IBM launched its Power8 lineup of superscalar symmetric multiprocessors back in August 2013 at the Hot Chips conference, and the first systems became available in August 2014. The announcement was significant because it signaled the beginning of a continuing partnership between IBM and Nvidia to develop GPU-accelerated IBM server systems, beginning with the Tesla K40 GPU.
The result was an HPC “tag-team” where IBM’s Power8 architecture, a 12-core chip with 96MB of embedded memory, would eventually go on to power Nvidia’s next-generation Pascal architecture which debuted in April 2016 at the company’s GPU Technology Conference.
NVLINK, first announced in March 2014, uses a proprietary High-Speed Signaling interconnect (NVHS) developed by Nvidia. The company says NVHS transmits data over a differential pair running at up to 20Gbps, so eight of these differential 20Gbps connections will form a 160Gbps “Sub-Link” that sends data in one direction. Two sub-links—one for each direction—will form a 320Gbps, or 40GB/s bi-directional “Link” that connects processors together in a mesh framework (GPU-to-GPU or GPU-to-CPU).
NVLINK lanes upgrade from 20Gbps to 25Gbps
IBM is projecting its Power9 servers to be available beginning in the middle of 2017, with PCWorld reporting that the new processor lineup will include support for NVLINK 2.0 technology. Each NVLINK lane will communicate at 25Gbps, up from 20Gbps in the first iteration. With eight differential lanes, this translates to a 400Gbps (50GB/s) bi-directional link between CPUs and GPUs, or about 25 percent more performance if the information is correct.
NVLINK 2.0 capable servers arriving next year
Meanwhile, Nvidia has yet to release any NVLINK 2.0-capable GPUs, but a company presentation slide in Korean language suggests that the technology will first appear in Volta GPUs which are also scheduled for release sometime next year. We were originally under the impression that the new GPU architecture would release in 2018, as per Nvidia’s roadmap. But a source hinted last month that Volta would be getting 16nm FinFET treatment and may show up in roughly the same timeframe as AMD’s HBM 2.0-powered Vega sometime in 2017. After all, it is easier for Nvidia to launch sooner if the new architecture is built on the same node as the Pascal lineup.
Still ahead of PCI-Express 4.0
Nvidia claims that PCI-Express 3.0 (32GB/s with x16 bandwidth) significantly limits a GPU’s ability to access a CPU’s memory system and is about “four to five times slower” than its proprietary standard. Even PCI-Express 4.0, releasing later in 2017, is limited to 64GB/s on a slot with x16 bandwidth.
To put this in perspective, Nvidia’s Tesla P100 Accelerator uses four 40GB/s NVLINK ports to connect clusters of GPUs and CPUs, for a total of 160GB/s of bandwidth.
With a generational NVLINK upgrade from 40GB/s to 50GB/s bi-directional links, the company could release a future Volta-based GPU with four 50GB/s NVLINK ports totaling of 200GB/s of bandwidth, well above and beyond the specifications of the new PCI-Express standard.
Notebook vendors have largely moved to on-board memory designs and are killing off DIMMs so that they can make their Intel Apollo Lake-based notebooks as slim as possible.
According to Digitimes shipments of Intel’s 14nm Apollo Lake CPUs, which feature low-power consumption, high performance and reduced sizes is apparently on the increase and with that a move to on board memory designs. The reason is that the manufactures think an anorexic look is super fashionable.
Numbers of new notebooks using LPDDR4 has also increased as vendors have continued to make efforts to minimize power consumption, improve performance, while prolonging battery life.
Acer has two new ultra-thin notebooks, the Aspire S 15 and S 17, both featuring a thickness of less than 17mm. Other vendors, including Lenovo, Asustek Computer, HP and Dell are also expected to focus on ultra-thin notebooks and 2-in-1 models for the second half of 2016, Digitimes said.
Fitbit Inc was cleared of stealing rival Jawbone’s trade secrets, a U.S. International Trade Commission judge ruled on Tuesday, ending Jawbone’s hopes of securing an import ban against Fitbit’s wearable fitness tracking devices.
The judge, Dee Lord, said that there had been no violation of the Tariff Act, which gives the commission the power to block products that infringe U.S. intellectual property, because “no party has been shown to have misappropriated any trade secret.”
The ruling means Jawbone comes away with nothing from a complaint it filed with the trade agency in July 2015, accusing Fitbit of infringing six patents and poaching employees who took with them confidential data about Jawbone’s business, such as plans, supply chains and technical details.
Two of the patents were withdrawn, however, and four others were invalidated by the judge, before a May trial that was limited to the trade secrets claims.
Fitbit Chief Executive Officer James Park said in a statement on Tuesday that Jawbone’s allegations were without merit and an attempt “to disrupt Fitbit’s momentum to compensate for their own lack of success in the market.”
A representative for Jawbone could not immediately be reached for comment.
Fitbit is biggest maker of wrist-based and clippable fitness devices, which track users’ steps, calories burned, heartrates and other parameters. It sold 5.7 million devices in the second quarter, beating revenue estimates.
Jawbone makes a range of activity trackers under the UP brand but has been losing market share. It is no longer among the top five wearables vendors, according to market research firm International Data Corp.
Tuesday’s ruling comes on the heels of a victory for Jawbone in a separate trade case filed against the company by Fitbit. On July 19, another commission judge found all three Fitbit patents in that case were invalid. Fitbit has asked the full trade commission to review the ruling.
Jawbone first sued Fitbit last year over trade secret violations in California state court, where the case is still pending. The companies, both based in San Francisco, are also litigating over patents in federal court.
Better-than-expected demand for Samsung Electronics Co Ltd’s new Galaxy Note 7 is creating supply problems worldwide, the South Korean tech giant said, suggesting strong initial sales for the new premium smartphone.
While robust demand could help deliver another solid quarter of earnings, Samsung also risks missing out on potential sales if it cannot boost supply quickly. Rivals such as Apple Inc are poised to launch new phones which could pull customers away from Samsung if a shortage persists.
“As pre-order results for the Galaxy Note 7 have far exceeded our estimates, its release date in some markets has been adjusted,” Samsung told Reuters in a statement without commenting on where launch delays could occur.
Production problems for the curved displays for the Galaxy S6 edge phone resulted in disappointing sales last year, and some investors fear a repeat if the world’s top smartphone maker does not move quickly to meet Note 7 demand.
Samsung said it was trying to boost production at the secret locations where the Notes are made, and aimed to meet demand “as early as possible”. It gave no further details.
A person familiar with the matter told Reuters there was no production issue for the curved screens used on the Galaxy Note 7 and that the shortage would not be a long-term problem.
“The party got more visitors than Samsung expected, so they just need to put more food out,” said Nomura analyst C.W. Chung, who said the supply situation was not a major risk given that Samsung made key parts such as displays and chips in-house.
Samsung could sell as many as 15 million Galaxy Note 7 phones this year, Chung said, compared with an estimated 9 million Galaxy Note 5 phones sold last year.
The phone went on sale on Aug. 19 in countries including the United States and South Korea, where it retails for 988,900 won ($882).
Software King of the World Microsoft has apparently been seen in public with the PC supremo Lenovo and insiders have been told that they want something more serious.
The pair have announced that they are deepening strategic ties but have not hinted about financial details. Instead Lenovo will load Microsoft’s productivity apps, including Microsoft Office, OneDrive and Skype on select Lenovo devices that use the Android operating system.
Microsoft did not say how much gear would be involved in the deal. Lenovo expects to ship millions of these Android-based devices worldwide over the next several years.
The deal is the latest in a string of similar deals by Microsoft with more than 70 Android device makers, including Samsung, HTC, Asus, Acer and Xiaomi.
The expanded collaboration between Microsoft and Lenovo also includes a patent cross-licensing agreement that covers Lenovo and Motorola devices.
Since Microsoft launched its IP licensing program in December 2003, it has entered into more than 1,200 licensing agreements.
Nick Parker, corporate vice-president OEM division, Microsoft said that Vole was thrilled that its productivity apps will be pre-installed on Lenovo’s premium devices and was talking about marrage.
“The marriage of Microsoft’s apps and Lenovo’s Android-based devices will enable customers worldwide to be more productive and connected and achieve even more,” he said.
Target will focus on its website, Target.com, and offline-online experiences such as order pickup and digital marketing, McNamara said in a blog post on the company’s website.
“Technology and supply chain are the new battlegrounds for retail,” he said. “The retailers with the strongest technology and supply chain will have the best chance of winning.”
Target will also focus on efforts such as store replenishment and merchandising systems to keep its stores well stocked, he said.
The retailer is in the middle of a hiring boom, McNamara said, adding that the company had hired about 700 engineers since he joined as CIO in February 2015.
Target had 341,000 employees as of Jan. 30, according to a regulatory filing.
The Z2 phone, equipped with a 4-inch screen and India-specific features such as a safety mode for motorcyclists, will be the cheapest Tizen phone Samsung has launched to date at 4,590 rupees ($68.44).
The phone, the first Tizen-powered device that will run on 4G networks, will start selling in India on Aug. 29.
The world’s top maker of smartphones, televisions and memory chips is trying to reduce its dependence on Google, whose Android operating system powers Samsung’s Galaxy smartphones.
The firm has been using Tizen on products ranging from TVs, home appliances and wearable products to enable the devices to communicate with each other and phones via the internet.
Samsung has so far kept Tizen for a small number of markets such as India and Bangladesh, where many potential customers are still first-time buyers looking for a cheap device and do not necessarily need a big library of apps.
The firm declined to comment on sales figures but analysts have said the Z2’s predecessors have found some success.
Fresh after scoring a reasonably sized contract for the iPhone, Intel is getting more excited about its mobile business and is talking about its 5G plans.
5G is a good thing to talk about as there is no standard yet and it could be years away before carriers think of moving to away from 4G. However, it does inspire confidence that companies, like Intel are busy researching it.
However the Intel Developer Forum (IDF),in San Francisco heard how Intel is not that interested in trying to create 5G modems for mobiles and will instead focus on the back-end infrastructure supporting the technology.
Intel said that while 5G will power the mobile internet, Intel believes there will be a lot of room for its processors and data centers to look after the millions of sensors, cars and internet of things devices which will all be part of it.
Intel said that 2G networks were about phones and voice, and it was rolling out 4G there were requirements that hadn’t been planned for when it was originally designed.
While 5G is expected to start appearing by 2020, it should support IoT devices, as well as broadcast-like services and lifeline communications. This means that the backbone of datacenters will need to be in place to make it go.
While Intel has been talking about this backbone, it does seem odd that it is not mentioned much about the modem front end of the technology. Our guess is that it is something that Intel cannot ignore and does not appear to be doing so, with its various Internet of Things gadgets.
Gartner’s figures for second-quarter smartphone growth were more optimistic than numbers reported by Strategy Analytics and Canalys recently. Both had reported modest growth of no more than 3% in smartphone shipments.
IDC last month reported second-quarter shipments were flat, growing just 0.3%.
Gartner’s numbers show that Apple’s iPhone sales dropped 7.7% in the second quarter, with 44.4 million phones sold globally, down from 48 million a year earlier. This decreased Apple’s market share to 12.9%, down from 14.6% a year earlier. Even so, Apple was second globally in smartphone sales.
Meanwhile, Samsung was the top smartphone seller, with 76.7 million smartphones sold, compared with 72 million sold a year earlier. That increase boosted its share to 22.3%, up from 21.8%.
Gartner said Samsung benefited by sales of the Galaxy A and Galaxy J series of smartphones which competed well against devices from Chinese smartphone makers.
Apple’s declines were the worst of any market in greater China and mature markets in Asia/Pacific, decreasing by 26%. There were also declines for Apple in North America and Western Europe, but there was a big jump of 95% in Eurasia, Sub-Saharan Africa and Eastern Europe.
Gartner ranked Huawei, Oppo and Xiaomi, in order, for third to fifth biggest in sales. Android devices were 86% of the total market, compared to 14.6% for iOS and 2.5% for Windows. Overall sales reached 344 million, up from 330 million a year earlier.
Massachusetts will begin levying a 5-cent fee per trip on ride-hailing apps such as Uber and Lyft and spend the money on the traditional taxi industry, a subsidy that appears to be the first of its kind in the United States.
Republican Governor Charlie Baker signed the nickel fee into law this month as part of a sweeping package of regulations for the industry.
Ride services are not enthusiastic about the fee.
“I don’t think we should be in the business of subsidizing potential competitors,” said Kirill Evdakov, the chief executive of Fasten, a ride service that launched in Boston last year and also operates in Austin, Texas.
Some taxi owners wanted the law to go further, perhaps banning the start-up competitors unless they meet the requirements taxis do, such as regular vehicle inspection by the police.
“They’ve been breaking the laws that are on the books, that we’ve been following for many years,” said Larry Meister, manager of the Boston area’s Independent Taxi Operator’s Association.
The law levies a 20-cent fee in all, with 5 cents for taxis, 10 cents going to cities and towns and the final 5 cents designated for a state transportation fund.
The fee may raise millions of dollars a year because Lyft and Uber alone have a combined 2.5 million rides per month in Massachusetts.
The law says the money will help taxi businesses to adopt “new technologies and advanced service, safety and operational capabilities” and to support workforce development.
Regulations for how the fee will be collected and a plan for how it will be spent still need to be drawn up, said Mark Sternman, a spokesman for the state’s MassDevelopment agency, which will be in charge of the money.
Riders and drivers will not see the fee because the law bars companies from charging them. Instead, companies themselves will pay the state, although Evdakov said it will be passed on to riders or drivers one way or another.
Authorities worldwide are grappling with how to regulate and tax ride-hailing. Seattle has passed a law that allows drivers to unionize. In Taiwan, Uber is battling a tax bill of up to $6.4 million.
Despite the cost, ride services in Massachusetts appear to have accepted the fee in exchange for other provisions. For example, the law does not ban them from picking up at Boston’s airport or convention center, although there will be special rules for those sites.
Lyft is pleased with the law even though it is not perfect, spokesman Adrian Durbin said.
Soliciting readers for how to spend the 5-cent fee, a column in the Boston Globe offered ideas such as hospitality training, incentive bonuses and help so taxi owners could buy “flagship” vehicles like a 1940s Checker or a Porsche.
Meister said the money could go toward improving a smartphone app his association has started using, or to other big needs.
“We definitely need some infrastructure changes,” he said.
Samsung Electronics Co Ltd is gearing up to launch a program to sell refurbished used versions of its premium smartphones as early as next year, a person with direct knowledge of the matter told Reuters.
The South Korean technology firm is looking for ways to sustain earnings momentum after reviving its mobile profits by restructuring its product line-up. As growth in the global smartphone market hits a plateau, Samsung wants to maximize its cost efficiency and keep operating margins above 10 percent.
The world’s top smartphone maker will refurbish high-end phones returned to the company by users who signed up for one-year upgrade programs in markets such as South Korea and the United States.
Samsung would then re-sell these phones at a lower price, the person said, declining to be identified as the plan was not yet public.
The person declined to say how big a discount the refurbished phones would be sold at, which markets the phones would be sold in or how many refurbished devices Samsung could sell.
A Samsung spokeswoman said the company does not comment on speculation.
It was not clear to what extent the phones would be altered, but refurbished phones typically are fitted with parts such as a new casing or battery.
Rival Apple Inc’s iPhone has a re-sale value of around 69 percent of its original price after about one year from launch, while Samsung’s flagship Galaxy sells for 51 percent of the original price in the U.S. market, according to BNP Paribas.
Refurbished phones could help vendors such as Samsung boost their presence in emerging markets such as India, where high-end devices costing $800 or so are beyond most buyers.
Apple sells refurbished iPhones in a number of markets including the United States, but does not disclose sales figures. It is trying to sell such iPhones in India, where the average smartphone sells for less than $90.
Selling used phones could help Samsung fend off lower-cost Chinese rivals that have been eating into its market share, and free up some capital to invest elsewhere or boost marketing expenditure.
Deloitte says the used smartphone market will be worth more than $17 billion this year, with 120 million devices sold or traded in to manufacturers or carriers – around 8 percent of total smartphone sales. Some market experts expect the used market to grow fast as there are fewer technology breakthroughs.
“Some consumers may prefer to buy refurbished, used premium models in lieu of new budget brands, possibly cannibalizing sales of new devices from those budget manufacturers,” Deloitte said in a report.
AT&T Inc, Google parent Alphabet Inc, Apple Inc, Verizon Communications Inc and Comcast Corp are among members of the “Robocall Strike Force” that held its first meeting with the U.S. Federal Communications Commission.
The strike force will report to the FCC by Oct. 19 on “concrete plans to accelerate the development and adoption of new tools and solutions,” said AT&T Chief Executive Officer Randall Stephenson, chairman of the group.
The strike force hopes to implement Caller ID verification standards to help block calls from spoofed phone numbers and consider a “Do Not Originate” list that would block spoofers from impersonating legitimate phone numbers from governments, banks or others.
FCC Chairman Tom Wheeler in July urged major companies to take new action to block robocalls, which often come from telemarketers or scam artists.
“This scourge must stop,” Wheeler said on Friday, calling robocalls the No. 1 complaint from consumers.
“The bad guys are beating the good guys with technology,” Wheeler said. In the past, he has said robocalls continue “due in large part to industry inaction.”
Stephenson emphasized “the breadth and complexity” of the problem.
“This is going to require more than individual company initiatives and one-off blocking apps,” Stephenson said. “Robocallers are a formidable adversary, notoriously hard to stop.”
The FCC does not require robocall blocking and filtering but has strongly encouraged phone service providers to offer those services at no charge.
The strike force brings together carriers, device makers, operating system developers, network designers and the government.
Other companies taking part include Blackberry Ltd, British Telecommunications Plc, Charter Communications Inc, Frontier Communications, LG Electronics Inc, Microsoft Corp, Nokia Corp, Qualcomm Inc, Samsung Electronics Co Ltd, Sirius XM Holdings Inc, T-Mobile US Inc and U.S. Cellular Corp.
Consumers Union, a public advocacy group, said the task force is a sign “phone companies are taking more serious steps to protect their customers from unwanted calls.”
Security researchers from Bitdefender have found an IoT smart electrical socket which leaks your Wi-Fi password, your email credentials and is so poorly coded that attackers can use it to hijack the device and use it for DDoS attacks. In the good old days all the power point could do was turn electrical equipment on and off.
Bitdefender didn’t reveal the device’s manufacturer but said the company is working on a fix, which will release in late Q3 2016.
Smart electrical sockets are small electrical socket extenders, which you can plug into a regular wall socket. In this case the device comes with a module that allows users to manage power consumption using predetermined limits and schedule the socket to allow usage only between certain hours.
Bitdefender said that there were several major problems with this unnamed smart socket. When users set up the product, they also need to install one of the accompanying iOS or Android apps. These apps allow the user to connect to the smart electrical socket’s built-in hotspot and configure it by entering the local Wi-Fi network credentials.
The IoT socket uses these credentials to connect to the local network, and contact the vendor servers, where it sends a configuration file that includes several device details, such as model, make, device name, firmware version, MAC address, and others
All this networking is done without encryption, in cleartext, which an attacker can easily pick-up if sniffing the local network at the right time.
Additionally, the device’s default admin username and password is easy to guess, even without reading the device documentation.
The device also comes with a built-in feature to send users email notifications when a device scheduled task executes successfully. For this feature to function properly, users must fill in their email account username and password in the device’s configuration panel. The device improperly stores these details.
Bitdefender researchers say that an attacker that knows the device’s MAC address and default password can take control over the device, rescheduling it, or access data on the user’s email account and password.
Only ten percent of people respond to and deal with desktop security alerts immediately, suggesting that the rest of the population simply ignores them or just lets it happen automatically.
You know the sort of warning. It might be Chrome telling you that something is untrusted, something like that. They are very easy to become blind to, like cookie warnings for example, and the study, which comes from Brigham Young University (BYU) and Google engineers, said that most people just ignore them.
The study, entitled More Harm Than Good? How Messages That Interrupt Can Make Us Vulnerable, suggests that this seeming neglect is down to the fact that people can only do so many things at once.
“System-generated alerts are ubiquitous in personal computing and, with the proliferation of mobile devices, daily activity. While these interruptions provide timely information, research shows they come at a high cost in terms of increased stress and decreased productivity,” the study said.
“This is due to dual-task interference, a cognitive limitation in which even simple tasks cannot be simultaneously performed without significant performance loss.”
Multitasking, then. People struggle to comprehend alerts because they are busy closing windows, stopping videos, typing or uploading at their desk or while mobile. Some 87 per cent showed the most disregard when “transferring information”.
The researchers explained things better in an interview with Phys.org. “We found that the brain can’t handle multitasking very well,” said co-author and BYU information systems professor Anthony Vance.
“Software developers categorically present these messages without any regard to what the user is doing. They interrupt us constantly and our research shows there’s a high penalty that comes by presenting these messages at random times.”
A better time to alert, according to the researchers, is at more passive times, for example while punters are waiting for a page to load or have finished watching a video.
“Waiting to display a warning when people are not busy doing something else increases their security behaviour substantially,” said Jeff Jenkins, lead author of the study.
Apple is trying to convince the world it is “coming up with something new” by talking a lot about Artificial Reality.
It is a fairly logical development, the company has operated a reality distortion field to create an alternative universe where its products are new and revolutionary and light years ahead of everyone else’s. It will be curious to see how Apple integrates its reality with the real world, given that it is having a problem with that.
Apple CEO Tim Cook has been doing his best to convince the world that Apple really is working on something. He needs to do this as the iPhone cash cow starts to dry up and Jobs Mob appears to have no products to replace it.
In an interview with The Washington Post published Sunday, Cook said Apple is “doing a lot of things” with augmented reality (AR), the technology that puts digital images on top of the real world.
“I think AR is extremely interesting and sort of a core technology. So, yes, it’s something we’re doing a lot of things on behind that curtain we talked about.”
However Apple is light years behind working being done by Microsoft with its Microsoft’s HoloLens headset and the startup Magic Leap’s so-called cinematic reality that’s being developed now.
Cook appears to retreat to AR whenever he is under pressure. But so far he has never actually said that the company is developing any.
Appple has also snapped up several companies and experts in the AR space. And in January, the Financial Times claimed that the company has a division of hundreds of people researching the technology.
But AR would be a hard fit to get a product out which fits Apple’s ethos and certainly not one for years. Meanwhile it is unlikely we will see anything new before Microsoft and Google get their products out.
