The X86 Battle Lines Drawn With Intel’s Skylake Launch

At long last, Intel’s “Skylake” converged Xeon server processors are entering the field, and the competition with AMD’s “Naples” Epyc X86 alternatives can begin and the ARM server chips from Applied Micro, Cavium, and Qualcomm and the Power9 chip from IBM know exactly what they are aiming at.

It is a good time to be negotiating with a chip maker for compute power.

The Skylake chips, which are formally known as the Xeon Scalable Processor family, are the result of the convergence of the workhorse Xeon E5 family of chips for two-socket and four-socket servers with the higher-end Xeon E7 …

Worth Reading: Internet of Terror

Before we get to the question of encryption and key length, I would like to point out two things. An IoT device is nothing more than an embedded system with a TCP/IP stack. It is not a magical object that is somehow protected from attackers because of how cool, interesting, or colorful it is. Second, and I can’t believe I have to point this out to people who would read or write to KV, but the Internet has a lot of stuff on it, and it’s getting bigger every day. Once upon a time, there were fewer than 100 nodes on the Internet, and that time is long past. KV has three Internet-enabled devices within arm’s reach, and, if you think a billion users of the Internet aren’t scary, try multiplying that by 10 once every fridge, microwave, and hotel alarm clock can spew packets into the ether(net). Let’s get this straight: if you attach something to a network—any network—it had better be secured as well as possible, because I am quite tired of being awakened by the sound of the gnashing of teeth caused by each and every new network security breach. The Internet reaches everywhere, and if even Continue reading

AI heading back to the trough

I like Gartner’s concept of the technology hype cycle. It assumes that expectations of new technologies quickly ramp to an inflated peak, drop into a trough of disillusionment, then gradually ascend a slope of enlightenment until they plateau. Of course, not all technologies complete the cycle or transition through the stages at the same pace.Artificial intelligence (AI) has arguably been in the trough for 60 years. I am thinking of Kubrick’s HAL and Roddenberry’s “computer” that naturally interact with humans. That’s a long trough, and despite popular opinion, the end is nowhere in sight.+ Also on Network World: Using artificial intelligence to teach computers to see + There’s so much excitement and specialized research taking place that AI has fragmented into several camps such as heuristic programming for game-playing AI, natural language processing for conversational AI, and machine learning for statistical problems. The hype is building again, and just about every major tech company and countless startups are racing toward another inflated peak and subsequent trough.To read this article in full or to leave a comment, please click here

China Tunes Neural Networks for Custom Supercomputer Chip

Supercomputing centers around the world are preparing their next generation architectural approaches for the insertion of AI into scientific workflows. For some, this means retooling around an existing architecture to make capability of double-duty for both HPC and AI.

Teams in China working on the top performing supercomputer in the world, the Sunway TaihuLight machine with its custom processor, have shown that their optimizations for theSW26010 architecture on deep learning models have yielded a 1.91-9.75X speedup over a GPU accelerated model using the Nvidia Tesla K40m in a test convolutional neural network run with over 100 parameter configurations.

Who Controls The Internet?

The title of the paper Who controls the Internet? Analyzing global threats using property traversal graphs is enough to ensnare any Internet researcher. The control plane for a number of attacks, as the paper points out, is the DNS due to the role it plays in mapping names to resources. MX records in the DNS control the flow of mail, CNAME records are used to implement content delivery networks (CDN) services, and TXT records are used to confirm access to and control over a namespace when implementing third party services. This post will cover an interesting case where control is exercised first via the DNS and then using BGP.

Below the DNS, in the depths of internet plumbing, is the lizard brain of internet routing, which is governed by the border gateway protocol (BGP). A common term to describe BGP routing is “hot potato” routing. BGP conversations occur between autonomous systems, ASes, which are identified by their autonomous system number ASN. The ASN represents a system of networks and the policy associated with their routing. ASes are issued regionally by Regional Internet Registries (RIRs), which receive blocks of AS numbers to hand out from the Internet Assigned Numbers Authority Continue reading

OpenPower, Efficiency Tweaks Define Europe’s DAVIDE Supercomputer

When talking about the future of supercomputers and high-performance computing, the focus tends to fall on the ongoing and high-profile competition between the United States with its slowly eroding place as the kingpin in the industry and China and the tens of billions of dollars that the government has invested in recent years to rapidly expand the reach of the country’s tech community and the use of home-grown technologies in massive new systems.

Both trends were on display at the recent International Supercomputing Conference in Frankfurt, Germany, where China not only continued to hold the top two spots on the …

IPv6 Link-Local Addresses and VLAN Interfaces

One of my readers sent me an email that’s easiest paraphrased into: “Why can’t I have a different IPv6 link-local address (LLA) on every access port connected to a VLAN interface?”

There’s probably nothing stopping someone from implementing such an approach, but it would go against the usual understanding of how bridging and routing interact in L2+L3 switches.

Interface basics on the Juniper MX

I’ve been spending more time on the MX recently and I thought it would be worthwhile to document some of the basics around interface configuration.  If you’re like me, and come from more of a Cisco background, some of configuration options when working with the MX weren’t as intuitive.  In this post, I want to walk through the bare bone basic of configuring interfaces on a MX router.

Basic L3 interface

ge-0/0/0 {
    unit 0 {
        family inet {
            address 10.20.20.16/24;
        }
    }
}

The most basic interface configuration possible is a simple routed interface. You’ll note that the interface address is configured under a unit. To understand what a unit is you need to understand some basic terminology that Juniper uses. Juniper describes a physical interface as an IFD (Interface Device). In our example above the IFD would be the physical interface ge-0/0/0. We can then layer one or more IFL (Interface Logical) on top of the IFD. In our example the IFL would be the unit configuration, in this case ge-0/0/0.0. Depending on the configuration of the IFD you may be able to provision additional units. These additional units (Logical interfaces (IFLs)) Continue reading

Docker for the SysAdmin Webinar Q&A

On June 27th I presented a webinar on “Docker for the SysAdmin”.  The webinar was driven by a common scenario I’m seeing: A sysadmin is sitting at her desk minding her own business when a developer walks in and says “here’s the the new app, it’s in a Docker image. Please deploy it ASAP”. This session is designed to help provides some guidance on how sysadmins should think about managing Dockerized applications in production.

In any case, I was a bit long-winded (as usual), and didn’t have time to answer all the Q&A during the webinar (and there were quite a few).

So, as promised, here are all the questions from that session, along with my answers.  If you need more info, hit me up on Twitter: @mikegcoleman

Q: I am planning an application deployment and want to use Docker. What cloud would you recommend at the moment? I have GCP, Azure, AWS under my belt. 1) TCO 2) Performance ?

A: Answering that would require me to understand your application on a pretty deep level, so I can’t really provide a specific response. I will say that if you choose one cloud provider today, and realize that Continue reading
