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.

Swift benchmarking suite goes open-source
Following the release of new betas for all its platforms, Apple on Monday also made a suite of 75 tools for benchmarking Swift-developed coding projects, including libraries for benchmarking functions, a utility for comparing the resulting metrics, and a driver for running them. The company says it is asking the community for help in developing additional benchmarks, as well as further "helper" libraries and overall code review for better stability and performance. Apple plans to include benchmark pull requests in Swift's new continuous integration system as well. http://bit.ly/1W8u0EU
Instagram now supporting multiple accounts
As reported earlier, Instagram is now rolling out support for multiple accounts (up to five) in version 7.1.5 of its iOS app. The feature has been one of the main attractions of third-party Instagram clients, but it is unclear if users must seek out an "add account" preference in the app; additionally, some users are reporting that the ability to add accounts has not yet been added. The company says notifications "depend on when you last logged in, and the number of devices that are logged into that account," suggesting not all notifications across accounts will appear when logged into a given one. http://bit.ly/1moh95p
Pictures of Galaxy S7, Edge leaked
New images have been leaked of Samsung's new Galaxy S7 and S7 Edge. The images of the Galaxy S7 are very similar to a draft leaked earlier this year, with a curved back reminiscent of the iPhone 3G with the normal Samsung camera hump in the upper center of the phone. The picture of the Galaxy S7 Edge as leaked is running a benchmark application showing modest improvements over the S6 line, if accurate. Both models are expected to be formally announced in a February 21 press event hosted by Samsung. http://bit.ly/20Gf07X
Bambooti wooden skins for MacBooks
Bambooti has introduced premium wooden skins for Apple laptops that allow users to customize any design or logo directly on the case. Each Bambooti skin is handcrafted from sustainably managed forests, and are hand sanded and spray-finished to create an ultra smooth exterior. Bambooti's wooden skins start at $65 on the fully-funded Kickstarter which includes a custom design or logo of the user's choice that will be engraved on the product. http://kck.st/1PhE6Sb
Apple Music in Taiwan, now up to 113 countries
Apple Music has now added its 113th country, Taiwan, to its expanding list of areas where it offers its paid subscription service. The price in the country will start at NT$150 (about $4.50 US) for an individual subscription, and that now includes (as it does in the rest of the world) the formerly free-but-ad-supported iTunes Radio feature, which as in other countries will be customized somewhat to offer channels of locally-popular music styles. Apple Music is now available in 16 countries and regions -- including China, India, Russia, and Japan -- where Spotify has not yet arrived.
Invisible wall mount for iPad Pro, mini
Computing hardware mounting company Wall-Smart has announced the availability the new "invisible" wall mount, with models for the iPad Pro, iPad Air 2 and iPad mini 4 -- all with no bezel. The invisible mount includes Power Over Ethernet to USB, which allows charging while in-wall, and is available for both drywall and solid surfaces such as solid wood panels or partition walls. Prices vary widely by iPad model, and required mounting hardware. http://bit.ly/1SE5jCO
Kingston buys IronKey secure USB tech
Kingston Digital today announced it has acquired the USB technology and assets of IronKey from Imation. In addition to Kingston's acquisition, encryption services leader DataLocker has purchased the IronKey Enterprise Management Services platform which provides centralized management to encrypted USB drives. Kingston and DataLocker claim that there will be no interruption in service provided, or available products as a result of the consolidations. http://bit.ly/1QQk9SZ
