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.

The study, summarized on the Conversation site looked at the prevalence of mobile phones among the population against brain cancer rates, using data from national cancer registration.

The results showed a very slight increase in brain cancer rates among males, but a stable level among females. There were significant increases in over-70s, but this problem started before 1982.

The figures should have even been higher as Computed tomography (CT), magnetic resonance imaging (MRI) and related techniques, introduced in Australia in the late 1970s can spot brain tumors which could have otherwise remained undiagnosed.

The data matches up with other studies conducted in other countries, but in Australia all diagnosed cases of cancer have to be legally registered and this creates consistent data.

The argument that mobile phones cause cancer has been running ever since the phones first arrived. In fact the radiation levels on phones has dropped significantly over the years, just to be safe rather than sorry. However it looks like phones have had little impact on cancer statistics – at least in Australia.

T-Mobile has been offering cheaper leasing plans and free music and video streaming to lure customers away from larger rivals Verizon Communications Inc and AT&T Inc.

T-Mobile, controlled by Deutsche Telekom, said it added 2.2 million customers on a net basis in the first quarter ended March 31.

That easily topped the average analyst estimate of 1.72 million, according to research firm FactSet StreetAccount.

The company said it expected to add 3.2 million to 3.6 million postpaid customers on a net basis in 2016, compared with its previous forecast of 2.4 million to 3.4 million.

T-Mobile’s 10.6 percent jump in quarterly revenue to $8.6 billion suggested its strategy to boost revenue was working. Analysts on average had expected revenue of $8.43 billion, according to Thomson Reuters I/B/E/S.

In comparison, market leader Verizon’s operating revenue rose just 0.6 percent to $32.17 billion.

AT&T is scheduled to report results later on Tuesday.

T-Mobile reported net income of $479 million, or 56 cents per share, for the first quarter, compared with a loss of $63 million, or 9 cents per share, a year earlier.

The social network continues to see surging interest in video. During one day last quarter, its users watched a combined 100 million hours of video. Roughly 500 million users watch at least some video each day.

That’s a lot of video and a lot of viewers, and Facebook wants to capitalize on it.

“We are exploring a dedicated place on Facebook for when they just want to watch videos,” CEO Mark Zuckerberg said Wednesday during a conference call to discuss Facebook’s quarterly financial results.

But he was tight-lipped on how the video might actually be presented.

Asked if a stand-alone video app is in the cards, he mentioned the success of Messenger and a Facebook app for managing Pages. “I do think there are additional opportunities for this and we’ll continue looking at them,” he said.

Facebook wants to encourage more video viewing because it keeps users on the site longer, helping it to sell more ads.

“Marketers also really love video and it’s a compelling way to reach consumers,” COO Sheryl Sandberg said during the call.

Zuckerberg has been watching the growth of video for osme time. At a town hall meeting in November 2014, he predicted, ”In five years, most of [Facebook] will be video.”

And it’s likely that most of that video will be consumed over mobile networks.

Among Facebook’s heaviest users — the billion people who access it on a daily basis — 90 percent use a mobile device, either solely or in addition to their PC.

It’s financial results for the fourth quarter were strong. Revenue was $5.8 billion, up 52 percent from the same period in 2014, while net profit more than doubled to $1.6 billion.

PC manufacturers shipped 75.7 million machines in the fourth quarter compared with about 82.6 million a year earlier. Sales sank 3.1 per cent in the US to 16.9 million in the quarter.

Gartner forecasts a fall of  a  percent in 2016 with the potential of a soft recovery later in the year.

Mikako Kitagawa, an analyst at Gartner said that the  fourth quarter of 2015 marked the fifth consecutive quarter of worldwide PC shipment decline. Holiday sales did not boost the overall PC shipments, hinting at changes to consumers’ PC purchase behavior.

Lenovo retained its leadership of the PC market with 20 percent of the global market in the fourth quarter. Its shipments dropped 4.2 percent. HP was the  No. 2 global PC maker, increased its market share slightly to almost 19 percent. The company maintained its top position in the U.S., with 27 percent of the market, despite a decline of 8.4 percent in fourth-quarter shipments. Del increased its global market share to 13.5 percent from 13.1 percent and ranked third.

IDC released similar figures saying that it was all the fault of the strong US dollar hampered overseas sales. It thinks that the decline in PC sales may slow in 2016, with IDC projecting a fall of 3.1 percent compared with 10 percent drop in 2015. Greater commercial adoption of Microsoft Windows 10 operating system may help stabilize sales.

But after years of fantastic growth in smartphone sales, the pace of growth is slowing overall, including for the two smartphone giants. Market research firm IDC recently said that 2016 will be the first year that overall smartphone growth will slow to below 10%.

There is even talk among analysts that the latest models don’t have enough compelling new features to lure customers to a competitor’s device. Others say smartphone buyer’s fatigue has set in.

Buyer’s fatigue is a concern in the U.S. and other developed countries where the smartphone market is viewed as a “replacement” market because the market is already saturated: Nearly everyone already owns a smartphone. A focus on emerging countries by Apple and Samsung still requires them to find low-cost alternatives to compete with the likes of Huawei and others.

“Consumers are fatigued about new phone features that they can’t easily relate to any improvement in their personal use cases,” said Patrick Moorhead, an analyst at Moore Insights & Strategy. “Samsung has been one of the worst offenders of this in the last few years. If consumers can’t relate, then they need to be educated.”

Most recently, reports that Samsung would add a pressure-sensitive displayand high-speed charging port to its Galaxy S7 phone drew a few yawns. That’s because Apple added the pressure-sensitive display to the iPhone 6S last summer, and a new USB Type-C fast charging port is already available in LG and Huawei smartphones.

While it is to Samsung’s advantage to keep up with Apple and others rivals, analysts disagree over whether these latest improvements will provoke an iPhone user to switch to a Galaxy.
