چکیده
As a result of the demand for high performance graphics capabilities driven by the computer video game industry, the processing performance of video cards is rapidly evolving. Recent trends in computing have shifted toward multi-core processors and programmable graphics processors equipped with highly parallel data paths for processing geometry and pixels. Multi-core machines are now readily available with 2 cores, but machines with 4, 8, and even 16 or more cores are projected for the near future. Data parallelism in modern graphics cards is also increasing with raw performance of graphics processing units (GPUs) surpassing performance of central processing units (CPUs). While initially specialized for processing computer graphics, GPUs can be programmed for general-purpose computations. As a result, GPUs have become useful computational tools providing inexpensive highly parallel data paths to accelerate a wide range of scientific and simulation applications.
