When it comes to high-performance computing applications, OpenMP has long been the standard open-source API for the job. However, OpenCL is now emerging as a new challenger in the HPC space. According to Evans' Data Corp., OpenCL is now the second most popular HPC tool with almost 28% of developers using OpenCL, ahead of Intel's Threading Building Blocks (Source: AMD slideset). Evans also shows OpenCL adoption has increased since 2009. AMD has decided to step up its game by releasing optimization and development tools that fill in the gaps it sees in the OpenCL ecosystem.
Users of Apples recently released Final Cut Pro X will appreciate the most recent upgrade. FCP now includes OpenCL support for exporting your videos. According to OnlineVideo.net "I tested a few simple test projects, and saw some profound speed increases, particularly with an AVCHD clip with a Gaussian Noise effect applied. Not all producers will see these kind of benefits, but it’s nice to see OpenCL start to pay some real benefits."
The new Intel® OpenCL SDK 1.5 makes it easy for you to design, build, debug, and profile OpenCL applications running on the CPU device. Among the new features in this release is a beta OpenCL kernel debugger, a support for OpenCL profiling with Intel® GPA 4.2, seamless utilization of the Intel® AVX instruction set through the Implicit CPU Vectorization Module, and offline compiler support for Linux.
AMD announced that it has created drivers to enable support for the upcoming Windows 8 operating system on AMD-based tablets, netbooks, PCs and servers. AMD technology offers a compelling platform for the forthcoming Windows 8, with native support for Microsoft DirectX 11, C++ AMP, OpenCL and Accelerated HTML5, as well as planned support of DirectX 11.1 features.
The new AMD FirePro SDI-Link and V7900 SDI Professional Graphics Card address the market for real-time, GPU-accelerated post production and broadcast pipelines requiring Serial Digital Interface (SDI) input and output. AMD FirePro SDI-Link was announced with support from the premier players in the broadcast technology market: AJA, Bluefish444, Blackmagic Design, DELTACAST, DVS and Matrox. "Integrators in the broadcast and real-time video production market can now benefit from the latest advances in GPU acceleration," said Sandeep Gupte, general manager of professional graphics at AMD. Both cards offer extensive support for OpenCL 1.1 and OpenGL 4.2.
At the International Broadcasting Convention 2011NVIDIA introduced NVIDIA GPUDirect for Video. This technology enables application developers to deliver higher quality, more realistic on-air graphics -- or take faster advantage of the parallel processing power of the GPU for image processing. This is done by permitting industry-standard video I/O devices to communicate directly with NVIDIA professional Quadro and Tesla graphics processing units (GPUs) at ultra-low latency. Nick Rashby, President, AJA Video Systems says "this will allow developers whose apps support AJA video I/O products to take better advantage of the power of NVIDIA Quadro and Tesla GPUs, resulting in low-latency access for both graphics compositing and general purpose processing using CUDA or OpenCL, with all the I/O and performance they depend on from AJA."
libCL is an open-source parallel algorithm library written in C++ and OpenCL, released under the Apache 2.0 license. Based on a thin layer of wrapper classes for OpenCL and OpenGL are implementations of parallel algorithms ranging from simple primitives such as sorting, searching and algebra to complex systems of algorithms for computational research and visualization. libCL emerged out of OpenCL Studio, and as such integrates well with the development environment and its rich prototyping and visualization capabilities.
AMD announced that the latest FirePro professional graphics cards have been certifed for the OpenCL enabled Abaqus 6.11 finite element analysis (FEA) software. Abaqus, which takes advantage of the OpenCL™ industry standard, is a leading structural and multiphysics analysis solution which is used by a wide range of industries for simulating the lifelike performance of products throughout the design and manufacturing process.
Bryan Catanzaro, NVIDIA Research talks discuss the CUDA and OpenCL programming models, GPU architecture, and how to write high performance code on GPUs, illustrating with case studies from application domains such as image and video processing.
The SuperShaper is a small free tool that let's you explore the Super Formula in real-time. It uses OpenCL1.0 to evaluate the formula and OpenGL3.2 for rendering. For maximum performance OpenCL and OpenGL share buffers if possible. The latest version supports any OpenCL capable device in the system (CPU or GPU).
