The paper describes features of the multithreaded algorithms implementation on contemporary CPU and GPU. The features of access of a graphics processing unit (GPU) memory are reviewed. The bottlenecks have been identified, in which there is a loss of speed in image processing. Recommendations are made for optimization of algorithms for processing image of various size. Examples of implementatio...

The influence of multi-core central processing units and graphics processing units on several algebraic multigrid methods is investigated in this work. Different performance metrics traditionally employed for algebraic multigrid are reconsidered and reevaluated on these novel computing architectures. Our benchmark results show that with the use of graphics processing units for the solver phase,...

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 av...
