The computational of the fast Fourier transforms (FFTs) is the cornerstone of many supercomputer applications. These include not only the predictable digital signal processing, speech recognition, image processing, and petroleum seismic analysis, but also other less obvious applications, such as in computational fluid dynamics, medical technology, multiple precision arithmetic and computational number theory. The PARKBENCH suite includes one large 3-D FFT test kernel.

  1. 3-D FFT. The PARKBENCH 3-D FFT kernel is the 3-D FFT PDE benchmark from the NAS Parallel Benchmark suite. It performs the essence of many spectral codes and is a rigorous test of long-distance communication performance.
This kernel may be obtained in the current distribution from the netlib repository.
