Integrating Web service and grid enabling technologies to provide desktop access to high-performance cluster-based components for large-scale data services

At Sandia National Laboratories, a data services system is under development to provide web-based access to high-performance computing clusters. These clusters host a set of scalable post-processing applications for very large data manipulation and visualization of results generated by large-scale simulations in support of the design to analysis process for ensuring safety and reliability of the nation's nuclear weapons stockpile. The primary contribution of this work is the integration of standards-based web services technologies, grid-enabling software, and a component framework for parallel computing, resulting in a service-oriented architecture which provides end users the ability from their desktops to manage and understand simulation results for very large, complex problems.
