The Khronos Group, an open consortium of hardware and software companies responsible for the OpenCL specification, announces the immediate availability of the OpenCL 2.2, SYCL 2.2 and SPIR-V 1.1 provisional specifications. The new additions improve parallel programming as well as bring the Vulkan graphics shaders to OpenCL.
The Khronos Group, an open consortium of leading hardware and software companies, today announced the availability of technical previews of the new Vulkan open-standard API for high-efficiency access to graphics and computing on modern GPUs used in a wide variety of devices. This ground-up design, previously referred to as the Next Generation OpenGL Initiative, provides applications direct control over GPU acceleration for maximized performance and predictability, and uses Khronos' new SPIR-V specification for shading language flexibility.
One of the many exciting new features of the Mac Pro (late 2013) is Apple's choice to opt for dual AMD FirePro workstation GPUs as standard fitment, which certainly caught the eye of many observers. The previous generation Mac Pros included the option to fit dual CPUs, but as you can tell from the radical external redesign of the Mac Pro that Apple has fundamentally rethought its approach to the Mac workstation. Apple has chosen to adopt a dual-GPU configuration as standard fitment to leverage the massive processing power in GPU architecture. The biggest performance gains in certain professional applications come through harnessing the processing power in GPUs, rather than the CPU. To this extent, Apple has worked closely with AMD to develop three custom GPU solutions for the Mac Pro, to help Mac users tap into the power of AMD's Graphics Core Next (GCN) microarchitecture for parallel processing using the OpenCL framework.
An unofficial, pre-release benchmarking of Intel's upcoming Ivy Bridge architecture has shown an overall speed up, but most of all in graphics. Testing at AnandTech of a 3.5GHz, quad Core i7-3770K desktop chip has shown that the Intel HD 4000 integrated video is about 20 to 40 percent faster than the 3000 video on a roughly comparable earlier Core i7 using the current Sandy Bridge architecture. While still trailing behind AMD's Fusion in an A8 chip, it's enough to make games playable that wouldn't have been practical otherwise, such as running Skyrim smoothly at 1680x1050 and medium detail.
Imagination Technologies outlined some plans for its far and near futures after Electronista stopped by its Mobile World Congress booth on Monday. The PowerVR developer showed a demo of a real-time raytracing graphics engine, where an app calculates the paths of individual light beams in a scene, that it expects to reach mobile devices. As shown in a demo running on a Mac, it could use surface properties rather than unchanging textures to generate the chrome effect on a car, even reflecting another car which in turn had a reflection of the sky.
In a surprise step, Apple on Thursday gave developers a preview version of OS X Mountain Lion, the next significant update to the core OS. The new version is directly influenced by iOS 5 and includes Notification Center, Reminders, Notes, Game Center, and Twitter integration, with iCloud syncing where it's relevant. AirPlay Mirroring is also new to the Mac and shares exactly what's on screen through an Apple TV.
AMD took its Radeon HD 7000 series to the starter level quickly on Wednesday. The Radeon HD 7750 and 7750 GHz Edition step back in visual processor counts versus the 6700 line, from 720 and 800 cores to 512 and 640 respectively, but make up for it through more than a year's worth of technology. Both the new overall architecture and a shrink to a leaner 28 nanometer building process let the 7750 and 7770 climb to 800MHz and 1GHz core speeds (up from 700MHz and 850MHz).
Apple's long-rumored Mac Pro update could signal a return to NVIDIA for graphics based on claims about production progress on Tuesday. The company had reportedly been soured based on is experience with drivers and hardware failures, MIC Gadget heard. Instead, it would use NVIDIA's Kepler hardware, although which exact parts weren't mentioned.
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.
The desktop versions of Intel's Ivy Bridge processors have most of their details outlined in full through a roadmap discovered this week. The X-Bit Labs copy shows all the chips falling under the 3000 series in the same Core i3, i5, and i7 tiers, with four cores still the maximum for non-Extreme chips. Clock speeds would have a higher baseline, starting with a 2.7GHz Core i5 (3.2GHz after Turbo Boost) and peaking at a 3.5GHz Core i7 (3.9GHz).

Twitter stickers slowly roll out to users
Twitter has introduced "stickers," allowing users to add extra graphical elements to their photos before uploading them to the micro-blogging service. A library of hundreds of accessories, props, and emoji will be available to use as stickers, which can be resized, rotated, and placed anywhere on the photograph. Images with stickers will also become searchable with viewers able to select a sticker to see how others use the same graphic in their own posts. Twitter advises stickers will be rolling out to users over the next few weeks, and will work on both the mobile apps and through the browser. http://bit.ly/29bbwUE
French show carries on with iPhones
Following a prolonged power loss in a French TV studio, the crew was able to use a combination of limited studio lighting and a number of iPhones to continue taping the Saturday episode of talk show On n'est pas couché ("We're Still Awake"), using the resulting footage in the first edited episode. The Plus-model iPhones used for the impromptu shoot completion were either iPhone 6 Plusses (which shoot in 1080p) or 6s Plus models (which can shoot in 4K). The decision to use the iPhones to complete the show was made after a power outage at France 2's studio stretched to more than three hours. http://bit.ly/299wqDt
Scrivener for iOS to arrive in late July
For some long-time Scrivener users, to quote Paul Simon, "these are the days of miracle and wonders." As it marks its 10th anniversary in business, developer Keith Blount has announced that the long-awaited iOS version of his creative-writing tool Scrivener is to be submitted to the App Store, following strong praise from beta-testers. The program, expected in late July, will sell for $20 and work with both the iPad and iPhone. When we interviewed Blount last January, he added that Scrivener 3 for Mac would follow along shorty afterwards. http://bit.ly/2901XLE
WhatsApp now handles over 100M calls daily
WhatsApp is celebrating that it is being used for over 100 million calls every day. In a brief notice, the Facebook-owned messaging platform advises the voice-calling feature it rolled out to its users last year now deals with an average of over 1,100 calls initiated per second. Earlier this year, it increased the security of its calls and other messages, by introducing end-to-end encryption on all platforms. http://bit.ly/292HqCX
Adele's '25' album now streaming
Recording artist Adele has "pulled a Kanye" after saying that her current album "25" would not be available for streaming. The seven-month-old record, which has yielded a number of hit singles, is now available for streaming on all the major streaming services, such as Apple Music and Spotify, as of today in most major markets, with worldwide distribution to come. Reportedly, the singer had demanded streaming be limited to paid subscribers -- a condition that has hurt some streamers with artists, who aren't paid royalties for free or trial listens . Apple pays performers its normal royalty rates during its free trial, avoiding the issue -- and having repeated success in both signing up exclusives and placing those exclusives into the top of the charts. http://ti.me/28U7NOu
