Things get a little wonky at exascale and hyperscale. Things that don’t matter quite as much at enterprise scale, such as the cost or the performance per watt or the performance per dollar per watt for a system or a cluster, end up dominating the buying decisions. …

How do we work toward a more secure Internet?
In the Cyber Security discussions that take place in the various policy fora around the world, there is often little appreciation that the security of the Internet is a distributed responsibility, where many stakeholders take action.
By design, the Internet is a distributed system with no central core or point of control. Instead, Internet security is achieved by collaboration where multiple companies, organizations, governments, and individuals take action to improve the security and trustworthiness of the Internet – so that it is open, secure, and available to all.
Today we’ve published Major Initiatives in Cybersecurity: Public & Private Contributions Towards Increasing Internet Security to illustrate, via a handful of examples regarding Internet Infrastructure, there are a great number initiatives working, sometimes together and sometimes independently, in improving the Internet’s security. An approach we call collaborative security.
Major Initiatives in Cybersecurity describes Internet security as the part of cybersecurity that, broadly speaking, relates to the security of Internet infrastructure, the devices connected to it, and the technical building blocks from which applications and platforms are built.
We make no claim to completeness, but we do hope that the paper illustrates the complexity, breath, Continue reading

If you operate a data-center network with Cisco Nexus, you’ve probably already faced the problem of how to perform a maintenance on one of the two switches of a vPC pair, with minimum impact and risks for the production network. Cisco NX-OS contains a feature called “Graceful Insertion and Removal” or GIR to help you for that. Here is how it works. Scenario Let’s take the example below: (click on the image to see a larger version) We have two Nexus (in nx-os mode) in vPC. Doing layer-2 aggregation and …

At every key leap in processing capacity in high performance computing – and just rattling off more than two decades from teraflops through petaflops, and now on the verge of exaflops in two years or so – there has been this tension between custom-built systems that break through performance barriers and more general purpose machines based on more off of the shelf components that cost less and tend to be fast followers. …

No.
It’s the shortest sentence in the English language. It requires no other parts of speech. It’s an answer, a statement, and a command all at once. It’s a phrase that some people have zero issues saying over and over again. And yet, some others have an extremely difficult time answering anything in the negative.
I had a fun discussion on twitter yesterday with some friends about the idea behind saying “no” to people. It started with this tweet:
Coincidentally, I tweeted something very similar to what Bob Plankers had tweeted just hours before:
The gist is the same though. Crazy features and other things that have been included in software and hardware because someone couldn’t tell another person “no”. Sadly, it’s something Continue reading

The last Software Gone Wild podcast recorded in 2019 focused on advances in Linux networking - in particular on interesting stuff presented at NetDev 0x13 conference in Prague. The guests (in alphabetical first name order) Jamal Hadi Salim, Shrijeet Mukherjee, Sowmini Varadhan, and Tom Herbert shared their favorite topics, and commented on the future of Linux networking.
Read more ...Ten challenges for making automation a ‘team player’ in joint human-agent activity, Klein et al., IEEE Computer Nov/Dec 2004
With thanks to Thomas Depierre for the paper suggestion.
Last time out we looked at some of the difficulties inherit in automating control systems. However much we automate, we’re always ultimately dealing with some kind of human/machine collaboraton. Today’s choice looks at what it takes for machines to participate productively in collaborations with humans. Written in 2004, the ideas remind me very much of Mark Burgess’ promise theory, which was also initially developed around the same time.
If a group of people (or people and machines) are going to coordinate with each other to achieve a set of shared ends then there are four basic requirements that must be met to underpin their joint activity:
A basic compact is…
… an agreement (often tacit) to facilitate coordination, work toward shared goals, and prevent breakdowns in team coordination. This Compact involves a commitment Continue reading
We have been waiting for a long, long time for the ionic bond between compute and main memory to be softened to something a little more covalent and therefore allow for more complex storage structures to be formed within systems and across them. …
