3 SAN DIEGO SUPERCOMPUTER CENTER OpenTopography As an NSF data facility, OpenTopography (OT, provides community access to high-resolution Earth science- oriented, topography data, and related tools and resources. OT provides several spatial data access functions and geoprocessing applications packaged as Web services across multiple backend servers. OPAL toolkit (http://opal.nbcr.net)http://opal.nbcr.net OPAL is an open-source toolkit developed by the National Biomedical Computation Resource (NBCR) and the SDSC that enables users to wrap scientific applications running on cluster and Grid resources as Web services. All Web services are built and deployed by leveraging OPAL toolkit. 3

4 SAN DIEGO SUPERCOMPUTER CENTER Service Registry An SOA based pluggable service infrastructure has been prototyped to enable scientists to contribute processing tools and algorithms for operating on OT LIDAR datasets, for use by the larger community. Service registry is a key piece for enhancing and achieving reuse of services that allows service providers/consumers to organize information about services and allow facilities to publish their services. 4

5 SAN DIEGO SUPERCOMPUTER CENTER OGC WPS (Web Process Service) Services It defines a standardized interface that facilitates the publishing of geospatial processes, and the discovery of and binding to those processes by clients. TauDEM (Terrain Analysis Using Digital Elevation Models) services for the hydrology science Adapted as science driver and community service to connect OT and CyberGIS projects. TauDEM functions are wrapped as OGC WPS Web services. A single data access service which invokes a set of OT data and application services. WPS repository can be suitable for the service registry potentially and these service registry can be used for the service integration and composition. 5

6 SAN DIEGO SUPERCOMPUTER CENTER Gordon: Computing Facility Data-intensive applications that involve “very large data-sets or very large input-output requirements”. A “data-intensive” supercomputer based on SSD flash memory A system designed to accelerate access to massive data bases being generated in all fields of science, engineering, medicine, and social science. TauDEM services, including full OT software stack, has been deployed to a dedicated Gordon’s I/O node. 6
