Abstract
A typical array processing problem is run on parallel computers. A critical issue in using parallel computers is to maintain the speed up with respect to the increased number of processors. A VHDL simulation model was developed to predict the speed up of the parallel computer system. It is important to characterize the computation and communication work loads in the partition procedure. Ethernet prediction results are compared with running data. The accuracy of this model is satisfactory. The prediction of the speedup of a frequency domain beamformer is in progress.<>
