Pa4All is an open-source environment to do source-to-source transformations on C and Fortran programs for parallelizing, optimizing and instrumenting. The source-to-source approach allows you to capitalize on the source code and generate other sources that can be used by the better back-ends available: optimized compilers for a given processor, vendor compilers for embedded processors, CUDA or OpenCL for GPU, OpenMP, MPI.
Are you having trouble getting start in OpenCL development. Enj has started a tutorial series aimed at developers trying to learn OpenCL from the bottom up, with a focus on practicality.
cebas Visual Technology announced the upcoming release of their cebas’ suite of finalRender rendering solutions for 3ds Max, Maya and CINEMA 4D will fully support OpenCL. If you are going to SIGGRAPH 2010 in Los Angeles, be sure to stop in at the cebas booth #314 to view a demonstration.
Stanford's Folding@Home is working on an OpenCL enabled client. However, due to optimization and performance issues, the client is not ready quite yet. The Folding@Home developers need your help to optimize the new GPU OpenCL client. From the Folding@Home blog "We are also working to finish our OpenCL port for ATI GPUs to support GPU3 on ATI, but there are still performance issues for OpenCL on both NVIDIA and ATI which are holding back this release."
The OpenCL Development Kit for Linux on Power is an IBM implementation of the OpenCL 1.0 Specification. This implementation is for Power hardware running the Linux operating system and has been tested on the IBM BladeCenter QS22, JS22, JS23, and JS43 systems running Red Hat Enterprise Linux 5.4 or 5.5, and the IBM Power 755 server running Red Hat Enterprise Linux 5.5.
Learn and share ideas at the Perth GPU Users group. Founded to bring together GPU users from all fields and experience levels in Western Australia. Topics of discussion include general GPU computing, GPGPU, CUDA, OpenCL, OpenGL, DirectCompute, DirectX and related technologies. The next meetup is tentatively scheduled for June 23rd at the ground Floor Physics Building, University of Western Australia (Crawley Campus) 35 Stirling Highway, Crawley WA. 5:30pm - 7pm. You can find additional Khronos API related events and meet-ups on the Khronos Group events page.
Erik Rainey has released a series of utilities aimed at making OpenCL easier to use under the Apache 2.0 License. The environment includes: clCompiler which generates both binary outputs and precompiled headers which can be used in conjunction with clEnvironment; clQuery allows you to print all known information about a OpenCL data type. clPid, clYUV and clImgFilter are examples of how to use the utilities to create a compile time kernel make it a dependency in you makefiles and then use the clEnvironment to call your kernel. You can download the OpenCL Environment from github.
CMSoft brings a versatile and useful tool, Marching Cubes, adapted to GPU acceleration using OpenCL. Sample source code is available. Marching Cubes is an algorithm used in a very wide range of applications, including Medical visualizations such as CT and MRI scan images; Special 3D effects and 3D modelling of metaballs or metasurfaces: Analysis of oil reservoirs in the oil and gas industry and Reconstitution of surfaces whose data has been acquired through seismic methods.
The Khronos Group will be at SIGGRAPH 2010 this year in Los Angeles with their own booth. Visit Khronos at booth # 1201 and pickup a free laminated reference card for OpenCL and OpenGL as well as see some amazing demonstrations from Imagination Technologies, Rightware, HUONE, Vivante and DMP. As well, there will be a number of BOFs this year including the much anticipated OpenGL BOF, COLLADA, OpenCL, Mobile API and new this year, the WebGL BOF. Be sure not to miss out by registering for your spot today. Space is limited so please don't wait til the last minute. Complete details on all the events at SIGGRAPH that Khronos will be a part of are available online.
The Khronos™ Group today announced the ratification and public release of the OpenCL™ 1.1 specification, the latest version of the open, royalty-free standard for cross-platform, parallel programming of modern processors. OpenCL 1.1 adds significant functionality for enhanced parallel programming flexibility, functionality and performance including:
- New data types including 3-component vectors and additional image formats;
- Handling commands from multiple hosts and processing buffers across multiple devices;
- Operations on regions of a buffer including read, write and copy of 1D, 2D or 3D rectangular regions;
- Enhanced use of events to drive and control command execution;
- Additional OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies;
- Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events.
