OpenDDA: Home page
OpenDDA is a highly optimised computational framework, written in the C language, for the Discrete Dipole Approximation, a numerical method for calculating the optical properties associated with a target of arbitrary geometry that is widely used in atmospheric, astrophysical and industrial simulations. Core optimisations include the bit-fielding of integer data and iterative methods that complement a new Discrete Fourier Transform (DFT) kernel, which efficiently calculates the matrix-vector products required by these iterative solution schemes. The new kernel performs the requisite 3D DFTs as ensembles of 1D transforms, and by doing so, is able to reduce the number of constituent 1D transforms by 60% and the memory by over 80%. The optimisations also facilitate the use of parallel techniques to further enhance the performance. Complete OpenMP-based shared-memory and MPI-based distributed-memory implementations have been created to take full advantage of the various architectures.

The Ultimate Chemistry
The aim of this is site is to present new or less known issues connected with computational chemistry (CC), rather than provide a guide. I hope that the site will develop along with me and become a valuable source of highly specialized knowledge in the future.
