Computation Oriented Parallel FFT Algorithms on Distributed Computer
Pengzhen Li, Weiqing Dong · 2010
FFT is a widely used algorithm, of which parallelization is a very important topic. There were a lot of works for this field and many parallel algorithms were published in several decades. In this paper, an algorithm named Computation Oriented Parallel FFT (COPF) is proposed. COPF which dates from the classic parallel radix-2 FFT focuses on the butterfly structure in FFT and adopts a proper strategy in parallel phrase on distributed system. In the serial phrase, COPF takes FFTW3 to accelerate the serial process and extends the application.
