Nvidia’s new Volta-based DGX-1 supercomputer puts 400 servers in a box

You won't need to buy a rack of 400 servers if you have one high-powered Nvidia DGX-1 supercomputer with a Volta GPU sitting on your desktop.The DGX-1 supercomputer -- which looks like a regular rack server -- gets most of its computing power from eight Tesla V100 GPUs.The GPU, the first one based on the brand-new Volta architecture, was introduced at the company's GPU Technology Conference in San Jose, California, on Wednesday."It comes out of the box, plug it in and go to work," said Nvidia's CEO Jen-Hsun Huang during a keynote speech.But the DGX-1 with Tesla V100 computer is expensive. At US$149,000, it's worth some people's life savings. But Huang encouraged people to order it, saying the box will ship in the third quarter.To read this article in full or to leave a comment, please click here

Microsoft’s new tools help devs manage cloud deployments on the go

Microsoft is making it easier for developers to manage their cloud deployments on the go, using a new mobile app and browser-based command line.On Wednesday, the company unveiled Azure Cloud Shell, which lets developers spin up a full-fledged terminal environment inside Microsoft’s cloud and comes with a set of preconfigured tools for managing deployments. Each user will have persistent file storage in their Cloud Shell, hosted in Microsoft Azure.Cloud Shells are accessible through the Microsoft Azure web portal, as well as the Azure mobile app for iOS and Android, which was just released Wednesday. That app also provides users with the ability to monitor the workloads they have running in Microsoft’s public cloud and perform basic management like stopping and restarting virtual machines.To read this article in full or to leave a comment, please click here

18 things you should know about using Linux tools in Windows 10

Last year Microsoft added an unusual new feature to Windows 10: Linux support. The Windows Subsystem for Linux (WSL) — sometimes called Bash on Windows — is “Microsoft’s implementation of a Linux-compatible infrastructure that runs atop and within the Windows kernel,” senior program manager Rich Turner tells CIO.com. That means running Linux binaries without leaving Windows.“Bash on Windows offers a toolset for developers, IT administrators and other tech professionals that want or need to run Linux command-line tools alongside their Windows tools and applications,” Turner explains. Developed with the help of Canonical (and a large community of Linux users), it’s not there to turn Linux into Windows, or Windows into Linux. It’s just that some Linux tools are so ubiquitous for development and deployment that it’s useful to be able to use them without spinning up a virtual machine (VM). That’s one of the reasons Macs are so popular with developers: MacOS is based on BSD, which is UNIX, so it can run Linux tools like Bash. And now, so can Windows 10.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Data virtualization: Like rocket fuel for your mainframe

It goes without saying that mainframes are powerful. These computers can perform more operations per second than any other commercial system, which is why most banks (not to mention many government agencies, insurance companies, retailers and other businesses that manage massive amounts of data) rely on Big Iron for their indispensable data analytics functions.And to say analytics are indispensable is underselling their value. Data analysis is an absolutely integral part of the new economy, and any organization seeking an edge needs an edge in analytics. Mainframes are a good match to provide the speed that leading companies are looking for, but many companies are still held back by their software.To read this article in full or to leave a comment, please click here

VMware unveils the latest nervous system for enterprise IoT

The internet of things seems tailor-made for management headaches. Having thousands of tiny devices distributed across a city or a company is hard enough. Then there's the whole infrastructure supporting them, including network connections and edge gateways.Some big players, including General Electric, Nokia, and Cisco's Jasper division, have products and services for running all this. Now VMware is taking on the challenge with VMware Pulse IoT Center, a solution that draws on two platforms the company already sells.To read this article in full or to leave a comment, please click here

IBM’s new PowerAI tools automate image recognition

IBM is trying to remove some of the complications related to image recognition with new tools to automate critical machine learning tasks.A major update of the company's PowerAI tools has a feature called AI Vision, an auto tuner that makes it easy to identify and classify pictures. It will also speed up image recognition by breaking down tasks over multiple clusters.AI Vision plays a big role in automating machine learning by creating a tuned model, said Sumit Gupta, vice president of machine learning.The software abstracts machine learning, and developers don't need knowledge of low-level access to frameworks to tune, train, and deploy image recognition models. It's much like programming a game to take advantage of GPUs without deep knowledge of low-level APIs.To read this article in full or to leave a comment, please click here

Reaction: Offensive Destruction of Attack Assets

It is certainly true that DDoS and hacking are on the rise; there have been a number of critical hacks in the last few years, including apparent attempts to alter the outcome of elections. The reaction has been a rising tide of fear, and an ever increasing desire to “do something.” The something that seems to be emerging is, however, not necessarily the best possible “something.” Specifically, governments are now talking about attempting to “wipe out” the equipment used in attacks—

Berlin was studying what legal changes were needed to allow authorities to purge stolen data from third-party servers, and to potentially destroy servers used to carry out cyber attacks. “We believe it is necessary that we are in a position to be able to wipe out these servers if the providers and the owners of the servers are not ready to ensure that they are not used to carry out attacks,” Maassen said. —Reuters

“Wiping out” (destroying?) a server because the owner cannot ensure the server will be used in a way the government agrees with—sounds like a good idea, right? And how do we make certain such laws are not extended to destroy the servers Continue reading

Microsoft takes its databases worldwide with Cosmos DB

Developers will have an easier time scaling their applications to meet global needs with a database product Microsoft updated on Wednesday. Called Cosmos DB, the service lets developers store data that can be replicated across any of the company’s 34 Azure public cloud regions.Cosmos is an expansion of DocumentDB, a managed NoSQL database service that Microsoft launched in 2015. Its key innovation is a feature that lets developers pick between five consistency models that range from "strong" to "eventual" consistency.To read this article in full or to leave a comment, please click here
