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.
