  Pulsar acceleration searches are methods for recovering signals from radio
telescopes, that may otherwise be lost due to the effect of orbital
acceleration in binary systems. The vast amount of data that will be produced
by next generation instruments such as the Square Kilometre Array (SKA)
necessitates real-time acceleration searches, which in turn requires the use of
HPC platforms. We present our implementation of the Fourier Domain Acceleration
Search (FDAS) algorithm on Graphics Processor Units (GPUs) in the context of
the SKA, as part of the Astro-Accelerate real-time data processing library,
currently under development at the Oxford e-Research Centre (OeRC), University
of Oxford.
