Back in May we shared that NVIDIA was readying its OpenCL Linux driver
and had submitted their OpenCL 1.0 NVIDIA drivers to the Khronos Group for certification. As of this morning, NVIDIA has now released its OpenCL driver for Linux (and Windows), but it's only available if you are a registered NVIDIA developer. Developers of hand-helds, games, workstations, and GPU computing are able to apply
and if you are lucky you will get your hands on the OpenCL binary driver.
This NVIDIA Linux x86/x86_64 driver has updates to the OpenCL SDK sample code, a new OpenCL SDK sample (named "oclsobelFilter"), an OpenCL compiler, and documentation. NVIDIA has not shared when they intend to publicly release their OpenCL Linux driver, but we would suspect around the August or September time-frame.
The Open Computing Language 1.0 specification
was released last year by the Khronos Group, the same consortium that controls OpenGL
plus other industry standards. NVIDIA is the first to provide hardware support for OpenCL on Linux, albeit through a proprietary driver and is currently only accessible to registered developers.
AMD is working on OpenCL support within their Catalyst Linux driver, but there is no ETA on when that will arrive in the hands of Linux customers. For open-source fans, an OpenCL state tracker
is being worked on to provide this GPGPU support to hardware that has a Gallium3D
