Description
Summary:An algorithm based on the moment method for wave scattering analysis is decomposed for parallel computation in a customer designed computer network. The network comprises of transputers and 80486 single processor boards. It is configured in a modified processor farm architecture. Softwares are written for handling low level tasks and special techniques are developed to alleviate the bottleneck imposed by RS422 communication differential links. As reduction of communication between various processing units is one of the key objectives, nearly all computational power of each processing unit in the system is expended in solving the wave scattering problem instead of communication and synchronization. Satisfactory computational speedup is observed. The system is not restrictive to algorithms used in wave scattering or antenna analysis; it is applicable to a class of algorithms which is relatively short yet extremely time consuming.< >
