nVidia Outs CUDA 6
Nvidia has made the latest GPU programming language CUDA 6 Release Candidate available for developers to download for free.
The release arrives with several new features and improvements to make parallel programming “better, faster and easier” for developers creating next generation scientific, engineering, enterprise and other applications.
Nvidia has aggressively promoted its CUDA programming language as a way for developers to exploit the floating point performance of its GPUs. Available now, the CUDA 6 Release Candidate brings a major new update in unified memory access, which lets CUDA applications access CPU and GPU memory without the need to manually copy data from one to the other.
“This is a major time saver that simplifies the programming process, and makes it easier for programmers to add GPU acceleration in a wider range of applications,” Nvidia said in a blog post on Thursday.
There’s also the addition of “drop-in libraries”, which Nvidia said will accelerate applications by up to eight times.
“The new drop-in libraries can automatically accelerate your BLAS and FFTW calculations by simply replacing the existing CPU-only BLAS or FFTW library with the new, GPU-accelerated equivalent,” the chip designer added.
Multi-GPU Scaling has also been added to the CUDA 6 programming language, introducing re-designed BLAS and FFT GPU libraries that automatically scale performance across up to eight GPUs in a single node. Nvidia said this provides over nine teraflops of double-precision performance per node, supporting larger workloads of up to 512GB in size, more than it’s supported before.
“In addition to the new features, the CUDA 6 platform offers a full suite of programming tools, GPU-accelerated math libraries, documentation and programming guides,” Nvidia said.
The previous CUDA 5.5 Release Candidate was issued last June, and added support for ARM based processors.
Aside from ARM support, Nvidia also improved Hyper-Q support in CUDA 5.5, which allowed developers to use MPI workload prioritisation. The firm also touted improved performance analysis and improved performance for cross-compilation on x86 processors.
Is AMD Worried?
AMD’s Mantle has been a hot topic for quite some time and despite its delayed birth, it has finally came delivered performance in Battlefield 4. Microsoft is not sleeping it has its own answer to Mantle that we mentioned here.
Oddly enough we heard some industry people calling it DirectX 12 or DirectX Next but it looks like Microsoft is getting ready to finally update the next generation DirectX. From what we heard the next generation DirectX will fix some of the driver overhead problems that were addressed by Mantle, which is a good thing for the whole industry and of course gamers.
AMD got back to us officially stating that “AMD would like you to know that it supports and celebrates a direction for game development that is aligned with AMD’s vision of lower-level, ‘closer to the metal’ graphics APIs for PC gaming. While industry experts expect this to take some time, developers can immediately leverage efficient API design using Mantle. “
AMD also told us that we can expect some information about this at the Game Developers Conference that starts on March 17th, or in less than two weeks from now.
We have a feeling that Microsoft is finally ready to talk about DirectX Next, DirectX 11.X, DirectX 12 or whatever they end up calling it, and we would not be surprised to see Nvidia 20nm Maxwell chips to support this API, as well as future GPUs from AMD, possibly again 20nm parts.
Is Samsung Ditching Android?

Comments Off on Is Samsung Ditching Android?
Samsung appears to have delivered a huge snuff to Android OS maker Google. Samsung’s new smartwatch Gear 2 and Gear 2 Neo, the sequels to the poorly reviewed original Galaxy Gear are going to ship without Android.
Instead, the new Gears run Tizen, another open source operating system that Samsung, Intel, and others are working on. It is starting to look like Samsung wants to distance itself from its reliance on Google for software and services.
Samsung’s official reason is that Tizen has better battery life and performance. The new Gears can get up to an extra two days of battery life by running Tizen, even though they have the same size battery. The Galaxy Gear barely made it through a day on one charge.
To be fair Android isn’t optimized to run on wearable devices like smart watches, but Samsung didn’t want to wait around for Google to catch up. It was clearly concerned about beating Apple to market. So far Apple has not shown up.
Is Ethernet For Autos?

Comments Off on Is Ethernet For Autos?
The most ubiquitous local area networking technology used by large companies may be packing its bags for a road trip.
As in-vehicle electronics become more sophisticated to support autonomous driving, cameras, and infotainment systems, Ethernet has become a top contender for connecting them.
For example, the BMW X5 automobile, released last year, used single-pair twisted wire, 100Mbps Ethernet to connect its driver-assistance cameras.
Paris-based Parrot, which supplies mobile accessories to automakers BMW, Hyundai and others, has developed in-car Ethernet. Its first Ethernet-connected systems could hit the market as soon as 2015, says Eric Riyahi, executive vice president of global operations.
Parrot’s new Ethernet-based Audio Video Bridging (AVB) technology uses Broadcom’s BroadR-Reach automotive Ethernet controller chips.
The AVB technology’s network management capabilities allows automakers to control the timing of data streams between specific network nodes in a vehicle and controls the bandwidth in order to manage competing data traffic.
Ethernet’s greater bandwidth could provide drivers with turn-by-turn navigation while a front-seat passenger streams music from the Internet, and each back-seat passenger watches streaming videos on separate displays.
“In-car Ethernet is seen as a very promising way to provide the needed bandwidth for coming new applications within the fields of connectivity, infotainment and safety,” said Hans Alminger, senior manager for Diagnostics & ECU Platform at Volvo, in a statement.
Ethernet was initially used by automakers only for on-board diagnostics. But as automotive electronics advanced, the technology has found a place in advanced driver assistance systems and infotainment platforms.
Many manufacturers also use Ethernet to connect rear vision cameras to a car’s infotainment or safety system, said Patrick Popp, chief technology officer of Automotive at TE Connectivity, a maker of car antennas and other automobile communications parts.
Currently, however, there are as many as nine proprietary auto networking specifications, including LIN, CAN/CAN-FD, MOST and FlexRay. FlexRay, for example, has a 10Mbps transmission rate. Ethernet could increase that 10 fold or more.
The effort to create a single vehicle Ethernet standard is being lead by Open Alliance and the IEEE 802.3 working group. The groups are working to establish 100Mbps and 1Gbps Ethernet as de facto standards.
The first automotive Ethernet standard draft is expected this year.
The Open Alliance claims more than 200 members, including General Motors, Ford, Daimler, Honda, Hyundai, BMW, Toyota, Volkswagen. Jaguar Land Rover, Renault, Volvo, Bosch, Freescale and Harman.
Broadcom, which makes electronic control unit chips for automobiles, is a member of the Open Alliance and is working on the effort to standardize automotive Ethernet.
What Do Smaller Controllers Mean?
If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.
The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.
Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.
The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.
Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.
Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.
This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.
Ubuntu Cross-Platform Delayed
Ubuntu will not offer cross-platform apps as soon as it had hoped.
Canonical had raised hopes that its plan for Ubuntu to span PCs and mobile devices would be realised with the upcoming Ubuntu 14.04 release, providing a write-once, run-on-many template similar to that planned by Google for its Chrome OS and Android app convergence.
This is already possible on paper and the infrastructure is in place on smartphone and tablet versions of Ubuntu through its new Unity 8 user interface.
However, Canonical has decided to postpone the rollout of Unity 8 for desktop machines, citing security concerns, and it will now not appear along with the Mir display server this coming autumn.
This will apply only to apps in the Ubuntu store, and in the true spirit of open source, anyone choosing to step outside that ecosystem will be able to test the converged Ubuntu before then.
Ubuntu community manager Jono Bacon told Ars Technica, “We don’t plan on shipping apps in the new converged store on the desktop until Unity 8 and Mir lands.
“The reason is that we use app insulation to (a) run apps securely and (b) not require manual reviews (so we can speed up the time to get apps in the store). With our plan to move to Mir, our app insulation doesn’t currently insulate against X apps sniffing events in other X apps. As such, while Ubuntu SDK apps in click packages will run on today’s Unity 7 desktop, we don’t want to make them readily available to users until we ship Mir and have this final security consideration in place.
“Now, if a core-dev or motu wants to manually review an Ubuntu SDK app and ship it in the normal main/universe archives, the security concern is then taken care of with a manual review, but we are not recommending this workflow due to the strain of manual reviews.”
As well as the aforementioned security issues, there are still concerns that cross-platform apps don’t look quite as good on the desktop as native desktop versions and the intervening six months will be used to polish the user experience.
Getting the holistic experience right is essential for Ubuntu in order to attract OEMs to the converged operating system. Attempts to crowdfund its own Ubuntu handset fell short of its ambitious $20m target, despite raising $10.2 million, the single largest crowdfunding total to date.
Samsung Joins OpenPower
Samsung has joined Google, Mellanox, Nvidia and other tech companies as part of IBM’s OpenPower Consortium. The OpenPower Consortium is working toward giving developers access to an expanded and open set of server technologies to improve data centre hardware using chip designs based on the IBM Power architecture.
Last summer, IBM announced the formation of the consortium, following its decision to license the Power architecture. The OpenPower Foundation, the actual entity behind the consortium, opened up the Power architecture technology, including specs, firmware and software under a license. Firmware is offered as open source. Originally, OpenPower was the brand of a range of System p servers from IBM that utilized the Power5 CPU. Samsung’s products currently utilize both x86 and ARM-based processors.
The intention of the consortium is to develop advanced servers, networking, storage and GPU-acceleration technology for new products. The four priority technical areas for development are system software, application software, open server development platform and hardware architecture. Along with its announcement of Samsung’s membership, the organization said that Gordon MacKean, Google’s engineering director of the platforms group, will now become chairman of the group. Nvidia has said it will use its graphics processors on Power-based hardware, and Tyan will be releasing a Power-based server, the first one outside IBM.
Did Intel Kill Bay Trail?
Intel has decided that some of its budget Bay Trail parts have been out evolved and flung them into a tar pit. According to CPU World the parts first appeared in September. Intel released budget Bay Trail systems on a chip for mobile and desktop markets, under Celeron and Pentium brands.
They were manufactured on 22nm technology, and featured such enhancements as greater number of CPU cores, higher clock speeds, beefed up graphics unit, not to mention an out-of-order microarchitecture, that improved per-clock CPU performance by up to 30 per cent faster compared to their predecessors. With this performance goodness it is a little surprising the Intel has decided that all the all Bay Trail SoCs will be discontinued in a matter of a few months. Details of the planned discontinuation were published this week by Intel in several Product Change Notification documents.
The Desktop Pentium J2850, along with mobile Celeron N2810 and Pentium N3510 are already End of Lifed and its last orders will be in two weeks, on February 11. The chips will ship until April 25, 2014. Also retired are mobile Celeron N2806, N2815, N2820, N2920, and Pentium N3520. Their EOL date is April 11, 2014, and they will ship until May 30, 2014. On August 22, 2014, Intel is going to discontinue Celeron J1750, J1850, N2805 and N2910. The “J” models are desktop processors, and the “N” are mobile ones. There is no word on Z-series Bay Trail-T parts, none appear to be EOL’d at this time.
Furthermore, on the same date Intel will retire Core i7-3940XM Extreme Edition, and boxed and tray versions of Core i7-3840QM and i7-3740QM CPUs. The last shipment date for the Celerons and Core i7s is February 6, 2015.
IBM’s Watson Goes To Africa
IBM has detailed plans to apply its Watson supercomputer the critical development issues facing Africa.
The machine is capable of holding more intelligent conversations than most Big Brother contestants, and in 2011 it beat human contestants on the US TV game show Jeopardy.
However, in Africa it will be used to help solve the pressing problems facing the continent such as agricultural patterns and famine relief.
The initiative, named Project Lucy after the earliest human remains discovered on the continent, will take 10 years and is expected to cost $100m.
“I believe it will spur a whole era of innovation for entrepreneurs here,” IBM CEO Ginni Rometty told delegates at a conference on Wednesday.
“Data… needs to be refined. It will determine undisputed winners and losers across every industry.”
The technology will be used to find ways to enable the developing world to leapfrog over stages of development that have hitherto been too expensive.
One example cited was Nigeria, where two companies have already committed to use Project Lucy to analyse the poorly maintained road system and determine project priorities for repair.
IBM recently announced that it will invest $1bn to spin off Watson into a separate business unit, however this could be quite a gamble as Reuters reported that although Watson has proved to be a quantum leap, it has yet to make any significant money for the company, netting less than $100m in the past three years.
Sony Exits PC Business
Sony will unload its struggling PC business to a Japanese investment firm, the company said Thursday, raising the possibility that the “Vaio” brand could all but disappear from markets outside Japan.
Tokyo-based investment fund Japan Industrial Partners (JIP) will operate the Vaio PC brand under a newly established firm and initially sell PCs in Japan only.
In another reform aimed at bolstering its restructuring efforts, Sony also said it would turn its beleaguered TV business into a subsidiary.
The moves come as Sony said it now expects a net loss of $1.1 billion for the year to the end of March, a reversal of its October profit forecast.
Vaio, which Sony introduced in 1996, looks set to vanish from most markets, at least for short term, as the new company will initially concentrate on selling consumer and corporate PCs in Japan. Whether or not Sony will continue to produce products under the Vaio brand remains to be seen, Sony said.
Although Sony is selling its PC business, it will continue to produce tablet computers, part of its renewed focus on mobile devices including smartphones.
Sony did not put a price on the sale. Sony will take a 5% stake in the new firm, it said.
Sony will stop making and selling PCs after its 2014 Spring lineup launch, but about 250 to 300 Sony staff, including some from a subsidiary that produces TV sets, cameras and computers at factories in Japan, will be hired by the new company, which is to be based at the hub of Sony’s current PC business in Japan’s Nagano Prefecture.
Meanwhile, Sony said it will turn its TV business, which has faced a decade of losses, into a wholly owned subsidiary by July 2014.
