New details on Intel's upcoming 14nm Xeon Phi (codenamed Knights Landing) suggests that the chip giant is targeting a huge increase in performance, throughput, and total TFLOP count with the next-gen MIC (Many Integrated Core) card. Knights Landing will be the first ground-up redesign of Intel's MIC architecture -- the original Knights Ferry card was a repurposed Larrabee GPU, while the current Knights Corner-based MIC still has texture units integrated on-die left over from its GPU roots. RealWorldTech has published an expose on the upcoming architecture, blending what we know of the new design with some intelligent speculation about its overall structure and capabilities. Knights Landing will...

At the International Supercomputing Conference today, Intel announced that Knights corner, the company's first commercial Many Integrated Core (MIC) product will ship commercially in 2012. The Descendent of the Processor Formerly Known as Larrabee also gets a new brand name -- Xeon Phi. The idea behind Intel's new push is that the highly efficient Xeon E5 architecture (eight-core Sandy Bridge on 32nm) fuels the basic x86 cluster, while the Many Integrated Core CPUs that grew out of the failed Larrabee GPU offer unparalleled performance scaling and break new ground. Sounds interesting enough doesn't it? Intel Announces MIC Xeon Phi, Aims For Exascale Computing...

Nvidia isn't happy with what it sees as the free pass Intel's upcoming Many Integrated Core (MIC) architecture has gotten on the software front, and it's taken to the blogosphere to challenge it. The post begins with a lengthy discussion of what Nvidia is calling its "hybrid architecture," in which a CPU and GPU get together for great fun and massive execution of properly distributed workloads. The post is conveniently timed to land just before the Texas Advanced Computing Center's (TACC) joint symposium with Intel on highly parallel computing, which kicks off next week. What Nvidia takes issue with, according to the blog, is the idea that using an x86-compatible product like Knights Corner,...

At the supercomputing conference SC2011 today, Intel offered up performance details of its upcoming Xeon E5 processors and demoed their Knights Corner many integrated core (MIC) solution. The new Xeons won't be broadly available until the first half of 2012, but Santa Clara has been shipping the new chips to "a small number of cloud and HPC customers" since September. The new E5 family is based on the same core as the 3960X Intel launched yesterday, but the company has been surprisingly slow to ramp the CPUs for mass production. Rajeeb Hazra, general manager of the Intel Datacenter and Connected Systems Group, stated that demand for the new chips was stronger than anything Intel had seen before....

Nvidia and HP have developed a limited edition GPU Starter Kit meant to provide a drop-shipped means for anyone interested in developing for HPC applications. The term 'starter kit' is very nearly a misnomer, as the package deal provides a system more than sufficient to get the ball rolling. The system contains eight ProLiant SL390 G7 servers, packed full of 24 M2070 GPUs, 16 CPUs, and its preconfigured with CUDA 4.0. The servers, presumably loaded with quad-cores, offer a respectable 32-cores of additional CPU power in addition to the copious amounts of GPU performance. The M2070 GPU that's included in the package is a Fermi-based part, with 6GB of RAM per GPU. According to Nvidia, the $99,000...

After Intel canceled Larrabee and announced it would repurpose the project for high-performance computing, little was said of what would happen to the company's various gaming-related IPs. It's therefore somewhat surprising to hear that Havok, the physics SDK developer Intel bought several years ago, has recently acquired Trinigy and that company's Vision Engine. The Vision Engine is a cross-platform development environment that supports Windows (DX9-11), the XBox 360, PS3, Wii, and the upcoming PlayStation Vita; iOS and Android support are both supposedly coming soon. The company claims that the engine is optimized to take advantage of multithreading on both x86 and non-x86 processors and includes...

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 CPU based on Intel's original Pentium architecture (P54C). Modifications include complete cache coherency,...

Six months ago, we covered a story in which Nvidia's chief scientist, Bill Dally, made a number of sweeping claims regarding the superiority of GPUs. Six months later he's again attacking traditional microprocessors with another broad series of accusations. As before, in our opinion, he uses far too broad a brush. Dally's basic claim is that modern CPUs are held back by legacy design. That's not particularly controversial, but he doesn't stop there. Referring to modern CPUs, Dally says:They have branch predictors that predict a branch every cycle whether the program branches or not -- that burns gobs of power. They reorder instructions to hide memory latency. That burns a lot of power. They carry...

If you're a fan of GPGPU computing this is turning out to be an interesting week. At SC10 in New Orleans, Intel has been demoing and discussing its Knights Ferry development platform. Knights Ferry, which Intel refers to as a MIC (Many Integrated Core) platform, is the phoenix rising rising from the ashes of Larrabee. Future MIC products (Knights Ferry is a development prototype, the first commercial product will be called Knights Corner) will mesh x86 compatibility with a level of parallelism typically found only in cluster nodes. Intel's Knights Ferry Knights Ferry contains 32 indepedent x86 cores with quad HyperThreading, fits into a PCIe 2.0 slot, and offers up to 2GB of DDR5 memory per card....

When the Federal Trade Commission (FTC) settled their investigation of Intel, one of the stipulations of the agreement was that Intel would continue to support the PCI Express standard for the next six years. Intel agreed to all the FTC's demands (without actually admitting that it did anything wrong), but Intel's upcoming Oak Trail Atom platform presented something of a conundrum. Oak Trail was finalized long before the FTC and Intel began negotiating, which means Santa Clara could have been banned from shipping the platform. The FTC and Intel have jointly announced an agreement covering Oak Trail that allows Intel to sell the platform without adding PCIe support—for now. Come 2013, all...

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 of Intel's hardware will be the fact that it's based on the ubiquitous x86 standard—something...

At the time of this writing, the FTC's investigation into Intel's alleged monopolistic abuses is on hold as the government attempts to negotiate a settlement with the CPU and chipset manufacturer. If these negotiations don't result in a deal by July 22, the case returns to court, with arguments currently scheduled to begin on September 15. Intel is no stranger to these sorts of lawsuits; between AMD and the EU, the CPU giant has been battling such allegations for years. The lawsuit between NV and Intel, however, rests on different points than the AMD/Intel allegations. Here, the battle is over whether or not Intel's already-negotiated agreements with NVIDIA give the latter permission to produce...

When we last checked in on Project Offset, the visually impressive game was facing an uncertain future. Intel recently released an update on PO's development status, but unfortunately it's not what we were hoping for. Having completely abandoned Larrabee as a GPU product, Intel saw no further reason to keep the dev team around. When queried, Intel told BigDownload the following: Intel purchased Offset Software to improve our game development knowledge-base and to further Intel's visual computing technology development expertise, helping the company offer robust products, support, and tools to customers. With the recent changes in our product roadmap, some of the resources and technologies from...
