Massively parallel hypercube FFTs CM-2 implementation and error analysis of a parallel trigonometric factor generation method.

Massively parallel hypercube FFTs [electronic resource] : CM-2 implementation and error analysis of a parallel trigonometric factor generation method.

On parallel computers, the way the data elements are mapped to the processors may have a large effect on the timing performance of a given algorithm. In our previous paper, we have examined a few mapping strategies for the ordered radix-2 DIF (decimation-in-frequency) Fast Fourier Transform. In part...
