| Abstract: |
Analysis of relativistic binary pulsars is currently the best means by which to test theories of gravity in strong gravitational fields. Four-dimensional Hough Transformations can detect sinusoids in noisy images. Hough Transformations can be applied to Dynamic Power Spectra to detect the sinusoidal shift in observed spin frequency from binary pulsars in approximately circular orbits. We present four alternative GPU implementations of a Hough Transformation algorithm, which we apply to synthesized Dynamic Power Spectra data to determine the GPU kernel that provides the best acceleration. |
