Massively parallel computers, such as the Cray T3D, have historically supported resource sharing solely with space sharing. In that method, executing them on distinct processors solves multiple problems. This project developed a dynamic time- and space-sharing scheduler to achieve greater interactivity and throughput than could be achieved with space-sharing alone. CRI and LLNL worked together on the design, testing, and review aspects of this project. This project was a multi-partner CRADA with nine industrial partners. During this portion of the CRADA, Hughes Aircraft assisted in development and validation of an MPP physics code by providing data of generic microwave circuit performance. This data and technical guidance was used to test solutions to the time-dependent Maxwell field equations on the Cray T3D system. This CRADA was unilaterally terminated by LLNL before scheduled completion. During Phase One of this project, we constructed the enhancements necessary to tackle microwave design problems, to port and optimize the code on the T3D parallel computer, to do basic mesh generation and visualization. We also illustrated the utility of MPP versions of discrete surface integral DSI (time-domain) and integral frequency-domain methods. Work was stopped in Phase Two of the effort.
