A researcher has broken the record for calculating the mathematical constant Pi, by using a number of computers running with Nvidia graphics cards. Ed Karrels of Santa Clara University used the GPUs in the graphics cards instead of normal computer processors in order to calculate pi to eight-quadrillion places.
NVIDIA took a major step towards spurring growth of its CUDA general-purpose code technology for video cards on Tuesday by posting the CUDA source code. Developers and education now have access to a variant on the LLVM compiler that will let them add new processor types and languages. The extension could see CUDA run on AMD's Radeon hardware, Intel's integrated graphics, and even use relatively old code like Fortran.
NVIDIA's is reportedly set to introduce a new flagship graphics card, which is said to carry the label GeForce GTX 590. Corroborating earlier leaks, the card will allegedly integrate dual GF110 GPUs with a combined 1024 CUDA cores and 3GB of memory, sources have told NordicHardware. The latest information suggests separate leak, which was tied to the name GTX 595, may have been an prototype of the 590.
NVIDIA today confirmed its second-ever GeForce 500 series chipset in a push to bring its new graphics to the mainstream. The GTX 570 has the exact same 480 cores as the old GTX 480 but, through the refined architecture, runs at a higher 732MHz main clock speed, 1.46GHz clock for each core and a 1.9GHz memory clock. It uses a narrower 320-bit memory interface (down from 384 bits) but, due to the combined improvements, has a higher texture fill rate bumped up from 42 billion to 43.9 billion pixels per second.
NVIDIA overnight quietly brought out its first 500-series GeForce notebook graphics. The GeForce GT 540M like the GTX 580 is primarily a clock speed increase with an increase in its main and effects core clock speeds to 672MHz and 1.34GHz each. It shares the GeForce GT 435M's 96 cores and 128-bit memory bandwidth.
A US patent filing published today has raised concerns as it could give Microsoft control of hardware-accelerated video encoding. A continuance of an application for "accelerated video encoding using a graphics processing unit" would cover the common technique of calculating motion for video processing with the video chipset in a computer rather than the regular, usually slower main CPU. Its techniques are broad and cover tricks like turning each frame into macroblocks to process them in parallel.
NVIDIA today confirmed its rumored entry-level video chipset, the GeForce GT 430. The design is targeted at home theater computers and other systems where video playback support is more important than raw 3D performance and now supports HDMI with passthrough audio. It can output HDMI 1.4a for full 3D video along with Dolby TrueHD and DTS-HD Master Audio surround sound.
NVIDIA chief Jen-Hsun Huang today at its GPU Technology Conference said his company would bring its CUDA general-purpose computing language directly to x86 chips. The approach developed with the Portland Group will let systems without NVIDIA cards handle the code. It will work best with multi-core processors and is seen as ideal for servers.
NVIDIA's first mainstream GeForce 400 notebook chipset, the GT 425M, has surfaced in leaks earlier this month. Semi-Accurate noted that the graphics core has been listed as showing in a 17-inch ASUS notebook, but with different features. Some list it as only a DirectX 10 chip, implying that it's only a refreshed 300M chip, while others mention DirectX 11 and that it would use a version of the Fermi architecture in the GTX 480M.
NVIDIA today brought out its first more frugal GeForce 400 series chipset in the form of the GeForce GTX 460. The recently leaked hardware uses the new 40 nanometer, GF104 chipset and is actually in some areas faster than the GTX 465. It has fewer stream (visual rendering) processors, at 336 versus 352, but has more texture addresses at 56 compared to 44; it also has a faster clock speeds across the board with a 675MHz core, 1.35GHz shader (effect) clock speeds, and a 900MHz actual speed for its GDDR5 memory.

Remote S for Tesla Apple Watch app drives car out
Developer Allen Wong has created the Remote S for Tesla app, which can be used to remotely activate the Model S electric car via an Apple Watch, and drive it a short distance. Aside from providing data about the car and some basic function controls, the unofficial app uses the manufacturer's Summon command to allow the car to turn on, exit the garage, and park near to the user's location. The app is available to purchase from the App Store for $10. http://apple.co/1PprF4t
Seagate 3TB unreliability suit expands
The Seagate 3TB class-action hard drive lawsuit has been expanded to more devices. The expanded suit, filed today, now includes Seagate's Barracuda 3TB Hard Disk Drive, Desktop HDD 3TB, Backup Plus 3TB External Hard Disk Drive, GoFlex 3TB External Hard Disk Drive, or any other Seagate hard drive with model number ST3000DM001. The law firm, Hagens Berman, is seeking information from consumers such as time in service, purchase price, and the nature of any drive received in return from Seagate as a replacement for a failed unit. http://bit.ly/1Pc34Cq
BlackBerry Canada, Florida hit with layoffs
The BlackBerry campus has reportedly been wracked with layoffs. Sources familiar with the company's Waterloo office staffing claim that close to 35 percent of the local workforce has been laid off, with the deepest cuts being made in the BlackBerry 10 OS and hardware teams. Additionally, the state of Florida has been officially notified that the company's Sunrise facility will see 75 people fired. Enthusiast site Mobilesyrup puts the layoffs at around 1000 total. http://bit.ly/1Pc1Rep
Instagram tests multiple account support for iOS
Instagram is trialling support for multiple accounts in its iPhone app with a small number of users. The Facebook-owned photo sharing service confirmed the reports of the tests to TechCrunch, which will allow a single user to manage more than a single account within the app, transferring between two or three accounts with a few taps. It is unclear when the feature will roll out to the public, but it has previously tested it with the Android version of the app since November. http://tcrn.ch/1SPKEKh
Foxconn CEO declares Sharp deal near done
The Foxconn bid for Sharp is allegedly only waiting on specific details of the deal. Foxconn CEO Terry Gou has declared that his company has privileged negotiation rights for the Apple iPhone screen supplier, saying that "we have a consensus, the rest is a process ... I don't see a problem completing this process." Gou hopes the deal, worth up to $5.6 billion, will be formalized by the end of February. http://reut.rs/1SPEQjN
MIT demoes 'Eyeriss' AI chip for mobile
At the International Solid State Circuits Conference in San Francisco this week, MIT researchers presented a new chip designed specifically to implement neural networks. The researchers claim that "Eyeriss" is 10 times as efficient as a mobile GPU, so it could enable mobile devices to run artificial-intelligence algorithms such as Siri or Cortana, rather than uploading all data to a remote server for processing. http://bit.ly/1TISJBe
