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).

Fiat Chrysler adding Siri Eyes Free
On Friday, automaker Fiat Chrysler issued a software update for selected 2013-2015 model cars to allow Siri Eyes Free, the precursor to the more fully-featured CarPlay, to be compatible with the vehicles' infotainment systems, including steering wheel control. The 2013 through 2015 model Ram 1500/2500/3500, the 2013-2015 Dodge Viper, the 2014-2015 Dodge Durango, the 2014-2015 Jeep Cherokee and Grand Cherokee, and the 2015 models of Dodge Challenger and Charger, Jeep Renegade, and Chrysler 200 and 300 can be upgraded through the Unconnect touchscreen, visiting the Uconnect site and entering their 17-digit Vehicle ID, then downloading the update to a USB drive. Installation can take up to 45 minutes, and can only be done while the vehicle is in park. http://bit.ly/23f0sby
Tor Myhren starts as VP of Communications
After an initial announcement in December, Apple on Friday added former Grey Group chief creative officer Tor Myhren to its leadership roster as VP of Marketing Communications, placing the well-known ad exec in charge of Apple's advertising and Internet marketing efforts, as well as having a hand in packaging design. He will report directly to CEO Tim Cook, and is replacing the retired Hiroki Asai, who left Apple after 18 years with the company. Myhren is expected to continue Apple recent push into more "lifestyle" marketing rather than product-centric ads, such as the well-remembered "I'm a Mac" campaign from last decade. http://apple.co/1Wwf0Dd

Apple has updated Maps to include Spotlight Suggestions for Denmark, Norway, and Sweden, allowing users to search both internally and across the web on both Mac and iOS devices for data in Spotlight. In addition, the company has added Puerto Vallarta, Mexico and Akron, Ohio to the 3D Flyover feature, offering computer-enhanced aerial views of the two areas -- and has activated real-time traffic information for Thailand, which will augment services like reminders to incorporate estimated travel times for appointments, as an example. The company recently added Nearby searches to five countries, and rolled out transit directions for Montreal in Canada and Portland, Oregon. http://apple.co/1Lh1Zel
Verizon gives last offer, issues workers ultimatum
Verizon has offered striking workers its "last, best and final offer" following 10 months of protracted negotiations with union leaders. The latest offer comes on the back of 36,000 Verizon employees taking strike action two weeks ago. The proposal includes a 7.5 percent wage rise, better benefits and voluntary retirement incentive offers. The striking workers, mainly on from its fixed line operations, have claimed that Verizon has outsourced 5,000 jobs to workers overseas and that it has been deliberately hiring low-wage, non-union contractors. Verizon recently posted revenue of $32.2 billion for the March quarter. http://cnnmon.ie/26AmwSv
