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).

Cirrus creates Lightning-headphone dev kit
Apple supplier Cirrus Logic has introduced a MFi-compliant new development kit for companies interested in using Cirrus' chips to create Lightning-based headphones, which -- regardless of whether rumors about Apple dropping the analog headphone jack in its iPhone this fall -- can offer advantages to music-loving iOS device users. The kit mentions some of the advantages of an all-digital headset or headphone connector, including higher-bitrate support, a more customizable experience, and support for power and data transfer into headphone hardware. Several companies already make Lightning headphones, and Apple has supported the concept since June 2014. http://bit.ly/29giiZj
Apple Store app offers Procreate Pocket
The Apple Store app for iPhone, which periodically rewards users with free app gifts, is now offering the iPhone "Pocket" version of drawing app Procreate for those who have the free Apple Store app until July 28. Users who have redeemed the offer by navigating to the "Stores" tab of the app and swiping past the "iPhone Upgrade Program" banner to the "Procreate" banner have noted that only the limited Pocket (iPhone) version of the app is available free, even if the Apple Store app is installed and the offer redeemed on an iPad. The Pocket version currently sells for $3 on the iOS App Store. [32.4MB]
Porsche adds CarPlay to 2017 Panamera

Apple employees testing wheelchair features
New features included in the forthcoming watchOS 3 are being tested by Apple retail store employees, including a new activity-tracking feature that has been designed with wheelchair users in mind. The move is slightly unusual in that, while retail employees have previously been used to test pre-release versions of OS X and iOS, this marks the first time they've been included in the otherwise developer-only watchOS betas. The company is said to have gone to great lengths to modify the activity tracker for wheelchair users, including changing the "time to stand" notification to "time to roll" and including two wheelchair-centric workout apps. http://bit.ly/2955JDa

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
