# Opendda: a Novel High-Performance Computational Framework for the Discrete Dipole Approximation

@article{Donald2009OpenddaAN, title={Opendda: a Novel High-Performance Computational Framework for the Discrete Dipole Approximation}, author={James Donald and Aaron Golden and S. Gerard Jennings}, journal={The International Journal of High Performance Computing Applications}, year={2009}, volume={23}, pages={42 - 61} }

This work presents a highly optimized computational framework 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 optimizations 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…
