Methodology Go to the next , previous , or main section.
In this section we describe and motivate the methodology of our benchmark. We hope to convince you that our program makes a fair and accurate measurement of the performance and accuracy of FFT software. The FFT performance benchmark is designed to model a situation in which you repeatedly perform transforms of a particular size. This seems to be the most common kind of use for FFT code, especially in cases where performance is important. Essentially, a given array is repeatedly FFTed and the elapsed time is measured.
