Nvidia gets broad support for cutting-edge Volta GPUs in the data center

Data center workloads for AI, graphics rendering, high-performance computing and business intelligence are getting a boost as a Who's Who of the world's biggest server makers and cloud providers snap up Nvidia's Volta-based Tesla V100 GPU accelerators.Nvidia is rallying its entire ecosystem, including software makers, around the new Tesla V100s, effectively consolidating its dominance in GPUs for data centers.IBM, HPE, Dell EMC and Supermicro announced at the Strata Data Conference in New York Wednesday that they are or will be using the GPUs, which are now shipping. Earlier this week at Nvidia's GPU Technology Conference in Beijing, Lenovo, Huawei and Inspur said they would be using Nvidia's HGX reference architecture to offer Volta architecture-based systems for hyperscale data centers.To read this article in full or to leave a comment, please click here

BrandPost: Four Ways To Bridge The Digital Talent Gap

Rapid technological development not only fuels business innovation, but also disrupts traditional business models. In order to keep pace with the latest technology trends, businesses must employ the right professionals who combine technology expertise with business acumen. Unfortunately, corporations often lack this kind of talent to help make the right technology decisions and avoid costly and potentially disastrous mistakes. According to the Global Knowledge 2017 IT Skills and Salary Report, there are significant skills shortages in key ICT sectors, such as, security and cloud computing. These findings highlight the difficulties that recruiters face in times where the demand for ICT talent far exceeds the supply. Scouting, recruiting and retaining talent in such a competitive environment is a challenge; however, the criticality of it calls for a contingency plan to build a pipeline of professionals that can boost the future of businesses and the economy in the digital age.To read this article in full or to leave a comment, please click here

Can IoT platforms from Apple, Google and Samsung make home automation systems more secure?

In August 2017, a new botnet called WireX appeared and began causing damage by launching significant DDoS attacks. The botnet counted tens of thousands of nodes, most of which appeared to be hacked Android mobile devices.

There are a few important aspects of this story.

First, tracking the botnet down and mitigating its activities was part of a wide collaborative effort by several tech companies. Researchers from Akamai, Cloudflare, Flashpoint, Google, Oracle Dyn, RiskIQ, Team Cymru, and other organizations cooperated to combat this botnet. This is a great example of Collaborative Security in practice.

Second, while researchers shared the data, analysed the signatures, and were able to track a set of malware apps, Google played an important role in cleaning them up from the Play Store and infected devices.

Its Verify Apps is a cloud-based service that proactively checks every application prior to install to determine if the application is potentially harmful, and subsequently rechecks devices regularly to help ensure they’re safe. Verify Apps checks more than 6 billion instances of installed applications and scans around 400 million devices per day.

In the case of WireX, the apps had previously passed the checks. But thanks to the researcher’s findings, Google Continue reading

Out of the Section 230 Weeds: Internet Publisher-Providers

On Tuesday, the U.S. Congress continued to grapple with the potential implications of the Stop Enabling Sex Traffickers Act (SESTA). SESTA would carve out an exception to Section 230 of the 1996 Communications Decency Act, which is considered a bedrock upon which the modern Internet has flourished. If SESTA became law, websites that host ads for sex with children would be not be immune from state prosecutions and private lawsuits [although under 320(c)(1), websites are already subject to federal criminal law statutes].

Section 230 of the Communications Decency Act (c)(1) states, “No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” 230(c)(2) protects actors who proactively block and screen for offensive material. These provisions have allowed the Internet to grow and develop without the threat of lawsuits smothering its potential. If the websites of 1990 had been liable for everything their users posted, the Internet would look very different today.

Since 1996, the Internet has dramatically changed in ways unanticipated by the Communications Decency Act. The Internet provides the platform to publish material that can reach enormous numbers of people around Continue reading

When disasters strike, edge computing must kick in

Edge computing and fog networks must be programmed to kick in when the internet fails during disasters, a scientific research team says. That way, emergency managers can draw on impacted civilians’ location data, social networking images and tweets and use them to gain situational awareness of scenes.Routers, mobile phones and other devices should continue to collect social sensor data during these events, but instead of first attempting to send it through to traditional cloud-based depositories operated by the social network — which are unavailable due to the outage — the geo-distributed devices should divert the data to local edge computing, fog nodes and other hardened resources. Emergency officials can then access it.To read this article in full or to leave a comment, please click here

IDG Contributor Network: 4G LTE internet is a network-saver

4G LTE Internet is an under-utilized asset for your company’s network… and your sanity.As someone who’s owned a business telecom, Internet, and cloud brokerage for 14 years [shameless plug], I’ve had my share of drama surrounding circuits taking too long to install. Whether it’s fiber taking a year to get built-out, or a T1 taking 6 weeks to install (when our customer’s business was relocating in 4), being at the mercy of an ISP’s unexplainable, bureaucratic timeline has been the most stressful part of my job.To read this article in full or to leave a comment, please click here

Real-time visibility and control of campus networks

Many of the examples on this blog describe network visibility driven control of data center networks. However, campus networks face many similar challenges and the availability of industry standard sFlow telemetry and RESTful control APIs in campus switches make it possible to apply feedback control.

HPE Aruba has an extensive selection of campus switches that combine programmatic control via a REST API with hardware sFlow support:
  • Aruba 2530 
  • Aruba 2540 
  • Aruba 2620
  • Aruba 2930F
  • Aruba 2930M
  • Aruba 3810
  • Aruba 5400R
  • Aruba 8400
 This article presents an example of implementing quota controls using HPE Aruba switches.
Typically, a small number of hosts are responsible for the majority of traffic on the network: identifying those hosts, and applying controls to their traffic to prevent them from unfairly dominating, ensures fair access to all users.

Peer-to-peer protocols (P2P) pose some unique challenges:
  • P2P protocols make use of very large numbers of connections in order to quickly transfer data. The large number of connections allows a P2P user to obtain a disproportionate amount of network bandwidth; even a small number of P2P users (less than 0.5% of users) can consume over 90% of the network bandwidth.
  • P2P protocols (and users) are very good Continue reading

Nvidia accelerates the path to AI for IoT, hyperscale data centers

It’s safe to say the Internet of Things (IoT) era has arrived, as we live in a world where things are being connected at pace never seen before. Cars, video cameras, parking meters, building facilities and anything else one can think of are being connected to the internet, generating massive quantities of data.The question is how does one interpret the data and understand what it means? Clearly trying to process this much data manually doesn’t work, which is why most of the web-scale companies have embraced artificial intelligence (AI) as a way to create new services that can leverage the data. This includes speech recognition, natural language processing, real-time translation, predictive services and contextual recommendations. Every major cloud provider and many large enterprises have AI initiatives underway.To read this article in full or to leave a comment, please click here
