Developing Parallel Active Tectonics Simulations Using GeoFEST and the PYRAMID Adaptive Mesh Refinement Library

The Geophysical Finite Element Simulation Tool (GeoFEST) can be used to simulate and produce synthetic observable time-dependent surface deformations over both short and long time scales. Such simulations aid in interpretation of GPS, InSar and other geodetic techniques that will require detailed analysis as increasingly large data volumes from NASA remote sensing programs are developed and deployed. The NASA Earth Science Technology Office Computational Technologies Program (ESTO/CT) has funded extensions to GeoFEST to support larger-scale simulations, adaptive methods, and scalability across a variety of parallel computing systems. The software and hardware technologies applied to make this transition, as well as additional near-term development plans for GeoFEST, will be described.
