Multiprocessor FFTs. (English) Zbl 0624.65146
Several vector component fast Fourier transforms (FFT) are developed for both shared and non-shared multiprocessors. The focus is mainly on the efficiency of the movement of data. First eight FFTs algorithms are reviewed and then they are used to develop two FFTs for vector multiprocessors with shared memory. In the case of the hypercube FFTs, the emphasis is on algorithms which minimize interprocessors communication.
