A Review of the PEPSE (Parallel Electromagnetic Problem Solving Environment) Project

摘要

This paper describes a project - PEPSE - which is currently under way, under the auspices of the ESPRIT initiative sponsored by the European Commission, to adapt a suite of world class electromagnetics problem solving software, to enable it to run on the industry's leading parallel high performance computers, and thus solve problems which are currently beyond industry's capabilities. The paper will proceed to briefly review the code capabilities and the techniques used. A discussion of the main issues which govern the design and construction of the parallel codes, together with an indication of the implications on prospective performance of the PEPSE system, will also be included in the paper. This will cover such areas as domain decomposition, processor mapping, load balancing and data structure. Due to restriction on space only the EMA3D parallel design strategy will be alluded to. The last section of the paper discusses benchmark tests and contains initial scaleability results.
