Intel Declares War on GPUs at Disputed HPC, AI Border

In Supercomputing Conference (SC) years past, chipmaker Intel has always come forth with a strong story, either as an enabling processor or co-processor force, or more recently, as a prime contractor for a leading-class national lab supercomputer.

But outside of a few announcements at this year’s SC related to beefed-up SKUs for high performance computing and Skylake plans, the real emphasis back in Portland seemed to ring far fainter for HPC and much louder for the newest server tech darlings, deep learning and machine learning. Far from the HPC crowd last week was Intel’s AI Day, an event in …

Details Emerge On “Summit” Power Tesla AI Supercomputer

The future “Summit” pre-exascale supercomputer that is being built out in late 2017 and early 2018 for the US Department of Energy for its Oak Ridge National Laboratory looks like a giant cluster of systems that might be used for training neural networks. And that is an extremely convenient development.

More than once during the SC16 supercomputing conference this week in Salt Lake City, the Summit system and its companion “Sierra” system that will be deployed at Lawrence Livermore National Laboratory, were referred to as “AI supercomputers.” This is a reflection of the fact that the national labs around the …

Networks Drive HPC Harder Than Compute

It is hard to tell which part of the HPC market is more competitive: compute, networking, or storage. From where we sit, there is an increasing level of competition on all three fronts and the pressure to perform, both financially and technically, has never been higher. This is great for customers, of course, who are being presented with lots of technology to choose from. But HPC customers tend to pick architectures for several generations, so there is also pressure on them to make the right choices – whatever that means.

In a sense, enterprises and hyperscalers and cloud builders, who …

Using GNOME Keyring as Git Credential Helper

In this post, I’m going to show you how to use the GNOME Keyring on Ubuntu 16.04 as a credential helper for Git. This post stems from my work in transitioning to Linux as my primary OS, an effort I’ve ratcheted up significantly in the last few weeks. What I’m including here isn’t new or ground-breaking information; I’m posting it primarily to make the information easier to find for others.

On Ubuntu 16.04, the basis for integrating GNOME Keyring into Git as a credential helper is already installed into the /usr/share/doc/git/contrib/credential/gnome-keyring directory. However, if you try to simply run sudo make in that directory, it will fail. In order to make it work, you must first install some additional development libraries:

sudo apt install libgnome-keyring-dev

Once you’ve installed this additional package, running sudo make in that directory will quickly compile a binary named git-credential-gnome-keyring. Once you have that binary, then you can configure Git to use GNOME Keyring as a credential helper. You can do this a couple of different ways:

1. You can use the git config command, like this:

    git config --global credential.helper /usr/share/doc/git/contrib/credential/gnome-keyring/git-credential-gnome-keyring
   

2. You can edit ~/.gitconfig directly, using the text editor of your Continue reading

Stacking Up Software To Drive FPGAs Into The Datacenter

Every new hardware device that offers some kind of benefit compared to legacy devices faces the task of overcoming the immense inertia that is imparted to a platform by the software that runs upon it. While FPGAs have so many benefits compared to general purpose CPUs and even GPUs because of their malleability, the inertia seems even heavier.

Any substantial change requires a big payoff to be implemented because change is inherently risky. It doesn’t help that the method of programming FPGAs efficiently using VHDL and Verilog are so alien to Java and C programmers, and that the tools for …

iPhone 8 launch will see Apple release 3 brand-new devices

Given that the overall design of the iPhone hasn't changed much since the release of the iPhone 6 back in 2014, there's a lot of pressure on Apple to deliver a home run when the company launches the iPhone 8 later next year.Though next year's iPhone would ordinarily be called the iPhone 7s, it's widely believed that Apple's next-gen iPhone will represent such a compelling upgrade that Apple will opt to call it the iPhone 8 instead.Now, as for what Apple has in store for us with the iPhone 8, the company's plans are beginning to crystalize slowly but surely. According to analyst Ming-Chi Kuo (via Apple Insider), Apple next year will introduce three distinct iPhone models.To read this article in full or to leave a comment, please click here

OFNet SDN network emulator

OFNet is a new software-defined network (SDN) emulator that offers functionality similar to the Mininet network emulator and adds some useful tools for generating traffic and monitoring OpenFlow messages and evaluating SDN controller performance.

OFNet is an open-source project that is distributed as a virtual machine (VM) image. The OFNet source code is available in the OFNet VM’s filesystem. In this post, we will use the OFNet VM provided by the OFNet developer to run SDN emulation scenarios in OFNet.

The OFNet Virtual Machine

The OFNet VM image is packaged as an OVA file which can be imported into most virtual machine managers. In this case, we are using VirtualBox. You may download the OFNet VM from this link.

The OFNet VM contains a Linux system running Ubuntu 12.04 and has the VirtualBox extensions installed.

Create a new virtual machine using the OFNet VM image, start up the VM and log in. After logging in, review the available OFNet documentation and install Wireshark.

Install the OFNet VM in VirtualBox

Import the OFNet.ova file into VirtualBox. Use the File → Import Appliance VirtualBx menu command or press <Ctrl-I>. Navigate to the location where you saved the OFNet.ova file Continue reading

Internet of Things Messaging, Part 1: Introducing MQTT

In the world of the Internet of Things one thing you’ve got lots of, apart from things, is messages. When IoT devices generate messages, they send stuff like status reports and environmental measurements; when they receive, they’re being told what to do (“open that valve” or “send your status”) or they’re storing data from other devices or, or ,or … there are endless use cases. Moreover, the number of IoT devices is growing incredibly fast and only their combined message traffic is growing faster. And as well as the explosion of the IoT, there are applications running on smartphones, tablets, and computers that all need the same type of messaging service.To read this article in full or to leave a comment, please click here

Reverese Shell on Linux

Reverse shell is technique when a client connects to a server and the client provides its shell to the server. Clients is typically a host hidden behind the NAT or a firewall having an access to the server but not vice versa. Thanks to a reverse shell the server controls a client's shell having an access to the client's network even the client is hidden behind the NAT. They are several methods how to create a reverse shell used depending on software available on the client. I will show how to create a reverse shell using SSH, Ncat and Bash.

Picture 1 - Network Topology

Picture 1 shows our testing topology. The client (Ubuntu Server 16.04) is located behind the NAT with the IP address 192.168.1.4/24. The server (Kubuntu 16.04) has assigned the IP address 172.17.100.7/16.

1. Reverse Shell Using SSH Reverse Tunnel

This method is based on the fact that the client has knowledge of the server SSH login credentials and vice versa. SSH server must be running on both the server and client. Client must be allowed to access server through firewall.

Client:
$ ssh -R 10000:127.0.0.1:22 [email protected]. Continue reading

Trump’s national security pick is a cybersecurity hawk

Michael Flynn, the man President-elect Donald Trump plans to name as U.S. national security advisor, believes the government is falling behind on cybersecurity. Trump named Flynn to his cabinet on Friday after the former military intelligence leader acted as the top military advisor to Trump's presidential campaign. Flynn previously was director of the Defense Intelligence Agency and has served in U.S. intelligence operations in Afghanistan and Iraq. Flynn holds strong views on cybersecurity. He’s called U.S. cyber capabilities “underwhelming.” “We have competitors out there that are rapidly catching up with us,” he said in a speech posted online last year. In 2014, after retiring as a general, he started a consulting firm called Flynn Intel Group that specializes in preventing cyber threats for clients.To read this article in full or to leave a comment, please click here

IoT attacks could bring real-world damage

Members of Congress received a dire warning this week about security vulnerabilities in the so-called internet of things (IoT), as cyber experts cautioned that with billions of new devices coming online, coordinated hacking attacks could become -- literally -- a matter of life and death.House lawmakers convened the hearing on IoT security in response to last month's distributed denial-of-service attack on the internet addressing provider Dyn, which resulted in temporary outages at popular sites like Twitter and Spotify.[ Related: How the Dyn DDoS attack unfolded ]To read this article in full or to leave a comment, please click here
