ShellSet v1.1.0 – Parallel Dynamic Neotectonic Modelling: A case study using Earth5-049

Jon Bryan May, Peter Bird, and Michele Matteo Cosimo Carafa

Abstract. We present a parallel combination of existing, well known, and robust software used in modelling the neotectonics of planetary lithosphere, which we call ShellSet. The added parallel framework allows multiple models to be run at the same time and with varied input parameters. Additionally, we have added a grid search option to automatically generate models within a given parameter space. ShellSet offers significant advantages over the original programs through its simplicity, efficiency, and speed. We demonstrate the speedup obtained by ShellSet's parallel framework by presenting timing information for a parallel grid search, varying the number of threads and models, on a typical computer. A possible use case for ShellSet is shown using two examples in which we improve upon an existing global model. Initially we improve the model using the same data before further improving the model through the addition of a new scoring data set.

Short summary
ShellSet is a combination of well known geoscience software. It features a simple user interface and is optimized through the addition of a grid search input option, to automatically find optimal models, and the running multiple models in parallel. Performance tests show that for each number of models tested there is a performance benefit to parallel running (within reasonable limits based on computing hardware). Two examples demonstrate a use case by improving an existing global model.
