores" (i.e., a scaling curve" for a simple MOM6 Ocean model that can be cloned/built/run using this repo.

The following is a plot for time to solution of a benchmark test that shows the utility of using a GPU in numerical calculations. It shows that as the problem size increases the GPU outperforms the CPU, particularly when using "managed memory" mode of the NVIDIA compiler via -ta=nvidia:managed.
