Nvidia’s DGX-1 supercomputer packs the horsepower of 250 servers

Your electric bills could soar if you kept Nvidia's monster DGX-1 computer running continuously for one month. The DGX-1 supercomputer can deliver the computing power of 250 two-socket servers in a desktop box, claimed Nvidia, which introduced the system Tuesday at its GPU Technology Conference in San Jose, California. The computer can deliver about 170 teraflops of performance, and multiple boxes on a rack could deliver 2 petaflops of performance. The fastest computer in the world delivers a peak performance of about 10 petaflops. Nvidia says DGX-1 is about 56 times faster than a server with two Intel Xeon-E5 2697 v3 chips, which can deliver about 3 teraflops of performance.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Banks are failing to capitalize on Big Data, says financial IT expert

Banks are neglecting to analyze the highly useful data being generated by new kinds of consumer-facing products, like apps, says an expert in the financial IT sector.Many financial institutions are overlooking key intelligence and indicators that they could be taking advantage of to re-invent themselves and ultimately compete with future disruption, thinks Deanne Yamato-Tucker, who heads Xavient Information Systems’ banking and financial services practice. Banking disruption could include peer-to-peer, blockchain and services like Bitcoin, for example.“Banks need to address the threat from new entrants such as PayPal, Google, Amazon, Apple, and P2P FX,” Yamato-Tucker told me in an e-mail. But they’re not managing their data properly to do so, she thinks.To read this article in full or to leave a comment, please click here

Reaction: The 650 Gb/s software router

I’m forever seeing announcements like this in the software defined networking world—

The Linux-based CloudRouter Project, which is working on code for an open source virtual router, released version 3.0 this week. It adds Linux Data Plane Development Kit (DPDK) kernel enhancements and claims throughput in excess of 650 Gb/s on commodity hardware.

But you need to note one specific thing about this announcement. How did they achieve these forwarding rates? By using DPDK to offload the actual, well, forwarding to a custom ASIC on a NIC. The reality is that we’ve always done the control plane in software, and we’ve always done the forwarding in hardware. There have been precious few router platforms over the years where the forwarding plane is actually an “embedded system.”

Certainly we’re seeing a world where open source operating systems are learning to interact with commodity ASICs so it’s possible to separate the software from the hardware, and the operating system from the control plane, and this is all too the good. But if this is software defined networking, then we’ve been doing this since sometime in the 1990’s, perhaps even earlier…

Perhaps we’ve become so accustomed to considering the network operating Continue reading

Three-year-old IBM patch for critical Java flaw is broken

Security researchers have found that a patch released by IBM three years ago for a critical vulnerability in its own Java implementation is ineffective and can be easily bypassed to exploit the flaw again.The broken patch was discovered by researchers from Polish firm Security Explorations who found the vulnerability and reported it to IBM in May 2013. IBM issued a fix in a July 2013 update for its Java development kit.IBM maintains its own implementation of the Java virtual machine and runtime. This version of Java is included in some of the company's enterprise software products, as well as in the IBM Software Developer Kit, which is available for platforms like AIX, Linux, z/OS and IBM i.To read this article in full or to leave a comment, please click here

Feds lack managed response to large-scale cyber attack

The Department of Defense is unclear about who would take charge and work with civilian authorities during a large-scale cyber attack on the US.There are a number of plans and directions for how the government would respond to a cyber attack on the nation’s electric grid or other large entity but tons of clarification and specific directions need to be ironed out to respond effectively, according to a Government Accountability Office report out this week.+More on Network World: IRS: Top 10 2015 identity theft busts+To read this article in full or to leave a comment, please click here

UL takes on cybersecurity testing and certification

Underwriters Laboratories (UL) today announced a new Cybersecurity Assurance Program (CAP) that uses a new set of standards to test network-connected products for software vulnerabilities.The new UL certification will be for both vendors of Internet of Things (IoT) products and for buyers of products who want to mitigate risks.The testing standards were developed as part of a voluntary program involving industry officials as well as academics and the U.S. government.INSIDER: 5 ways to prepare for Internet of Things security threats President Obama's broad Cybersecurity National Action Plan, released in February, details a long-term strategy to improve cybersecurity awareness and protections. Obama's plan specifically notes that UL worked with the Department of Homeland Security to develop CAP to test and certify networked devices "whether they be refrigerators or medical infusion pumps, so that when you buy a new product, you can be sure it has been certified to meet security standards."To read this article in full or to leave a comment, please click here

IoT tech goes from planning stage to execution

Internet of Things technologies can be complex and fragmented, but increasing numbers of pilot projects are emerging within smart cities, farms and at a wide range of businesses and industries."We are seeing adoption of IoT begin," said Mark Bartolomeo, vice president of IoT at Verizon, in an interview. "There are now use cases for IoT and less of an industry focus on the technology. The biggest macro trend lately is how IT can use the data [from IoT] more effectively to run a better business for customers."The carrier launched its ThingSpace development platform last October for companies to create and manage IoT applications more efficiently. In February, Verizon announced it had more than 4,000 developers using ThingSpace, and would open the software to third-party network and tech providers.To read this article in full or to leave a comment, please click here

IDG Contributor Network: The past and future of the videoconference room, Part 3: The User Interface

In the first of this series of blogs, I discussed the history and future of videoconferencing cameras, in the second I discussed the hierarchy of rooms/spaces/environments for visual collaboration. This – part three – is about how to use the darned things.From the earliest days of technology in enterprise conference rooms the user interface (UI) has been a contentious, problematic and difficult part of users’ satisfaction with that technology. All UIs have to achieve a balance between simplicity and power. The more that they can do, the harder they are to operate. So because videoconferencing has traditionally been hard, the UI has needed to do a lot to meet the needs.To read this article in full or to leave a comment, please click here

What’s the deal with the massive Panama Papers data leak?

A data breach at Panamanian law firm Mossack Fonseca is being touted as the largest ever, at least in terms of the sheer volume of information leaked. The leaked information allegedly details the ways dozens of high-ranking politicians, their relatives or close associates in more than 40 countries, including the U.K., France, Russia, China, and India, have used offshore companies to hide income and avoid paying taxes. Starting on Sunday, more than 100 news organizations filed reports based on the leaked information. The numbers: The leaks reportedly cover 11.5 million confidential documents dating from the 1970s through late 2015. The 2.6 terabytes of leaked data include 4.8 million emails, 3 million database format files, 2.2 million PDFs, 1.1 million images, and 320,000 text documents.To read this article in full or to leave a comment, please click here

Google fixes 39 Android flaws, some allow hackers to take over your phone

Google has released one of the largest Android monthly security updates, fixing a total of 39 vulnerabilities — 15 rated critical, including four that can lead to a complete device compromise.The patches, which are included in new firmware images that were released Monday for the company's Nexus devices, will also be published to the Android Open Source Project over the next 24 hours.They include a fix for a vulnerability that Google warned about two weeks ago and which is already being exploited by a publicly available rooting application. Tracked as CVE-2015-1805, the privilege escalation flaw was originally fixed in the Linux kernel in April 2014, but it didn't become clear until February this year that it also affects Android.To read this article in full or to leave a comment, please click here

Why an Open Internet Matters

As an Internet Society board member coming from the Middle East, I’m often confronted by the question of whether it is enough to have Internet access, or must we also ensure that the access is open and unrestricted. I hereby lay the case in this short article in defense of the argument that having an open Internet does matter and we ought to ensure it remains so. -via the Internet Society

IDG Contributor Network: Will corporate sustainability save IT from itself?

Last week, flying out of SFO northward over the verdant hills of Marin, rising above the tankers anchored off Richmond swinging with the tide and the long plumes from the Sacramento River’s inflow to the bay like ribbons unfurling in the water, I reflected on a visit that touched five Silicon Valley sustainability stakeholders in two days. Enroute to my adopted home of Seattle, I am struck with the commonality of these sessions and an early release of Uptime Institute’s 2016 Industry Survey results. (Disclosure: I work for Uptime Institute and oversee the content group there.)There are new faces at the IT table. And one of them is sustainability. Two years ago, a place at the table for sustainability would have been provocative, and perhaps evoked derision. In 2015, less than a tenth of enterprise IT stakeholders had confidence in corporate sustainability to affect IT efficiency and costs. One short year later, 2016 is a vastly different matter and the data suggests that the time of corporate sustainability in IT is here now: 70% of enterprise IT organizations actively participate in corporate sustainability efforts. The influence of an outside party breaks down the ‘thwart by silo’ effect that Continue reading
