Summary on Grant Application Form
The programme will implement the WPRAM model on three parallel processing platforms, aiming to preserve its theoretical performance properties, particularly scalability. The first implementation, in conjunction with Transtech Parallel Systems Ltd., will use a 16-processor INMOS T9000/C104 system. Practical techniques will be implemented to support a shared address space through randomised hashing, based on existing theoretical results. Software asynchronous combining techniques will be implemented to support scalable concurrent data access. Benchmarking suites and tuning methodologies will be developed to aid portability and performance.An application generator will be developed for non-linear optimisation problems with embedded spatial interaction models, targeted at the WPRAM. A parallel template will be developed for executing the spatial interaction model; templated for non-linear optimisation will be developed both sequentially (for calibration of the model) and in parallel (for bootstrapping the model, and for embedding it in large locational problems). From high level specifications of the optimisation problem and spatial interaction model, the application generator will generate parallel code to the final application, as well as for calibrating and bootstrapping the model. Demonstration programs will be developed for a range of large locational problems, in conjunction with GMAP Ltd.
