Intel Unveils New Product Plans for High-Performance Computing

During the International Supercomputing Conference (ISC), Intel Corporation announced plans to deliver new products based on the Intel Many Integrated Core (MIC) architecture that will create platforms running at trillions of calculations per second, while also retaining the benefits of standard Intel processors.

Targeting high-performance computing segments such as exploration, scientific research and financial or climate simulation, the first product, codenamed "Knights Corner," will be made on Intel's 22-nanometer manufacturing (nm) process – using transistor structures as small as 22 billionths of a meter – and will use Moore's Law to scale to more than 50 Intel processing cores on a single chip. While the vast majority of workloads will still run best on award-winning Intel Xeon processors, Intel MIC architecture will help accelerate select highly parallel applications.

Intel Shelves Larrabee as a GPU Architecture

Intel has once again shelved plans to come back to the discrete graphics market, with the much talked about GPU codenamed Larrabee. In a recent post by Director, Product and Technology Media Relations Bill Kircos on the company blog, it was detailed that the company's priorities at the moment lie with releasing industry-leading processors that have the graphics-processing horsepower for everyday computing. The Intel HD graphics will only get better with the 2011 series of Core processors based on the Sandy Bridge architecture, where the iGPU core will be completely integrated with the processing complex.

An unexpected yield of the Larrabee program seems to be that Intel has now perfected many-core processors. Since Larrabee essentially is a multi-core processor with over 32 IA x86 cores that handle graphics workload, it could as well give Intel a CPU that is Godsent for heavy-duty HPC applications. Intel has already demonstrated a derivative of this architecture, and is looking to induct it into its Xeon series of enterprise processors.Source: Intel Blogs

Intel Larrabee Fails as a GPU Project

Intel's ambitious attempts at building a discrete GPU have been shelved, as reports emerge of the company canceling the silicon's first implementation as a GPU, but rather as a "software development platform for internal and external use." In a statement issued to, Intel spokesperson Nick Knupffer explained the company's current position of Larrabee, saying that development of Larrabee's silicon (the chip) and software were behind schedules. "Larrabee silicon and software development are behind where we hoped to be at this point in the project," he said. "As a result, our first Larrabee product will not be launched as a stand-alone, discrete graphics product, rather it will be used as a software development platform for internal and external use."

Larrabee as a discrete GPU made a lot of news in its short public-life, it was given much credibility as it was coming from Intel, an IT industry heavyweight. Earlier this year, Intel demonstrated a Larrabee-based product (including actual product design of the "Larrabee card"), at last month's SC'09 show. The company seemed to have avoided calling it a discrete GPU, instead a "computational co-processor for the Intel Xeon and Core families." It was reasonable in calling it that, since by design, Larrabee is a many-core processor which uses 32 IA cores interconnected by caches. At SC'09, Intel demonstrated its computational power which peaked at over 1 TFLOP, but not before overclocking it.

Larrabee Only by 2010

Last week, Intel announced its Visual Computing Research Center at Saarland University in Saarbrücken, Germany. During its opening ceremony, details emerged about when Intel plans to commercially introduce Larrabee, the company's take on graphics processing using x86-based parallelism. The company categorically stated that one could expect Larrabee to be out only by early 2010.

"I would expect volume introduction of this product to be early next year," said Intel chief executive Paul Otellini. Until now, Larrabee was known to be introduced coarsely around the 2009-2010 time-frame. "We always said it would launch in the 2009/2010 timeframe," said Intel spokesperson Nick Knupffer in an email to PC Magazine. "We are narrowing that timeframe. Larrabee is healthy and in our labs right now. There will be multiple versions of Larrabee over time. We are not releasing additional details at this time," he added. In the same event, Intel displayed a company slide with a die-shot of Larrabee, revealing what looked like the x86 processing elements. Sections of the media were abuzz with inferences drawn on the die-shot, some saying that it featured as many as 32 processing elements.Source: PC Magazine

Intel Larrabee Die Zoomed in

Intel chose the occasion of the opening ceremony for the Intel Visual Computing Institute at the Saarland University in Germany, to conduct a brief presentation about the visual computing technologies the company is currently working on. The focal point was Larrabee, the codename for Intel's upcoming "many-cores" processor that will play a significant role in Intel's visual computing foray way beyond integrated graphics. The die-shot reveals in intricate network of what look like the much talked-about x86 processing elements that bring about computing parallelism in Larrabee. Another slide briefly describes where Intel sees performance demands heading, saying that its growth is near-exponential with growth in common dataset sizes.

Intel Displays Larrabee Wafer at IDF Beijing

Earlier this week, Intel conducted the Intel Developer Forum (IDF): Spring 2009 event at Beijing, China. Among several presentations on the the architectural advancements of the company's products, that include Nehalem and its scalable platforms, perhaps the most interesting was a brief talk by Pat Gelsinger, Senior Vice President and General Manager of Intel's Digital Enterprise Group, on Larrabee. The term is Intel's first "many cores" architecture used to work as a graphics processor. The architecture will be thoroughly backed by low-level and high-level programming languages and tools by Intel.

French website took a timely snap off a webcast of the event, showing Gelsinger holding a 300 mm wafer of Larrabee dice. The theory that Intel has working prototypes of the GPU deep inside its labs gains weight. Making use of current-generation manufacturing technologies, Intel is scaling the performance of x86 processing elements, all 32+ of them. As you can faintly see from the wafer, Larrabee has a large die. It is reported that first generation of Larrabee will be built on the 45 nm manufacturing process. Products based on the architecture may arrive by late 2009, or early 2010. With the company kicking off its 32 nm production later this year, Larrabee may be built on the newer process a little later.


Quake 4 run Ray-tracing Enabled on Intel Larrabee

Part of the series of published slides by French website CanardPlus on slides part of the IDF event shows a picture of Quake 4 run with ray-tracing enabled on Intel's upcoming GPU codenamed Larrabee. The slide shows the advantages of ray-tracing, being accurate shadows, reflections, and the image looking more natural that what conventional shaders can achieve in bringing about.
