GPCBenchMarkOCL is a General Purpose Computing benchmark that evaluates the performance of OpenCL enabled devices with a collection of algorithms and applications. GPC benchmark can evaluate and report on the number and frequency of computing units, architecture, memory bandwidth, on-chip cache and memory and synchronize penalty.
Ever wonder what the difference between CUDA and OpenCL is? Streamcomputing has done a good job in clarifying the differences between CUDA and OpenCL. The article covers speed, language, heterogenous vs. homogenous and some of the terminology.
NVIDIA is looking for submissions from industry and academia. The submission should be about your work using the GPU for computing or graphics, and can be completed or currently in progress. The deadline is June 1st 2010. Complete details can be found on the NVIDIA website.
NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:
- ARB_texture_compression_bptc – provides new texture compression formats for both fixed-point and high dynamic range floating-point texels.
- EXT_shader_image_load_store - allows GLSL- and assembly-based shaders to load from, store to, and perform atomic read-modify-write operations to texture images.
- EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
- NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
- NV_gpu_program5 - provides assembly programmability support for new hardware features provided by NVIDIA’s OpenGL 4.0-capable hardware in vertex, fragment, and geometry programs.
- NV_tesssellation_program5 - provides assembly programmability support for tessellation control and evaluation programs.
- NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5 and GLSL 4.00. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector integer data types, and more. Additionally, it allows patches (as used in tessellation) to be passed on to the geometry shader, used as input to transform feedback, and rasterized as a set of control points.
- NV_shader_buffer_store – extends the bindless graphics capabilities of the NV_shader_buffer_load extension. This extension provides the ability to store to buffer object memory, and to perform atomic read-modify-write operations, using either GLSL- or assembly-based shaders.
The official feedback thread is available in the OpenGL Discussion Forums. The drivers and extension documentation can be downloaded from http://developer.nvidia.com/object/opengl_driver.html
Khronos has released the OpenCL 1.0 man page XML sources. The XML source has been released under the Khronos Free Use License (BSD-like) so people can modify, repackage, redistribute etc.
Lab3D is a 3D Laboratory project that uses OpenCL and OpenGL to display and manipulate 3D models created from regular 3D files and mathematical equations. Some of Lab3D features are OBJ and DXF (AutoCAD) models loading, dynamic and static 3D models creation, stereoscopic visualization and WiiMote interaction. Buffer objects are used to accelerate animations in systems that support it.
The Khronos developer library has been updated with a new Khronos Group Overview, and new photos from recent Khronos events. The Developer Library contains Khronos lecture series presentations, whitepapers, and supporting materials and is updated on a regular basis.
MainConcept GmbH has announced a strategic collaboration with AMD to accelerate digital video encode. MainConcept plans to leverage ATI Stream technology from AMD and OpenCL™ standards to accelerate the encoding capabilities within its H.264/AVC (Advanced Video Coding) Pro Encoder codec package by taking advantage of available graphics processors (GPUs) in PCs. MainConcept will be demonstrating this encode acceleration for the first time on AMD's latest professional graphics solution, the ATI FirePro(TM) V8800, at the 2010 NAB Show April 12-15 in Las Vegas, Nevada. MainConcept is a wholly-owned subsidiary of DivX, Inc. (Nasdaq: DIVX) and one of the world's premier providers of video and audio codecs and software development kits (SDKs) to the consumer, broadcast and professional markets
Fixstars Corporation announced the release of their OpenCL Programming Book which is available on Amazon Kindle, Apple iPad and Fixstars' website. More information on the OpenCL book is available on the Fixstars website.
Skew Matrix Software LLC is pleased to announce OpenSceneGraph v2.8.3, a new release of the leading cross-platform, open source, OpenGL-based scene graph SDK. The 2.8.3 release includes support for Mac OS X 10.6 (Snow Leopard), 3DS file export capability, integrated support for the FFmpeg project and Autodesk FBX technology, and many other new features and enhancements.
