  • Move Over, China: U.S. Is Again Home to World's Speediest Supercomputer [Ed: In Top 500 everything runs GNU/Linux]
  • IBM's world-class Summit supercomputer gooses speed with AI abilities
  • The US again has the world's most powerful supercomputer
  • The US Again Has World’s Most Powerful Supercomputer

    Plenty of people around the world got new gadgets Friday, but one in Eastern Tennessee stands out. Summit, a new supercomputer unveiled at Oak Ridge National Lab is, unofficially for now, the most powerful calculating machine on the planet. It was designed in part to scale up the artificial intelligence techniques that power some of the recent tricks in your smartphone.

    America hasn’t possessed the world’s most powerful supercomputer since June 2013, when a Chinese machine first claimed the title. Summit is expected to end that run when the official ranking of supercomputers, from an organization called Top500, is updated later this month.

    [...]

    Summit has nearly 28,000 graphics processors made by Nvidia, alongside more than 9,000 conventional processors from IBM. Such heavy use of graphic chips is unusual for a supercomputer, and it should enable breakthroughs in deploying machine learning on tough scientific problems, says Thomas Zacharia, director of Oak Ridge National Lab. “We set out to build the world’s most powerful supercomputer,” he says, “but it's also the world’s smartest supercomputer.”

  • IBM and the DoE launch the world’s fastest supercomputer

    IBM and the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) today unveiled Summit, the department’s newest supercomputer. IBM claims that Summit is currently the world’s “most powerful and smartest scientific supercomputer” with a peak performance of a whopping 200,000 trillion calculations per second. That performance should put it comfortably at the top of the Top 500 supercomputer ranking when the new list is published later this month. That would also mark the first time since 2012 that a U.S.-based supercomputer holds the top spot on that list.

    [...]

    IBM was the general contractor for Summit and the company collaborated with Nvidia, RedHat and InfiniBand networking specialists Mellanox on delivering the new machine.

  • Designing new cloud architectures: Exploring CI/CD – from data centre to cloud

    Nobody knows what DevOps really is, but if you are not doing, using, breathing, dreaming – being? – DevOps, you’re doing it wrong. All teasing aside, with the advent of DevOps, the gap that existed between development teams and operation teams has become closer, to the extent of some companies mixing the teams. Even so, some of those took a different approach and have multidisciplinary teams where engineers work on the product throughout the lifecycle, coding, testing and deploying – including on occasion security teams as well, now called DevOpsSec.

  • How not to kill your DevOps team
  • Kubernetes Deep Dive and Use Cases

    When containers were first introduced in 2008, Virtual Machines, or VMs, were the state-of-the-art option to optimize a data center’s physical resources. This arrangement worked well enough, but had some flaws: Virtual machines utilized too many resources because they required both a complete operating system, and emulated instructions to reach the physical CPU. Even with some technologies like Intel VT-x and AMD-V that attempted to solve the emulation problem, virtual machines were behind bare metal.

  • Mesos and Kubernetes: It's Not a Competition

    The project was founded in 2009. In 2010 the team decided to donate the project to the Apache Software Foundation (ASF). It was incubated at Apache and in 2013, it became a Top-Level Project (TLP).

    There were many reasons why the Mesos community chose Apache Software Foundation, such as the permissiveness of Apache licensing, and the fact that they already had a vibrant community of other such projects.  

    It was also about influence. A lot of people working on Mesos were also involved with Apache, and many people were working on projects like Hadoop. At the same time, many folks from the Mesos community were working on other Big Data projects like Spark. This cross-pollination led all three projects -- Hadoop, Mesos, and Spark -- to become ASF projects.

  • Why Linux Works [Ed: it says "This article was originally published in October, 2017"]

    The Linux community works, it turns out, because the Linux community isn’t too concerned about work, per se. As much as Linux has come to dominate many areas of corporate computing – from HPC to mobile to cloud – the engineers who write the Linux kernel tend to focus on the code itself, rather than their corporate interests therein.

    Such is one prominent conclusion that emerges from Dawn Foster’s doctoral work, examining collaboration on the Linux kernel. Foster, a former community lead at Intel and Puppet Labs, notes, “Many people consider themselves a Linux kernel developer first, an employee second.”

    With all the “foundation washing” corporations have inflicted upon various open source projects, hoping to hide corporate prerogatives behind a mask of supposed community, Linux has managed to keep itself pure. The question is how.

  • Easier container security with entitlements

    During KubeCon + CloudNativeCon Europe 2018, Justin Cormack and Nassim Eddequiouaq presented a proposal to simplify the setting of security parameters for containerized applications. Containers depend on a large set of intricate security primitives that can have weird interactions. Because they are so hard to use, people often just turn the whole thing off. The goal of the proposal is to make those controls easier to understand and use; it is partly inspired by mobile apps on iOS and Android platforms, an idea that trickled back into Microsoft and Apple desktops. The time seems ripe to improve the field of container security, which is in desperate need of simpler controls.

  • Kubernetes, Four Years Later, and Amazon Redefining Container Orchestration

    Well, here we are. Kubernetes turns four years old this month—technically, on June 7, 2018—the very same platform that brings users and data center administrators scalable container technologies. Its popularity has skyrocketed since its initial introduction by Google. Celebrating the project’s birthday is not the only thing making the headlines today. Amazon recently announced the general availability of its Elastic Container Services for Kubernetes (EKS), accessible via Amazon Web Services (AWS).

    Once upon a time, it wasn’t a simple task to orchestrate and manage containers in the cloud. Up until this recent EKS announcement, it was up to the administrator to spin up a virtual machine through an Elastic Cloud Compute (EC2) service, run Kubernetes on top of a traditional Linux server installation in EC2 and rely on other AWS moving components to host the container image registry. The entire process was very involved. Not any more!

Buildah 1.0: Linux Container construction made easy

Filed under
Linux
Server

The good news about containers, such as Docker's, is they make it easy to deploy applications, and you can run far more of them on a server than you can on a virtual machine. The bad news is that putting an application into a container can be difficult. That's where Buildah comes in.

Buildah is a newly released shell program for efficiently and quickly building Open Container Initiative (OCI) and Docker compliant images and containers. Buildah simplifies the process of creating, building, and updating images while decreasing the learning curve of the container environment.

  • Helm moves out of Kubernetes’ shadow to become stand-alone project

    Helm is an open source project that enables developers to create packages of containerized apps to make installation much simpler. Up until now, it was a sub-project of Kubernetes, the popular container orchestration tool, but as of today it is a stand-alone project.

    Both Kubernetes and Helm are projects managed by the Cloud Native Computing Foundation (CNCF). The CNCF’s Technical Oversight Committee approved the project earlier this week. Dan Kohn, executive director at the CNCF says the two projects are closely aligned so it made sense for Helm to be a sub-project up until now.

  • Helm, an open-source project for managing Kubernetes apps, gets its own home inside the Cloud Native Computing Foundation

    Another project has joined the Cloud Native Computing Foundation, after members voted to include Helm at the incubation stage within the organization’s roster of open-source projects.

    Helm was originally developed at Google and Deis, which was acquired by Microsoft last year. It is designed to help users of the Kubernetes container-orchestration project (also under the CNCF’s wing) find packages that facilitate the deployment of apps on Kubernetes.

  • LINBIT to Bring Open Source Block Storage to Containers

    Containerized applications now can access block storage typically accessed by high-performance storage systems supporting enterprise applications based on relational databases thanks to LINBIT.

    Available now in beta, LINSTOR is block storage software native to containers and is compatible with both Kubernetes clusters and the OpenShift platform-as-a-service (PaaS) environment from Red Hat, via support for the Container Storage Interface (CSI) being developed by the Cloud Native Computing Foundation (CNCF).

    LINBIT COO Brian Hellman says LINSTOR is the latest addition to a portfolio of open source software-defined storage (SDS) offerings that make it possible for IT organizations to employ any underlying storage hardware they want to access block-based storage.

  • Meet Aptomi: An application delivery engine for Kubernetes

    Kubernetes may rule the data center but if you have hundreds and thousands of containers running on it, it can be difficult to understand which applications they belong to, who owns them, why they were created, what’s no longer in use and the impact of changes.

    Enter Aptomi, an open-source project that simplifies roll out and operation of container-based applications on Kubernetes. It introduces a service-centric abstraction, allowing dev teams to compose applications from multiple components connected together. These components can be packaged via Helm, k8s YAMLs, ksonnet, or defined in any other Kubernetes-friendly way.

  • Kubernetes Gets Containerd Runtime Option

    Containerd integration is now generally available as a runtime option for the open source Kubernetes container orchestration system.

    While Docker is the dominant player among container runtimes, some experts in the field believe other options such as containerd can sometimes be the better choice.

    With that in mind, engineers from Google, Docker, IBM, ZTE and ZJU have developed a way to use containerd instead of Docker. While it may seem strange that Docker Inc. is involved what appears to be a competing project, the company actually initiated the containerd project before donating it to the community, and the Docker engine is based on it.

How open source supports CERN's Large Hadron Collider

Filed under

OSS

The 27-kilometre-long Large Hadron Collider (LHC) buried beneath the France-Switzerland border near Geneva is best known for helping to prove the existence of the Higgs' Boson particle - otherwise known as the God particle - crucial to the Standard Model of particle physics.

The LHC, which uses superconducting magnets to steer beams through its long pipes at just below the speed of light, is supported by open source IT systems at CERN to crunch through about 60 petabytes of data a year. These are built with Openstack, a free and open source software platform for building clouds.

The Openstack cloud first went into production at CERN in July 2013, marking the 13,000-physicist-strong laboratory as an early adopter. Today it has scaled to roughly 300,000 cores – and it's this kind of high-powered, scalable, open source cloud computing that got the attention of many private enterprises, now contributing to the code.

Kubuntu 18.04 Bionic Beaver upgrades - Results!

A month later, two upgrades later, Kubuntu 18.04 Bionic Beaver is a nicer distribution than what I tested shortly after its official release. But then, it's not perfect. The older box with the Nvidia card returned better results overall, although there were some niggles. On the multi-boot laptop, I wasn't too happy with the slow-boot issue, although this is NOT a Kubuntu-specific problem, as you will learn in a few days. But it still does not give me the razor-sharp confidence I need and expect from an LTS. In general, Ubuntu-family upgrades are reasonably robust, but they can still be more streamlined, including package removal, third-party repos and odd glitches here and there. I wonder how I'd have felt if I tested Beaver fresh, right now. Alas, I cannot delete the memory of my first encounter. With Trusty, it was just right. Here, it might be right, and I may even end up using - and loving - Plasma Bionic in my prod setup, but it will never be the amazing chemistry I had with 14.04. But if you're wondering, by all means, worth testing and upgrading, and the post-release Kubuntu Beaver is a pretty slick and tight distro. If I had to judge in isolation, i.e. no early-May scars, then when I combine performance, looks, fonts, media, hardware support, and such, 'tis really neat. Something like 9/10. Now, just waiting for the Men In Black mind-zapping eraser thingie, so I can be blissfully happy. And we're done. Read more
