Query: A new set of efficient SMP-parallel 2D Fourier subroutines   Extensive set of tests on different platforms indicated that there is a
performance drop of current standard de facto software library for the Discrete
Fourier Transform (DFT) in case of large 2D array sizes (larger than
16384x16384). Parallel performance for Symmetric Multi Processor (SMP) systems
was seriously affected. The remedy for this problem was proposed and
implemented as a software library for 2D out of place complex to complex DFTs.
Proposed library was thoroughly tested on different available architectures and
hardware configurations and demonstrated significant (38-94%) performance boost
on vast majority of them. The new library together with the testing suite and
results of all tests is published as a project on GitHub.com platform under
free software license (GNU GPL v3). Comprehensive description of programming
interface as well as provided testing programs is given.
