Abstract:
Programmable graphics processing units (GPUs) are commonly included as hardware components in new computer workstations, including those workstations used for scientific computing. The current generation of GPU is roughly equivalent in processing power to current CPUs (Central Processing Units), but that power is rarely used to its full capabilities in an average scientific workstation. Numerous advances have been made recently in applying the GPU to parallel matrix processing tasks, such as the Fast Fourier Transform (FFT) [Moreland and Angel 2003].
Our primary goal is to produce a reusable, portable framework [Thompson et al. 2002] for applying GPU-accelerated computation to scientific computing problems. Our secondary goal to apply GPU-accelerated computation to a specific scientific computing problem to serve as a model: automated structure fitting in protein crystallography, a process that normally takes several hours or even days to execute on a sequential CPU.
