Netflix has long chased after methods of improving its movie recommendation algorithms, once even awarding a $1M prize to any team of people who could substantially improve on the then-current design. As part of that process, the company has been researching neural networks. Conventional neural networks are created with vast nodes of CPU clusters, often with several thousand cores in total. Netflix decided to go with something different, and built a neural network based on GPU cores. In theory, GPU cores could be ideal for building neural nets -- they offer huge numbers of cores already linked... Read more...
While Adobe is busily showing off its latest and greatest wares at NAB 2013 this week, AMD is banging the drum for the major upgrades that it helped bake into the next version of Adobe Premiere Pro software. While Mac users have of late enjoyed the graphical power of OpenCL with either NVIDIA or AMD graphics cards, Windows users were forced to use NVIDIA’s CUDA only. Now, however, AMD and Adobe have enabled OpenCL support on Windows systems with AMD APUs and GPUs. “Our customers require powerful systems that enable them to work quickly and efficiently. While we already support OpenCL... Read more...
Intel announced new drivers for its integrated HD 2500/4000 graphics (for 3rd generation Intel Core processors), and it did so in a somewhat refreshingly brief press release. The updates to the graphics drivers are for Windows 7 and Windows 8 systems (both 32-bit and 64-bit). Intel says that versions 15.31.3.3071 (32-bit) and 15.31.3.64.3071 (64-bit) bring a new driver architecture as well as optimzations designed to boost game performance by as much as 10% in some popular titles including Starcraft II, Batman: Arkham City, and WoW: Mists of Pandaria. Intel HD 2500/4000 graphics now have reduced... Read more...
We love benchmarks here at HH, so it’s always good news when another one comes down the pike. Today, Rightware released Basemark CL, an OpenCL benchmark aimed at desktop machines, with an embedded profile version in the offing. With Basemark CL, Rightware is attempting to deliver a benchmark that puts realistic stress on OpenCL implementations with image manipulations tests and physics tests. The software can run single or multiple tests and checks the bandwidth limitations between the CPU and GPU and also checks the extra computing power OpenCL affords a system. Rightware is positioning... Read more...
AMD has just released an updated version of their APP SDK, bringing it up to version 2.5. This latest release features a number of performance enhancements designed to exploit the increased CPU to GPU bandwidth available in the company’s APUs, in some cases achieving effective data transfer rates as high as 15GB per second with the latest AMD A-Series APUs, per the press release. “Improving performance and programmability on AMD platforms is a key initiative for us, and we work closely with developers to help us make the APU the best possible development platform,” said Manju...

Larrabee, Intel's once-vaunted, next-generation graphics card died years ago, but the CPU technology behind the would-be graphics card has lived on. Intel discussed the future of MIC/Knight's Corner today. After Larrabee was officially canceled, Intel repurposed the design and seeded development kits to appropriate market segments. MIC cards won't start shipping until the 22nm Knight's Corner chip is launched, but even the Knight's Ferry prototypes offer tantalizing hints at what future performance might be resemble. Like Larrabee, Knight's Corner (and future MIC products in general) utilize a... Read more...
The past 18 months have seen a significant evolution in browser graphics. Chrome, Firefox, Safari, and Opera have all added support for such standards as OpenCL, HTML5, and Direct2D acceleration. (HTML5 isn't a graphics standard, strictly speaking, but it allows the browser to handle certain activities that once required Flash plugins). Support for WebGL, a browser-friendly derivative of OpenGL, has been added to Firefox and Safari (with Chrome and Opera versions under development). Microsoft, however, has announced it won't be including WebGL support, claiming that the standard is far too insecure... Read more...
AMD's GPU solutions have come a long way since the company acquired ATI. The combined companies have competed very well against Nvidia for the past several years, at least at the consumer level. When it comes to HPC/GPGPU tools, however, Nvidia has had the market all to itself. Granted, the GPGPU market hasn't exactly exploded, but Nvidia has sunk a great deal of effort into developing PhysX and CUDA. AMD has announced a new suite of programming tools it plans to use to woo developers in the burgeoning field. "AMD is working closely with the developer community to make it easier to bring the benefits... Read more...
AMD is hosting its first AMD Fusion Developer Summit (AFDS) this year, from June 13-16. The conference will focus on OpenCL and Llano's performance capabilities under various related usage models. Sunnyvale is billing the event as a chance to participate and learn from experts, all in accordance with the company's belief that: "the computing industry is quietly undergoing a revolution bigger than any change it has seen since the semiconductor was first introduced: the rise of GPUs and APUs." Llano's die (rotated 90, in this case. The DX11 cores are to the left and occupy a significant chunk of... Read more...
For the past 3.5 years or so, NVIDIA has ardently advocated the GPU as a computational platform capable of solving almost any problem. One topic the company hasn't targeted, however, is the tremendous performance advantage the GPU could offer malware authors. The idea that a graphics card could double as a security hole isn't something we've heard before, but according to a paper by Giorgos Vasiliadis, Michalis Polychronakis and Sotiris Ionnidis, it's an attack vector whose popularity could boom in coming years. The trio argues that all the computational hardware that makes the GPU such an ideal... Read more...
At the GPU Technology Conference today, the CEO of NVIDIA, Jen-Hsun Huang, unveiled a new CUDA initiative, dubbed CUDA-x86. As the name implies, the new framework will allow developers to write CUDA code natively for x86. Don't confuse this announcement with the PhysX issues we discussed last month—when we spoke to NVIDIA back then we were told that certain legacy performance issues would be addressed in the next major version of the PhysX SDK. Porting CUDA to x86 is a smart move for NVIDIA given Intel's own intentions towards the high performance computing (HPC) market. One of the core advantages... Read more...
Earlier this week, we covered news that a California PS3 owner, Anthony Ventura, had filed a class action lawsuit against Sony, alleging that the company's decision to terminate the PS3's Linux support via firmware update constituted a false/deceptive marketing practice. While most PS3 owners never took advantage of the system's Linux capabilities, "Other OS" functionality is critical to the universities and institutions that have deployed PS3 clusters as high-performance compute farms. We talked with several project leads on the impact of Sony's decision, and what it means for low-cost supercomputing... Read more...

Last week, we covered NVIDIA's decision to disable PhysX support if the NV drivers detect the presence of an ATI product. Jump ahead seven days, and the utterly predictable has happened—end-users have found a way around NVIDIA's lockout and have re-enabled the one-two punch of ATI graphics and NVIDIA PhysX. Quick, kids: Can any of you guess what happens next? Over at NGOHQ, forum member Regeneration is claiming that the NVIDIA drivers published after the 185.85 WHQL series (this includes 186.18 through 191.07) also disable Ageia's original PPU add-on board if a non-NVIDIA GPU is installed. We've... Read more...
