Three-Dimensional Currents
This benchmark focuses on the S1 simulation as outlined in the paper "Modeled Three-Dimensional Currents and Eddies on an Alongshore-Variable Barred Beach", authored by Christine M. Baker, Melissa Moulton, Britt Raubenheimer, Steve Elgar, and Nirnimesh Kumar (2021). To better suit the purposes of this benchmark, we limited the simulation duration to 10 seconds to ensure that each simulation completes within approximately 20 minutes when running on the slowest machines.

Execution times comparison
Faster execution times are better. Units in seconds.Cost vs Time
The following plot shows how the execution times and costs vary with the number
of cores for each machine family.
AMD-based machines provide the best performance for the cost, with the c2d
and c3d families being the most cost-effective.
