  • 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.

  • AMD Rolls Out ROCm 1.7 Platform For Supercomputing 17

    AMD has unveiled the Radeon Open Compute platform (ROCm) 1.7 release as part of their wares at this week's Supercomputing 17 (SC17) conference in Denver.

    The ROCm 1.7 update introduces multi-GPU support for "the latest Radeon GPU hardware" (presumably referring to Vega) while also supporting TensorFlow and Caffe via AMD's MIOpen libraries.

  • Red Hat introduces Arm server support for Red Hat Enterprise Linux
  • Red Hat Enterprise Linux for ARM64
  • Red Hat Enterprise Linux for ARM Hits General Availability

    Red Hat now considers their ARM support on Red Hat Enterprise Linux (RHEL7) to be supported under general availability "GA" terms.

  • 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.

Wine and Games for GNU/Linux

  • Wine 3.13 is out as well as DXVK 0.63 for D3D11 with Vulkan
    First of all the latest Wine development release is out with Wine 3.13 and on top of that DXVK for Vulkan-based D3D11 in Wine also release version 0.63.
  • Feral's GameMode 1.2 Released For Optimizing Linux Gaming
    For what just started out as a tool to ensure you are using the "performance" frequency scaling governor when running Linux games, Feral's open-source GameMode system tool has slowly been picking up some extra functionality. Out this weekend is Feral GameMode 1.2 as the newest release. GameMode 1.2 adds configuration options about the default and desired governors, now supports soft real-time scheduling on kernels with SCHED_ISO support and will then use renice to boost games to a higher priority, the GameMode service is now D-Bus activated than needing to be explicitly enabled by systemd, and the GameMode libraries are now properly versioned.
  • Stardew Valley multiplayer just got a PC release date
    Since the moment Stardew Valley launched back in 2016, multiplayer has been one of the most anticipated additions to the games. After a period of beta testing, it’s nearly ready to roll out on PC, Mac, and Linux. While it probably isn’t going to look a lot different from the beta that’s currently available, this is exciting news for more reasons than one.
  • Multiplayer is coming to ‘Stardew Valley’ on PC, Mac and Linux
    According to a tweet from Eric Barone (@ConcernedApe), the sole developer behind Stardew Valley, the feature is coming to the lighthearted farming game on August 1st. Along with the release date, the game’s developer also released a new trailer for the feature (see it above).

Jonathan Dieter: Small file performance on distributed filesystems - Round 2

Last year, I ran some benchmarks on the GlusterFS, CephFS and LizardFS distributed filesystems, with some interesting results. I had a request to redo the test after a LizardFS RC was released with a FUSE3 client, since it is supposed to give better small file performance. I did have a request last time to include RozoFS, but, after a brief glance at the documentation, it looks like it requires a minimum of four servers, and I only had three available. I also looked at OrangeFS (originally PVFS2), but it doesn’t seem to provide replication, and, in preliminary testing, it was over ten times slower than the alternatives. NFS was tested and its results are included as a baseline. I once again used compilebench, which was designed to emulate real-life disk usage by creating a kernel tree, reading all the files in the tree, simulating a compile of the tree, running make clean, and finally deleting the tree. The test was much the same as last time, but with one important difference. Last time, the clients were running on the same machines that were running the servers. LizardFS benefited hugely from this as it has a “prefer local chunkserver” feature that will skip the network completely if there’s a copy on the local server. This time around, the clients were run on completely separate machines from the servers, which removed that advantage for LizardFS, but which I believe is a better reflection on how distributed filesystems are generally used. I would like to quickly note that there was very little speed difference between LizardFS’s FUSE2 and FUSE3 clients. The numbers included are from the FUSE3 client, but they only differed by a few percentage points from the FUSE2 client. Read more

GNOME 3.30 Desktop Environment to Enter Beta on August 1, GNOME 3.29.4 Is Out

With a two-day delay, the GNOME Project through Javier Jardón announced today the release of the fourth and last development snapshot of the GNOME 3.30 desktop environment before it enters beta testing next month, GNOME 3.29.4, which continues to add improvements to various of GNOME's core components and applications. However, due to the summer vacation and the GUADEC conference, GNOME 3.29.4 isn't a major snapshot as many would have expected. It only adds some minor changes and bug fixes to a handful of components, including GNOME Shell, Mutter, Evolution, GNOME Photos, GNOME Builder, GNOME Online Accounts, Polari, Bijiben, Evince, Epiphany, Baobab, GNOME Control Center, and File Roller.
