Texture and buffer access performance in OpenGL

Currently there are several ways to feed data to the GPU no matter of what API we use and what type of application we develop. In case of OpenGL we have uniform buffers, texture buffers, texture images, etc. The same is true for OpenCL and other compute APIs that even provide more fine-grained memory management taking advantage of the local data store (LDS) available on today’s hardware. In this article I’ll present the memory access performance characteristics of AMD’s Evergreen-class GPUs focusing on what this all means from OpenGL point of view. While most of the data is about the HD5870, the general principles and relative performance characteristics are valid for other GPUs, including ones from other vendors.

NVIDIA releases Fermi-Class Quadro OpenCL 1.1 and OpenGL 4.1 capable

The new NVIDIA Quadro Plex 7000 array, and Quadro 6000, Quadro 5000 and Quadro 4000 GPUs feature the new NVIDIA(R) Scalable Geometry Engines and leverage NVIDIA Application Acceleration Engines (AXE) to enable the world's fastest performance across a broad range of CAD, DCC and visualization applications. Rated at 1.3 billion triangles per second in raw performance, the Quadro 6000 enables users to interactively work with models and scenes that are five times more complex than ever before. All of the new GPUs are built on the latest industry standards such including OpenCL 1.1, OpenGL 4.1, DirectX 11 and DirectCompute. Jon Peddie has posted an indepth review of the new Quadro 5000.

Tech Soup announces open registration for its next OpenSceneGraph

Tech Soup announces open registration for its next OpenSceneGraph (OSG) course, October 5-7, 2010, in South Lake Union, Seattle, Washington. This class will teach students everything to be proficient in OSG in a 3-day intensive course. This course covers everything developers need to know to take maximum advantage of OpenSceneGraph from intermediate through advanced. We'll also take a tour through VirtualPlanetBuilder so you can build geospecific, tiled, paged datasets. Developers attending the course learn the mechanisms behind effective OSG development from scenegraph creation and manipulation through debugging & optimizing. Through instruction and labs, students build scenes and interact with real code from day one. The course is fast-paced, requires creativity and problem solving, and leaves users with a thorough immersion in OpenSceneGraph. Instruction is hands-on with numerous labs where students directly turn concepts into practical knowledge.
