It is going to take a lot of different things to build an exascale system. One of them is money, and the other is a lot of good – and perhaps unconventional – ideas. It may also take more cooperation between the hyperscale and HPC communities, who both stand to benefit from the innovation.
As a professor of computer architectures at the University of Manchester, the director of technology and systems at chip designer ARM, and the founder of a company called Kaleao to create microservers that implement many of his architectural ideas, John Goodacre has some strong opinions about …

In the second post in this series, we considered the use of IGP-Prefix segments to carry a flow along a specific path in a data center fabric. Specifically, we looked at pulling the green flow in this diagram—
—along the path [A,F,G,D,E]. Let’s assume this single flow is an elephant flow that we’re trying to separate out from the rest of the traffic crossing the fabric. So—we’ve pulled the elephant flow onto its own path, but this still leaves other flows to simple ECMP forwarding through the fabric. This means some number of other flows are still going to follow the [A,F,G,D,E] path. The flows that are randomly selected (or selected by the ECMP has) to follow the same path as the elephant flow are still going to contend with the elephant flow for queue space, etc.
So we need more than just a way to pull an elephant flow onto a specific path. In fact, we also need a way to pull a specific set of flows off a particular path in the ECMP set. Returning to our diagram, assume we want all the traffic other than the elephant flow to be load shared between H and B, and Continue reading
New paper says machine learning will extend the life cycle of flash memory, which experiences "cell wear" with repeated use.
Following yesterday’s acquisition of deep learning chip startup Nervana Systems by Intel, we talked with the company’s CEO, Naveen Rao, about what plans are for both the forthcoming hardware and internally developed Neon software stack now that the technology is under a much broader umbrella.
Media outlets yesterday reported the acquisition was $350 million, but Rao tells The Next Platform it was not reported correctly and is actually more than that. He was not allowed to state the actual amount but said it was quite a bit higher than the figure given yesterday.
Nervana had been seeking a way to …

It’s been nearly two weeks since Docker released Docker 1.12 as generally available for production environments, introducing a number of new features and concepts to the Docker project. Our #DockerCaptain team has already started to dig in and share their learnings with the community via blog posts, talks and peer-to-peer help. Docker Captains are technology experts who have been awarded the distinction of being a Docker Captain in part because of their passion for sharing their Docker knowledge with others. So, we’ve invited three of our Docker Captains to speak at the next Docker Online Meetup on August 31st and share their tips and tricks for using Docker 1.12. Continue reading
Hey, it's HighScalability time:
The big middle finger to the Olympic Committee. They pulled this video of the incredibly beautiful Olympic cauldron at Rio.
We recently ran the 2016 version of our Ansible Community Survey. This is a survey of Ansible users and community members, regarding how they're using Ansible in their environments. We thought it would be useful to share some of the aggregate results. (As we did not ask for permission to distribute individual responses, we cannot make the raw data public.)
We had over 1,600 survey respondents, up from 1,300 when we last ran the survey in March of 2015.
How long have you been using Ansible? |

Ansible continues to grow more veteran users - when surveyed in 2015, only 30% of respondents had used Ansible for more than a year.
