TL;DR: OpenCL in Action begins by presenting the core concepts behind OpenCL, including vector computing, parallel programming, and multi-threaded operations, and then guides you step-by-step from simple data structures to complex functions.
Abstract: OpenCL in Action is a thorough, hands-on presentation of OpenCL, with an eye toward showing developers how to build high-performance applications of their own. It begins by presenting the core concepts behind OpenCL, including vector computing, parallel programming, and multi-threaded operations, and then guides you step-by-step from simple data structures to complex functions. ABOUT THE TECHNOLOGY: Whatever system you have, it probably has more raw processing power than you’re using. OpenCL is a high-performance programming language that maximizes computational power by executing on CPUs, graphics processors, and other number-crunching devices. It’s perfect for speed-sensitive tasks like vector computing, matrix operations, and graphics acceleration. ABOUT THIS BOOK: OpenCL in Action blends the theory of parallel computing with the practical reality of building high-performance applications using OpenCL. It first guides you through the fundamental data structures in an intuitive manner. Then, it explains techniques for high-speed sorting, image processing, matrix operations, and fast Fourier transform. The book concludes with a deep look at the all-important subject of graphics acceleration. Numerous challenging examples give you different ways to experiment with working code. A background in C or C++ is helpful, but no prior exposure to OpenCL is needed. WHAT’S INSIDE: Learn OpenCL step by step; Tons of annotated code; Tested algorithms for maximum performance.

TL;DR: This work investigates topology optimization based on the solid isotropic material with penalization approach on compute unified device architecture enabled graphics cards in three dimensions and finds the GPU code to be extremely efficient, being faster than a 48 core shared memory CPU system.
Abstract: We investigate topology optimization based on the solid isotropic material with penalization approach on compute unified device architecture enabled graphics cards in three dimensions. Linear elasticity is solved entirely on the GPU by a matrix-free conjugate gradient method using finite elements. Due to the unique requirements of the single instruction, multiple data stream processors, special attention is given to the procedural generation of matrix–vector products entirely on the graphics card. The GPU code is found to be extremely efficient, being faster than a 48 core shared memory CPU system. CPU and GPU implementations show different performance bottlenecks.

TL;DR: In this article, a system and method for communication in an online electronic chat environment having multiple communication devices connected to each other in a communication network is provided, which allows for the mixing of chat and graphics in a common window when material is moved between the two modalities.
Abstract: A system and method for communication in an online electronic chat environment having multiple communication devices connected to each other in a communication network is provided. Displayed on a display screen of an electronic communication device of the multiple communication devices, is a chat region configured to hold text, and a graphics region to hold graphic objects. The chat region and the graphics region are positioned on a common electronic canvas of the display screen. Text from the chat region can be moved to the graphics region, and graphic objects in the graphics region may be moved to the chat region. The design allows for the mixing of chat and graphics in a common window when material is moved between the two modalities. In additional embodiments, the text in the chat region and the graphics in the graphics region are synchronized whereby movement of one causes action in the other.

TL;DR: In this article, an adaptive hierarchical visibility (AHV) method performs occlusion-culling in a tiled 3D graphics hardware architecture, where polygon bins for each tile are bucket-sorted in order of increasing depth Z. After some number of bins are rendered, a single layer, hierarchical Z-buffer (HZ) may be constructed from the Z buffer thus far accumulated for the rendered bins, if it would be cost effective to do so.
Abstract: A data processing system providing high performance three-dimensional graphics includes at least one system processor, chipset core logic, a graphics processor, and a Z-buffer. In one embodiment an adaptive hierarchical visibility (AHV) method performs occlusion-culling in a tiled 3D graphics hardware architecture. Polygon bins for each tile are bucket-sorted in order of increasing depth Z. Polygon bins are rendered starting with the bin closest to the viewer. After some number of bins are rendered, a single layer, hierarchical Z-buffer (HZ) may be constructed from the Z-buffer thus far accumulated for the rendered bins, if it would be cost effective to do so. Subsequent bins are rendered by first testing their polygons against the HZ buffer to see if they are hidden. Also described are an integrated circuit for implementing the AHV algorithm, and a computer-readable medium storing a data structure for implementing the AHV method and apparatus.

TL;DR: This work compared the perceptual structure of visual line graphs depicting simulated time series data with that of auditory displays (musical graphs) presenting the same data, showing that important data characteristics were perceptually salient in either presentation mode.
Abstract: By applying multidimensional scaling procedures and other quantitative analyses to perceptual dissimilarity judgments, we compared the perceptual structure of visual line graphs depicting simulated time series data with that of auditory displays (musical graphs) presenting the same data. Highly similar and meaningful perceptual structures were demonstrated for both auditory and visual modalities, showing that important data characteristics (function slope, shape, and level) were perceptually salient in either presentation mode. Auditory graphics may be a highly useful alternative to traditional visual graphics for a variety of data presentation applications.
