nVidia NVLINK 2.0 Going In IBM Servers
Comments Off on nVidia NVLINK 2.0 Going In IBM Servers
On Monday, PCWorld reported that the first servers expected to use Nvidia’s second-generation NVLINK 2.0 technology will be arriving sometime next year using IBM’s upcoming Power9 chip family.
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.

IBM Goes Bare Metal
IBM has announced the availability of OpenPower servers as part of the firm’s SoftLayer bare metal cloud offering.
OpenPower, a collaborative foundation run by IBM in conjunction with Google and Nvidia, offers a more open approach to IBM’s Power architecture, and a more liberal licence for the code, in return for shared wisdom from member organisations.
Working in conjunction with Tyan and Mellanox Technologies, both partners in the foundation, the bare metal servers are designed to help organisations easily and quickly extend infrastructure in a customized manner.
“The new OpenPower-based bare metal servers make it easy for users to take advantage of one of the industry’s most powerful and open server architectures,” said Sonny Fulkerson, CIO at SoftLayer.
“The offering allows SoftLayer to deliver a higher level of performance, predictability and dependability not always possible in virtualised cloud environments.”
Initially, servers will run Linux applications and will be based on the IBM Power8 architecture in the same mold as IBM Power system servers.
This will later expand to the Power ecosystem and then to independent software vendors that support Linux on Power application development, and are migrating applications from x86 to the Power architecture.
OpenPower servers are based on open source technology that extends right down to the silicon level, and can allow highly customised servers ranging from physical to cloud, or even hybrid.
Power systems are already installed in SoftLayer’s Dallas data centre, and there are plans to expand to data centres throughout the world. The system was first rolled out in 2014 as part of the Watson portfolio.
Prices will be announced when general availability arrives in the second quarter.
IBM And Tencent Team Up
Tencent Holdings Ltd announced that it would be teaming up with International Business Machines Corp (IBM) on a new cloud software business for corporate customers, a marked departure for one of the dominant forces in China’s consumer Internet industry.
Best known for its popular WeChat messaging app and its online games rather than business software, Tencent said its cloud unit would now target small and medium enterprises in the healthcare and “smart city” industries.
Many technology firms are jockeying for a slice of China’s enterprise software market, which promises to grow sharply in coming years as businesses modernize their IT operations and move data onto the cloud.
Tencent’s alliance with IBM, which has deep experience providing computing and consulting services to corporate clients, provides the Shenzhen company a competitive answer to its Chinese rival Alibaba Group Holding Ltd’s nascent cloud efforts.
An e-commerce giant, Alibaba has been slowly building its cloud unit, which recorded just $38 million in revenue in the three months ended June 30.
Tencent said it would tap IBM for its “industry expertise and enterprise reach” but did not disclose financial terms of the deal.
For IBM, the Tencent deal is just the latest in a recent spate of new software partnerships in China, where its hardware sales have been sliding.
IBM announced a deal earlier this year to install its cutting-edge DB2 database software on Chinese rival Inspur International Ltd’s machines. Big Blue also agreed to license its database and big data technology to Chinese software vendor Yonyou Software Co Ltd.
Will IBM Realize Growth In 2015?
International Business Machines Corp said it is projecting growth in its hardware sector next year as the company invests in research and development and abandons low-performing ventures.
The comments come less than one month after the world’s largest technology service company reported its lowest quarterly revenue in five years, weighed by sluggish global demand for its hardware, which plunged 23 percent in the first quarter of 2014.
The company added that growth in Latin America, the Middle East and Africa remain strong, and blamed falling revenue in China on government reforms affecting state-owned clients, and on the country’s hardware-heavy portfolio.
“We move on and we spread ourselves out, more industries, more clients, cloud, data, et cetera, around there,” said IBM Chief Executive Ginni Rometty at an investor briefing on Wednesday.
Chief Financial Officer Martin Schroeter said to stabilize the hardware sector IBM would continue to “refresh” hardware and further invest in research and development.
“Quite frankly, we are seeing very good growth out of software, good growth out of services, but challenges in hardware,” said Schroeter. “We will stabilize that hardware base and I am comfortable we will make that happen in 2014,” he said.
He reiterated the company’s EPS target for 2015 of at least $20. He expects a shift to higher-value business to bring in $3.25 and share repurchases to add $2 in earnings per share by 2015.
HP’s Z-station Goes Nvidia
HP has added its Z Workstation family with a solution that delivers access via a virtual desktop route to workstation applications hosted in the data center.
Set to be available from next month, the HP DL380z Virtual Workstation enables organisations to provide remote access to workstation-class applications, even those calling for heavy-duty graphics, which allows them to keep data stored securely in the data centre wherever employees might be based.
As its name suggests, the HP DL380z is based on the same hardware as HP’s ProLiant DL380p server, a 2U rack-mount two-socket system based on Intel’s Xeon E5-2600 processors, which allows it to slot right into existing data centre infrastructure.
Where the HP DL380z differs is that it can be configured with up to two Nvidia Grid K2 graphics cards supporting the graphics firm’s Grid GPU virtualisation technology. This enables up to eight users to be hosted on each system, each with access to a virtual machine with GPU acceleration capabilities.
Jeff Groudan, worldwide director for HP Thin Client and Virtual Workstations, said, “For employees who work from A to B and everywhere in between, the HP DL380z allows them to access data that is securely stored in the data centre. Furthermore, the powerful HP DL380z is an always-on workhorse that can be used by businesses when not in use for virtual workstation sessions.
Remote access is delivered either by operating Citrix’s XenServer with its HDX 3D Pro technology, which the HP DL380z is certified for, or by utilising HP’s own Remote Graphics Software (RGS). The latest HP RGS release 7 adds the ability to have true workstation productivity from a tablet while bringing intuitive touch controls to non-touch applications, according to HP.
Either way, customers can provide engineers or other professional users with access to workstation-class applications from a variety of devices, including thin clients, laptops or tablets.
Pricing for the HP DL380z has yet to be confirmed.
HP & Foxcomm Head To The Cloud

Comments Off on HP & Foxcomm Head To The Cloud
HP and Foxcomm have announced a joint venture to create a line of cloud optimized servers for service providers.
The venture involving a non-equity, strategic commercial alliance will see the pair offering a range of products. Particulars and specifications are yet to be announced but the companies are aiming to target low total cost of ownership (TCO), scale and service.
This announcement is separate to the existing HP Proliant server portfolio, which includes the software defined server codenamed Moonshot.
HP CEO Meg Whitman said, “With the relentless demands for compute capabilities, customers and partners are rapidly moving to a New Style of IT that requires focused, scalable and high-volume system designs. [The partnership] will enable us to deliver a game-changing offering in infrastructure economics.”
News of the alliance will raise eyebrows at Apple, which reportedly returned an eight million unit shipment of iPhones to Foxconn last year, describing them as “dysfunctional” and “non-compliant”.
HP has had its own troubles recently, after settling two lawsuits this month, one to the former shareholders of Palm over its handling of WebOS, and another that revealed that HP executives were guilty of corruption in negotiations for lucrative contracts. Total payouts across the two settlements totaled $165m.
The HP joint venture with Foxconn will take effect from 1 May, when we hope to find out more details about what it will entail.
App Stores For Supercomputers Enroute
Comments Off on App Stores For Supercomputers Enroute
A major problem facing supercomputing is that the firms that could benefit most from the technology, aren’t using it. It is a dilemma.
Supercomputer-based visualization and simulation tools could allow a company to create, test and prototype products in virtual environments. Couple this virtualization capability with a 3-D printer, and a company would revolutionize its manufacturing.
But licensing fees for the software needed to simulate wind tunnels, ovens, welds and other processes are expensive, and the tools require large multicore systems and skilled engineers to use them.
One possible solution: taking an HPC process and converting it into an app.
This is how it might work: A manufacturer designing a part to reduce drag on an 18-wheel truck could upload a CAD file, plug in some parameters, hit start and let it use 128 cores of the Ohio Supercomputer Center’s (OSC) 8,500 core system. The cost would likely be anywhere from $200 to $500 for a 6,000 CPU hour run, or about 48 hours, to simulate the process and package the results up in a report.
Testing that 18-wheeler in a physical wind tunnel could cost as much $100,000.
Alan Chalker, the director of the OSC’s AweSim program, uses that example to explain what his organization is trying to do. The new group has some $6.5 million from government and private groups, including consumer products giant Procter & Gamble, to find ways to bring HPC to manufacturers via an app store.
The app store is slated to open at the end of the first quarter of next year, with one app and several tools that have been ported for the Web. The plan is to eventually spin-off AweSim into a private firm, and populate the app store with thousands of apps.
Tom Lange, director of modeling and simulation in P&G’s corporate R&D group, said he hopes that AweSim’s tools will be used for the company’s supply chain.
The software industry model is based on selling licenses, which for an HPC application can cost $50,000 a year, said Lange. That price is well out of the reach of small manufacturers interested in fixing just one problem. “What they really want is an app,” he said.
Lange said P&G has worked with supply chain partners on HPC issues, but it can be difficult because of the complexities of the relationship.
“The small supplier doesn’t want to be beholden to P&G,” said Lange. “They have an independent business and they want to be independent and they should be.”
That’s one of the reasons he likes AweSim.
AweSim will use some open source HPC tools in its apps, and are also working on agreements with major HPC software vendors to make parts of their tools available through an app.
Chalker said software vendors are interested in working with AweSim because it’s a way to get to a market that’s inaccessible today. The vendors could get some licensing fees for an app and a potential customer for larger, more expensive apps in the future.
AweSim is an outgrowth of the Blue Collar Computing initiative that started at OSC in the mid-2000s with goals similar to AweSim’s. But that program required that users purchase a lot of costly consulting work. The app store’s approach is to minimize cost, and the need for consulting help, as much as possible.
Chalker has a half dozen apps already built, including one used in the truck example. The OSC is building a software development kit to make it possible for others to build them as well. One goal is to eventually enable other supercomputing centers to provide compute capacity for the apps.
AweSim will charge users a fixed rate for CPUs, covering just the costs, and will provide consulting expertise where it is needed. Consulting fees may raise the bill for users, but Chalker said it usually wouldn’t be more than a few thousand dollars, a lot less than hiring a full-time computer scientist.
The AweSim team expects that many app users, a mechanical engineer for instance, will know enough to work with an app without the help of a computational fluid dynamics expert.
Lange says that manufacturers understand that producing domestically rather than overseas requires making products better, being innovative and not wasting resources. “You have to be committed to innovate what you make, and you have to commit to innovating how you make it,” said Lange, who sees HPC as a path to get there.
Xerox Moving Into IT Services
Printer and copier maker Xerox Corp forecast current-quarter earnings below estimates as it quickens efforts to transform itself into a technology services provider.
Xerox, whose shares were little changed at midday, also offers services such as managing toll systems and healthcare programs to counter sluggish growth in its printers and copiers business, which accounts for about 40 percent of its revenue.
Services is now the larger part of the company’s business and lower margins in IT and business process outsourcing is dragging overall margins.
The company said it expects second-quarter revenue from its document technology business, which includes printers and copiers, to decline in the mid-single digits. Revenue fell 9 percent to $2.14 billion in the business in the first quarter.
Based in Norwalk, Connecticut, Xerox moved into business services with its purchase of Affiliated Computer Services Inc (ACS) for $5.5 billion in 2009 – the company’s biggest deal in its 106-year history.
Xerox said it plans to quicken the pace of a restructuring plan kicked off in the last quarter of 2012 and included a 2-cent restructuring charge in its second-quarter forecast.
Xerox said it expects flattish revenue for the full year, compared with previous expectations of up to a 2 percent growth, it said on a conference call with analysts.
The company said it was on track to reach its target of adjusted EPS of $1.09 to $1.15 for the full year and to generate operating cash flow of $2.1 billion to $2.4 billion.
“Europe remains weak. US remains stable, but weak. We have not seen a pickup in the US,” Xerox CEO Ursula Burns said on a conference call with analysts.
“We did see a slowdown, a bit of a slowdown, in some developing market economies. But our business model is fairly resilient in the developing markets,” she said.
Mozilla Touts WebRTC
Mozilla has shown off WebRTC integration in its Firefox web browser, demonstrating real-time video conferencing and file transfer capabilities.
All major web browser developers have started to integrate the WebRTC protocol and now Mozilla has shown off how far its integration has come. The firm demonstrated working video conferencing, file transfer and sharing capabilities through the Firefox web browser.
Mozilla was keen to push its implementation of the Datachannels API that is part of WebRTC to allow instant messaging and file transfer. The firm’s impressive demonstration shows off seamless sharing between two clients that had initiated a video conversation, with tabs and files being sent and viewed with little user interaction.
Mozilla’s demonstration does highlight the need for tight sandboxing within the web browser, however as a peer-to-peer protocol that automatically encrypts communications between two hosts, WebRTC could challenge some existing closed communication protocols such as Skype.
Maire Reavy, product lead for Firefox Platform Media at Mozilla said, “WebRTC is a powerful new tool that enables web app developers to include real-time video calling and data sharing capabilities in their products. While many of us are excited about WebRTC because it will enable several cool gaming applications and improve the performance and availability of video conferencing apps, WebRTC is proving to be a great tool for social apps.”
Mozilla didn’t say when its WebRTC implementation will enter the stable release channel, however given the outfit’s rapid release schedule, it should be a matter of weeks rather than months.
Amazon Goes To Court
Amazon is suing Daniel Powers, its ex VP in charge of global sales for Amazon Web Services because he joined Google in a cloud role.
Taking the new job, asserts Amazon, violates Powers’ non-compete agreement with Amazon, which let Powers go this summer with a reasonable severance package.
There is a risk that Powers could take important information that he learned about the Amazon web services business to its rival, Google, and that is what the firm is seeking to stop.
According to Geekwire Amazon wants an injunction against Powers to prevent him from “engaging in any activities that directly or indirectly support any aspect of Google’s cloud computing business”.
A court filing claims that Amazon has an agreement with Powers that says he will not join a rival for a “limited time following the termination of his employment”.
Powers, it warns, is a veteran who knows the cloud business from “top to bottom”, adding that he has “acquired and currently possesses extensive knowledge of Amazon’s trade secrets and its highly confidential information”.
The complaint says that he has extensive and detailed information about Amazon Web Services’ prospects, business, potential business partners, pricing strategies and goals.
