  • Linux Now Powers 100% of the World’s Top 500 Supercomputers

    Linux now powers 100% of the world’s 500 fastest supercomputers. That’s according to the latest stats out from supercomputer hawks TOP500, who post a biannual list of the world’s most powerful commercially available computer systems. Linux has long dominated the TOP500 list, powering the majority of the machines that make it.

  • Linux Now Powers ALL TOP500 Supercomputers In The World | TOP500 List 2017
  • China Now Has More Supercomputers Than Any Other Country


    China now has more of the world’s most powerful computer systems than any other country, replacing the U.S as the dominant nation on the list of the planet’s 500 fastest supercomputers.

  • China Overtakes US in Latest Top 500 Supercomputer List


    China now claims 202 systems within the Top 500, while the United States -- once the dominant player -- tumbles to second place with 143 systems represented on the list.

    Only a few months ago, the US had 169 systems within the Top 500 compared to China's 160.

  • IT disaster recovery: Sysadmins vs. natural disasters

    In terms of natural disasters, 2017 has been one heck of a year. Hurricanes Harvey, Irma, and Maria brought destruction to Houston, Puerto Rico, Florida, and the Caribbean. On top of that, wildfires burned out homes and businesses in the West.

    It’d be easy to respond with yet another finger-wagging article about preparing for disasters—and surely it’s all good advice—but that doesn’t help a network administrator cope with the soggy mess. Most of those well-meant suggestions also assume that the powers that be are cheerfully willing to invest money in implementing them.

  • OCI Update: v1.0.1 Release and New Maintainer

    The OCI community continues to be hard at work, having just issued the first update to OCI v.1.0, after five months of focusing on stability. OCI 1.0.1 contains updates to both the image format and runtime specifications.

    We’re still growing and expanding, with even more collaboration since the launch of v 1.0. For example, we are now up to over 5,000 commits from 184 authors across 42 different organizations. Organizations like AWS, Docker, Cloud Foundry, CoreOS, Intel, Mesosphere, Oracle, Red Hat and Kubernetes have already taken advantage of the OCI v1.0 specifications, and with v1.0.1 now available, the industry is on the precipice of true portability and standardization. We had a strong showing on site at recent industry events, at both DockerCon Europe in Copenhagen and Open Source Summit Europe in Prague.

  • How enterprise IT uses Kubernetes to tame container complexity

    Running a few standalone containers for development purposes won’t rob your IT team of time or patience: A standards-based container runtime by itself will do the job. But once you scale to a production environment and multiple applications spanning many containers, it’s clear that you need a way to coordinate those containers to deliver the individual services. As containers accumulate, complexity grows. Eventually, you need to take a step back and group containers along with the coordinated services they need, such as networking, security, and telemetry.

    That’s why technologies like the open source Kubernetes project are such a big part of the container scene.

  • ARM emulator in a VM? Yup, done. Ready to roll, no config required

    Hacking low-level code on ARM processors just became a little easier after a researcher who operates under the name Azeria Labs put together virtual machines that emulate common hardware.

  • Orange and Red Hat push open source NFVi development

    At the OpenStack Summit 2017, operator Orange has joined forces with equally colourful open-source software vendor Red Hat to promote NFVi innovation.

    Sadly the two companies have missed a trick by declining to name their mutual endeavour Orange Hat, but we mustn’t let that detract from the underlying cleverness. Orange seems to reckon network functions virtualization infrastructure is best done in the open-source environment and Red Hat unsurprisingly agrees.

  • China Pulls Ahead of U.S. in Latest TOP500 List

    The fiftieth TOP500 list of the fastest supercomputers in the world has China overtaking the US in the total number of ranked systems by a margin of 202 to 143. It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the US presence shrinking to its lowest level since the list’s inception 25 years ago.

Server: MongoDB 3.6, Web Component. PHP 7.2.0 RC6

  • MongoDB 3.6 runs at the 'speed of data'

    MongoDB 3.6 will be generally available in early December.

    The open source (at its core) general purpose database has some noteable changes (its makers would call them enhancements) including a so-called ‘change streams’ feature, which enable developers to build what are being described as more ‘reactive’ web, mobile and IoT applications that can view, filter and act on data changes as they occur in the database.

  • I wrote a Web Component

    I’ve been meaning to play with Web Components for a little while now. After I saw Ben Nadel create a Twitter tweet progress indicator with Angular and Lucas Leandro did the same with Vue.js I thought, here’s a chance to experiment.

    Web Components involve a whole bunch of different dovetailing specs; HTML imports, custom elements, shadow DOM, HTML templates. I didn’t want to have to use the HTML template and import stuff if I could avoid it, and pleasantly you actually don’t need it. Essentially, you can create a custom element named whatever-you-want and then just add content here elements to your page, and it all works. This is good.

  • PHP 7.2.0RC6 Released

    The PHP development team announces the immediate availability of PHP 7.2.0 RC6. This release is the sixth Release Candidate for 7.2.0. Barring any surprises, we expect this to be the FINAL release candidate, with Nov 30th's GA release being not-substantially different. All users of PHP are encouraged to test this version carefully, and report any bugs and incompatibilities in the bug tracking system.

  • PHP 7.2 Is One Step Away From Release

    This week marked the sixth and final planned release candidate for PHP 7.2.

    This release is the final step before the official PHP 7.2 debut that is slated for 30 November unless there are any last minute blockers.

  • What is OpenHPC?

    High performance computing (HPC)—the aggregation of computers into clusters to increase computing speed and power—relies heavily on the software that connects and manages the various nodes in the cluster. Linux is the dominant HPC operating system, and many HPC sites expand upon the operating system's capabilities with different scientific applications, libraries, and other tools.

    As HPC began developing, that there was considerable duplication and redundancy among the HPC sites compiling HPC software became apparent, and sometimes dependencies between the different software components made installations cumbersome. The OpenHPC project was created in response to these issues. OpenHPC is a community-based effort to solve common tasks in HPC environments by providing documentation and building blocks that can be combined by HPC sites according to their needs. 

  • Containerd Brings More Container Runtime Options for Kubernetes

    A container runtime is software that executes containers and manages container images on a node. Today, the most widely known container runtime is Docker, but there are other container runtimes in the ecosystem, such as rkt, containerd, and lxd. Docker is by far the most common container runtime used in production Kubernetes environments, but Docker’s smaller offspring, containerd, may prove to be a better option. This post describes using containerd with Kubernetes.

  • Prometheus 2.0 Arrives with a Speedy New Local Storage Engine

    Improved local storage is at the heart of the new release of Prometheus 2.0, according to Fabian Reinartz, a CoreOS software engineer and a core developer of the Prometheus monitoring system.

    With distributed system coordination software such as Kubernetes and Mesos, monitored environments have become increasingly more dynamic, Reinartz pointed out in a blog post. The motioning software needed its own dedicated storage to ensure responsiveness in these dynamic environments.

    Though Prometheus 1.6 introduced auto-tuning capabilities, the team has been working on a more performant time-series database. “It’s just way more reliable and faster. Ideally, you don’t want to have to reconfigure all the time, so Prometheus just responds to change in demands, so there are way fewer knobs to turn for the people running it,” Reinartz said in an interview.

The OpenStack Foundation starts to look at projects beyond OpenStack

Filed under

Over the last few years, we’ve seen the launch of a number of open source foundations like the Cloud Native Compute Foundation, the Cloud Foundry Foundation and others. Most of these run under the Linux Foundation, but one of the largest open source foundation outside of that group’s orbit is the OpenStack Foundation, which — at least until now — has solely focused on the development of the OpenStack cloud computing platform.

  • Arduino Upgrades Cloud Platform, Supports Linux Devices

    Arduino unveils a set of added features for its Create Cloud platform ( aimed at expanding the number of Arduino-supported platforms for the development of IoT applications. With this release, Arduino Create Cloud users can now program Linux boards as if they were regular Arduino boards. Multiple Arduino programs can run simultaneously on a Linux-based board and programs can communicate with each other leveraging the capabilities of the latest Arduino Connector.


    Arduino has also developed a unique out-of-the-box experience that enables anybody to set up a new device from scratch from the cloud without any previous knowledge by following an intuitive web based wizard. The initial release has been sponsored by Intel and supports X86/X86_64 boards. As a reference implementation, a simplified user experience has been designed for the AAEON UP board, although other platforms are already supported by the Arduino Create Cloud platform (Intel NUC, Dell Wyse, Gigabyte GB-BXT).

  • Canonical insists containers are 'step change' for virtualisation era

    Container technology can combine speed and density with the security of traditional virtual machines and requires far smaller footprint operating systems in order to run.

    Containers offer a new form of virtualisation, providing almost equivalent levels of resource isolation as a traditional hypervisor.

    Additionally, containers present lower overheads both in terms of lower memory footprint and higher efficiency. This means that higher density can be achieved – simply put, you can get more for the same hardware.

  • OpenStack’s next mission: bridging the gaps between open source projects

    OpenStack, the massive open source project that provides large businesses with the software tools to run their data center infrastructure, is now almost eight years old. While it had its ups and downs, hundreds of enterprises now use it to run their private clouds and there are even over two dozen public clouds that use the project’s tools. Users now include the likes of AT&T, Walmart, eBay, China Railway, GE Healthcare, SAP, Tencent and the Insurance Australia Group, to name just a few.

    “One of the things that’s been happening is that we’re seven years in and the need for turning every type of infrastructure into programmable infrastructure has been proven out. “It’s no longer a debate,” OpenStack COO Mark Collier told me ahead of the projects semi-annual developer conference this week. OpenStack’s own surveys show that the project’s early adopters, who previously only tested it for their clouds, continue to move their production workflows to the platform, too. “We passed the hype phase,” Collier noted.

We must therefore track down these instructions and offer a supported alternative. Previously, we introduced a special configuration setting that might be used to indicate to the compiler when to choose these alternative sequences of instructions: CPU_MIPS32_R1. This gets expanded to CONFIG_CPU_MIPS32_R1 by the build system and it is this identifier that gets used in the program code.
