Clear Linux

Draft:Clear Linux

Intel's container Linux distribution, Draft:Clear Linux article has started, would you like to contribute? .... 0mtwb9gd5wx (talk) 23:12, 24 August 2021 (UTC)

Hey dude, thanks for including me. I will help with the project and started a thread on Clear Linux forums and installed it in a VM. --Leo Navis (talk) 15:59, 25 August 2021 (UTC)

@Leo Navis: could you look over Draft:Clear Linux article ? .... 0mtwb9gd5wx (talk) 17:23, 31 August 2021 (UTC)

"Ausprobiert: Clear Linux, Intels leistungsfähige Linux-Distribution". heise online (in German). 2020-04-30.
would you be able to google translate the article and correct the big mistakes? thanks .... 0mtwb9gd5wx (talk) 17:39, 31 August 2021 (UTC)

Clear Linux supports Sandy Bridge CPUs and later,[31] including 2nd Generation Intel® Core™, Intel® Xeon® Processor E3, Intel® Atom™ processor C2000 (Q3 2013 or later), Intel® Atom™ processor E3800 (Q4 2013 or later). In the heise-article it's stated that Die konkreten Mindestanforderungen listen die Befehlserweiterungen Intel SSSE3, SSE 4.1, SSE 4.2 und Carry-less Multiplication (CLMUL) auf. Zudem verlangt die Installation von Clear Linux nach UEFI. which translates to The minimum system requirements list Intel SSSE3, SSE 4.1, SSE 4.2 and CLMUL, as well as UEFI. That should be in the draft I think. The article also discusses what I have been stated in the discussion of the draft: Clear Linux ist auf dem Desktop mangels Paketen deshalb kein universell einsetzbares Linux-System im Stil von Debian, Ubuntu, Fedora oder auch Arch Linux. which translates to Clear Linux is because of the small amount of available packages not a universally usable Linux-system like Debian, Ubuntu, Fedora or Arch Linux. I think we should include that; I believe a lot of the speed comes from just not including stuff. --Leo Navis (talk) 19:50, 31 August 2021 (UTC)

Tried: Clear Linux, Intel's powerful Linux distribution

More powerful than other Linux systems? Clear Linux focuses on server- and cloud-systems, but invites you to try it out on the desktop.

by David Wolski

At the OpenStack Summit 2015, Intel presented its own Linux distribution Clear Linux for the first time, which should work particularly well on the manufacturer's hardware. Only a year ago, the distribution, which was initially presented as a tailor-made operating system for lean containers and servers in the cloud, received a graphical installation program in a live system with a Gnome desktop.

Most recently, the distribution opted for an adapted Gnome in the style of Ubuntu 20.04 , but that's it: In the future, desktops will only be included in the distribution in the vanilla version, adjustments are now left to the users. Intel announced last week that Linux desktops under Clear Linux do not want to add any other interfaces besides Gnome for the time being. They want to refocus on server- and cloudsystems.

Gnome as the standard desktop, KDE Plasma 5 and XFCE 4.14 are retained in the distribution and invite desktop users who are keen to experiment to try it out. High time to take a closer look at Clear Linux.

In the "Safe Installation", Clear Linux automatically recognizes an unpartitioned area on the data carrier and does not touch systems that have already been installed.

A toolchain and Linux kernel that are as up-to-date as possible should ensure the speed advantages highlighted by Intel. The source code always includes the special commits from Intel for the in-house hardware. The binaries are built either with the GCC 9 or Clang compilers, depending on which compiler delivers the higher performance-results in the individual case. Both always use the latest flags for Intel processors of the x86-64 architecture and, if in doubt, throw compatibility with older processors overboard. As usual with a rolling release, the program versions available at clearlinux.org are very fresh.

According to the overview of compatible hardware, Clear Linux runs on CPUs from the second Core-i generation (Sandy Bridge) and comparable processors from AMD. The specific minimum requirements list the command extensions Intel SSSE3, SSE 4.1, SSE 4.2 and Carry-less Multiplication (CLMUL). In addition, the installation of Clear Linux requires UEFI. An installed system is booted via the EFI boot loader or via systemd-boot. Grub 2 will not be installed.

After the installation, GDM starts Gnome 3.36 under Xorg, but optionally also provides Wayland on the login page. The first user created during the installation also has administrator privileges via "sudo", while logging in as root is not intended.

Fast, slim, different

In the test on an old Thinkpad T430s by the author of this article, Clear Linux felt fit for everyday tasks on the desktop after getting used to the way software is handled.

The distribution does not hide its origin as a container operating system. The configuration of the system follows the "stateless" concept: The /etc directory is largely empty because bundles and system components keep their standard configuration elsewhere under /usr. A configuration file created under /etc is only used to override the standards, which has the advantage that deleting added settings always reactivates the standard configuration of a package.

When searching for programs, the graphical package management via Gnome software is less helpful than the tools in the command line, which quickly find usable installation candidates with "swupd-search". The localization of some programs outside of desktop bundles such as Gnome and KDE Plasma remains a problem. Due to the lack of packages, Clear Linux is not a universally applicable Linux system in the style of Debian, Ubuntu, Fedora or Arch Linux on the desktop.

In the benchmark test

In order to determine comparable benchmarks on the same hardware between different Linux distributions and Clear Linux, the author of this report used selected tests from the Phoronix Test Suite , especially since this is also packaged in Clear Linux. Clear Linux competed against Fedora 32 Workstation and against Ubuntu 20.04. Series of tests for Gimp October 2, 2018 show that all systems are close to one another in terms of performance.

In the other, synthetic benchmarks of SciMark 2 and Himeno 3.0, Clear Linux was only able to clearly stand out in the measured CPU performance of SciMark 2 (single core), while Ubuntu 20.04 in the beta version in the CPU performance tests of Himeno 3.0 (multicore ) is in front. Ubuntu 20.04 also set itself apart as a web server with NGINX and static websites. Contrary to expectations, Clear Linux in the tested version 32650 could not get a clear lead over Ubuntu 20.04.

All distributions tested were close together here. Although Clear Linux is quick to respond subjectively to this application, there is no measurable benefit.

If you feel like trying Clear Linux for yourself, you can download the live system of the desktop edition as an ISO image from the Clear Linux website . A 22-slide presentation by the Clear Linux developers provides an initial overview of the special features of the distribution.

Tbh, not much to change. Google Translate got really good over the years. --Leo Navis (talk) 19:59, 31 August 2021 (UTC)

Benchmarks

Gimp: All distributions tested were close together here. Although Clear Linux seems quick to respond to this application subjectively, there is no measurable benefit.

Himeno 3.0: This CPU benchmark uses all available cores and determines it by solving the Poisson-equation. In addition to processor performance, cache usage and RAM throughput have an impact on the results.

Webserver NGINX with static websites: This benchmark from the Phoronix Test Suite determines how many requests a started NGINX instance can answer per second via the loopback interface.

Singlecore-performance: Here Clear Linux is clearly ahead on the Intel CPU. This selected CPU benchmark from SciMark 2 uses only one processor core for a continuous Fourier transformation of periodic signals.
