CMSoft brings an OpenCL accelerated SVM implementation that can be used for general-purpose classification. Support Vector Machine (SVM) is a statistical learning tool considered to be the state-of-the art classifier for many applications today, including medical research and text categorization. Source code is provided showing classification of the MNIST handwritten database.
Phoronix Test Suite Beta 3 adds another handful of Open Computing Language tests for Linux and Mac OS X. Eventually Windows will also be supported. The new test profiles include JuliaGPU, MandelGPU, SmallPT-GPU, and MandelbulbGPU as well an OpenCL test suite has also been added.
The 2010 GPU Technology Conference will run from September 20th - 23rd at the San Jose Convention Center. Pre-conference tutorials will include OpenCL optimization techniques and an introduction to OpenCL. The latest OpenGL features will discussed along with NVIDIA specific extensions. A fifty minute talk on WebGL will introduce this newly emerging standard and help you get started in WebGL development.
Recently, the really interesting discussions from a technological standpoint have been about the use cases for GPU computing. Tom Olson has had some fun recently in his OpenCL blog: where he tries to pick a fight with Jem Davies. Are they both right?
AMD has released an update to their ATI Stream SDK. This brings OpenCL 1.1 support to the table among many other enhancements. Although most of the improvements revolve around OpenCL, there is a host of additional hardware and OS support included also. The ATI Stream SDK v2.2 product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
Tom Olson, Director of Graphics Research at ARM, thinks he knows what the killer app for OpenCL is going to be. Have a seat, and pop over to Tom's blog to learn what the killer app for OpenCL will be. It may not be what you think.
The new release of the Voreen 2.5 volume rendering engine contains several new features. It is now possible to create and edit animations, which can be exported as videos. Furthermore, Voreen now contains a GPU-based multi-volume renderer, allows aggregation of subnetworks and supports iterative processing by exploiting loops in the network graph, and contains support for OpenCL used for some processors.
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.
Unified Color Technologies announced HDR Expose, an OpenCL GPU enhanced application providing photographers complete control of their HDR workflow. HDR Expose replaces HDR PhotoStudio allowing the creation of natural looking HDR images. Notable improvements include a re-designed UI, improved RAW image processing, digital RGB and Bch meter, simplified batch processing and halo reduction and local contrast tools.
Image2D variables play a very important role in OpenCL because they use the texture caching and samplers of the GPU and thus are very suitable to store large arrays and/or data that has to be accessed very often. CMSoft Image2D tutorial covers how to manipulate Image2Ds and how to reinterpret a vector as a Image2D variable, with useful C99 source code to retrieve vector data from a Image2D.
