FFT Implementations on nCUBE Multiprocessor

Three parallel FFT algorithms have been implemented on an nCUBE multiprocessor a nd their performances have been analyzed. We have also developed a communicatio n and computation model for the nCUBE system based on measurements. This model is then used to predict the execution time and communication time for the three FFT algorithms. These predictions have been verified with the execution of thes e algorithms on the nCUBE system.
