The objectives of the project are to acquire the necessary equipment for parallel computing including hardware and sofware, to transfer the available knowledge, to develop the required experience and to spread the technology in the country. To accomplish these objectives, the project workplan includes several activities including the application of parallel processing to industrial sectors, like mining and electric power industry, solving optimisation problems and using image processing. Another important activity within this project is the dissemination of results, which will be carried out by courses in fundamentals of parallel computing for academics, graduate students and the professional industry staff, and by publications of the results of the research.
After acquisition, installation and setting of the parallel computer PowerXplorer and the Parmacs software, two seminars took place that were supervised by engineers from Parsytec and Pallas with the participation of professors, research staff and postgraduate students. A review of the state of the art on fundamentals and applications of parallel processing was also completed. The first application has already been finished. A separable optimisation algorithm was written to solve the economic dispatch of the electric generation problem. The results obtained using numeric and graphic tools, provided by Parmacs 6.0, showed that parallel processing is faster in a factor of 4 than sequential processing. In this case, PowerXplorer presented an efficiency of 60%. The parallel solution of the economic dispatch problem with environmental constraints has also been analysed. The parallel implementation of an optimal economic control strategy for a mineral concentration plant is under development.
Fundamentals on parallel computating have been taught in two courses of the Graduate Program of the School of Engineering at the Catholic University of Chile, "IEE 3633 Design of Automatic Control Systems" and "IEE 3692 Advances Topics on Automatic Control". The results obtained until now and the applications accomplished are resumed in two papers, both in spanish, to be presented at two international conferences that will take place in Latin America.
