Parallel Genetic Programming on Graphics Processing Units
In program inference, the evaluation of how well a candidate solution solves a certain task is usually a computationally intensive procedure. Most of the time, the evaluation involves either submitting the program to a simulation process or testing its behavior on many input arguments; both situations may turn out to be very time-consuming. Things get worse when the optimization algorithm needs...
متن کاملAlgorithmic performance studies on graphics processing units
We report on our experience with integrating and using graphics processing units (GPUs) as fast parallel floatingpoint co-processors to accelerate two fundamental computational scientific kernels on the GPU: sparse direct factorization and nonlinear interior-point optimization. Since a full re-implementation of these complex kernels is typically not feasible, we identify the matrix-matrix multi...
متن کاملAutomatic Registration of Multispectral Images on Graphics Processing Units
The increasing programmability and parallelism of commodity graphics processing units (GPUs) makes them strong candidates for addressing some of the computational challenges faced by the remote sensing community. We have addressed one of those problems: the implementation of a fully automatic system for registration of remote sensing images. Our previous research in this field has focused on fe...
متن کاملAccelerating Genetic Programming through Graphics Processing Units
Graphics Processing Units (GPUs) are in the process of becoming a major source of computational power for numerical applications. Originally designed for application of time-consuming graphics operations, GPUs are stream processors that implement the SIMD paradigm. The true degree of parallelism of GPUs is often hidden from the user, making programming even more flexible and convenient. In this...
متن کاملImplementation of Image Processing Algorithms on the Graphics Processing Units
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...
