Parallel Fast Fourier Transforms for Non Power of Two Data
This report deals with parallel algorithms for computing discrete Fourier transforms of real sequences of length N not equal to a power of two. The method described is an extension of existing power of two transforms to sequences with N a product of small primes. In particular, this implementation requires N = 2 p 3 q 5 r. The communication required is the same as for a transform of length N = ...
متن کاملP3DFFT: A Framework for Parallel Computations of Fourier Transforms in Three Dimensions
Fourier and related transforms are a family of algorithms widely employed in diverse areas of computational science, notoriously difficult to scale on high-performance parallel computers with a large number of processing elements (cores). This paper introduces a popular software package called P3DFFT which implements fast Fourier transforms (FFTs) in three dimensions in a highly efficient and s...
متن کاملQuantification of collagen organization using fractal dimensions and Fourier transforms.
Collagen fibers and fibrils that comprise tendons and ligaments are disrupted or damaged during injury. Fibrillogenesis during healing produces a matrix that is initially quite disorganized, but remodels over time to resemble, but not replicate, the original roughly parallel microstructure. Quantification of these changes is traditionally a laborious and subjective task. In this work we applied...

Let G(z) be a real entire function of order less than 2 with only real zeros. Then we classify certain distribution functions F such that the Fourier transform H(z) = R∞ −∞G(it)e izt dF (t) has only real zeros.
