Fedora Rawhide installation with 320 MB RAM

Filed under
Red Hat

The Anaconda OS installer used by Fedora, RHEL and their derivatives have been many times criticized for its memory requirements being bigger than memory requirements of the installed OS. Maybe a big surprise for users who don’t see too deep into the issue, no surprise for people who really understand what’s going on in the OS installation and how it all works. The basic truth (some call it an issue) about OS installation is that the installer cannot write to physical storage of the machine before user tells it to do so. However, since the OS installation is quite a complex process and since it has to be based on the components from the OS itself there are many things that have to be stored somewhere for the installer to work. The only space for data that for sure doesn’t contain any data the installer shouldn’t overwrite or leave some garbage in is RAM.

Red Hat

The second Alpha version of Scientific Linux 7.0, a recompiled Red Hat Enterprise Linux put together by various labs and universities around the world, is now available for download and testing.

The developers of Scientific Linux 7.0 have moved very fast and, just a week after the first Release Candidate, a new development release has been made available. Given the short development period since the first Alpha, it's actually surprising that the devs managed to get all those changes and improvements in.

“Fermilab's intention is to continue the development and support of Scientific Linux and refine its focus as an operating system for scientific computing. Today we are announcing an alpha release of Scientific Linux 7. We continue to develop a stable process for generating and distributing Scientific Linux, with the intent that Scientific Linux remains the same high quality operating system the community has come to expect.”

CentOS 7 Comes on the Heels of Red Hat Enterprise Linux 7

Filed under
Red Hat

The CentOS 7 Linux operating system became generally available July 7, providing users with a freely available desktop, server and cloud operating system platform. CentOS, an acronym for Community Enterprise Operating System, is based on the Red Hat Enterprise Linux (RHEL) 7 enterprise OS, released June 10. Unlike RHEL 7, which is a commercially supported enterprise Linux release that requires users to have a paid subscription, CentOS is free. That said, CentOS lacks the support, services and certifications that Red Hat provides its RHEL subscribers. CentOS does, however, provide the same basic technologies as RHEL 7, but for those who don't need or want the additional enterprise-grade commercial services, CentOS is a free alternative. Red Hat is now an official support and partner of the CentOS community, as well, ever since a surprise announcement in January. CentOS inherits the same XFS file system used in RHEL 7, which provides a file system that can scale up to 500 terabytes. Docker container virtualization support is also part of the CentOS 7 platform. In this slide show, eWEEK examines the CentOS 7 Linux operating system.

Filed under
Red Hat

A few weeks ago, I covered the news that Google had released Kubernetes under an open-source license, which is software to manage computing workloads across thousands of computer servers and leverage docker containers. We've also covered Google's announcement that some vey big contributors have joined the Kubernetes project, including IBM, Microsoft, Red Hat, Docker, CoreOS, Mesosphere, and SaltStack. They are working in tandem on open source tools and container technologies that can run on multiple computers and networks.

CentOS 6.5 vs. CentOS 7.0 NAS Performance Comparison

Filed under
Graphics/Benchmarks
Red Hat

RedHat Enterprise Linux is an enterprise-grade Linux distribution, which is frequently used in corporate data centers as an operating system for NAS storage devices. From the performance point of view, the new Linux kernel and the new default file system may have a significant impact on a NAS storage device and therefore it is very important to understand how the newly released RedHat Enterprise Linux version 7.0 compares to the last stable version 6.5.

FATHOM releases Crystallon

  • FATHOM releases Crystallon, an open-source software for lattice-based design
    Lattice structures are integral to 3D printed designs, and Aaron Porterfield, an industrial designer at additive manufacturing service bureau FATHOM, has developed Crystallon, an open source project for shaping them into structures.
  • FATHOM Introduces Open Source Software Project for Generating 3D Lattice Structures
    California-based FATHOM, which expanded its on-site managed services and announced important partnerships with Stratasys and Desktop Metal last year, is introducing a fascinating new open source project called Crystallon, which uses Rhino and Grasshopper3D to create lattice structures. FATHOM industrial designer Aaron Porterfield, also an Instructables member, developed the project as an alternative to designing lattices with commercially available software. He joined the company’s design and engineering team three years ago, and is often a featured speaker for its Design for Additive Manufacturing (DfAM) Training Program – and as the project developer, who better to explain the Crystallon project?

Kernel and Graphics: Machine Learning, Mesa, Wayland/Mir, AMDGPU

  • AI-Powered / Machine Learning Linux Performance Tuning Is Now A Thing
    A year and a half ago I wrote about a start-up working on dynamically-tuned, self-optimizing Linux servers. That company is now known as Concertio and they just launched their "AI powered" toolkit for IT administrators and performance engineers to optimize their server performance. Concertio Optimizer Studio is their product making use of machine learning that aims to optimize Linux systems with Intel CPUs for peak performance by scoping out the impact of hundreds of different tunables for trying to deliver an optimal configuration package for that workload on that hardware.
  • Pengutronix Gets Open-Source 3D Working On MX8M/GC7000 Hardware
    We've known that Pengutronix developers had been working on i.MX8M / GC7000 graphics support within their Etnaviv open-source driver stack from initial patches posted in January. Those patches back at the start of the year were for the DRM kernel driver, but it turns out they have already got basic 3D acceleration working.
  • SDL Now Disables Mir By Default In Favor Of Wayland Compatibility
    With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move.
  • Mesa 18.1 Receives OpenGL 3.1 With ARB_compatibility For Gallium3D Drivers
    Going back to last October, Marek of AMD's open-source driver team has been working on ARB_compatibility support for Mesa with a focus on RadeonSI/Gallium3D. Today that work was finally merged. The ARB_compatibility support allows use of deprecated/removed features of OpenGL by newer versions of the specification. ARB_compatibility is particularly useful for OpenGL workstation users where there are many applications notorious for relying upon compatibility contexts / deprecated GL functionality. But ARB_compatibility is also used by a handful of Linux games too.
  • AMDGPU In Linux 4.17 Exposes WattMan Features, GPU Voltage/Power Via Hwmon
    AMD's Alex Deucher today sent in the first pull request to DRM-Next of AMDGPU (and Radeon) DRM driver feature material that will in turn be merged with the Linux 4.17 kernel down the road. There's some fun features for AMDGPU users coming with this next kernel! First up, Linux is finally getting some WattMan-like functionality after it's been available via the Windows Radeon Software driver since 2016. WattMan allows for more fine-tuning of GPU clocks, voltages, and more for trying to maximize the power efficiency. See the aforelinked article for details but currently without any GUI panel for tweaking all of the driver tunables, this WattMan-like support needs to be toggled from the command-line.
