TRANSPUTER SUPERNODE SYSTEM FOR THE STUDY OF WAVE SCATTERING

A transputer supernode system is designed for studying wave scattering in parallel. The processor farm system is enhanced by converting each worker into a supernode comprising a transputer plus two networks of single-processor-boards. Softwares are written to handle low-level tas ks for parallel processing. The wave equations are solved by the metho d of moments. The scatter is represented by a grid of 2n wires of equa l length. Due to the manifold symmetry, the matrix can be fast enumera ted. The matrix is also efficiently inverted by the matrix partition m ethod. An adaptive scheme is used to evenly distribute loading among a ll processors and minimize inter-processor communications. Significant computational speedup is observed.
