Establishing TauDEM as a Science Gateway Service on XSEDE for Scalable Hydrological Terrain Analysis.
Presenters: Yan Liu, Ye Fan (NCSA)
Principal Investigator: David Tarboton (Utah State)
Finer resolutions on Digital Elevation Models (DEM) data have been shown to have significant impact on hydrologically important variables and improve the accuracy and reliability of terrain analysis using DEM. TauDEM is a parallel computing solution to watershed delineation and the extraction of hydrological information from high-resolution DEMs. The first part of the talk will introduce a multi-institutional effort that leverages expertise in multiple disciplines (i.e., hydrology, computational science, geographic information science, and geography) through XSEDE ECSS to scale TauDEM from local cluster to supercomputers on national cyberinfrastructure (e.g., XSEDE) through rigorous computational performance profiling and analysis. The second part of the talk will present the data and software integration and science gateway application development experience obtained in establishing TauDEM as a CyberGIS Gateway application.
