The Performance Impact To AMD Zen 2 Compiler Tuning On GCC 9 + Znver2

Thursday 11th of July 2019 02:28:00 PM
One of the areas that I always have "fun" benchmarking for new CPU launches is looking at the compiler performance. Following the recent Ryzen 3000 series launch I carried out some initial benchmarks looking at the current Zen 2 performance using the newest GCC 9 stable series with its "znver2" optimizations. Here is a look at how the Znver2 optimizations work out when running some benchmarks on the optimized binaries with a Ryzen 9 3900X running Ubuntu 18.04 LTS.

DebConf19 invites you to Debian Open Day at the Federal University of Technology - Paraná (UTFPR), in Curitiba

DebConf, the annual conference for Debian contributors and users interested in improving the Debian operating system, will be held in Federal University of Technology - Paraná (UTFPR) in Curitiba, Brazil, from July 21 to 28, 2019. The conference is preceded by DebCamp from July 14 to 19, and the DebConf19 Open Day on July 20. The Open Day, Saturday, 20 July, is targeted at the general public. Events of interest to a wider audience will be offered, ranging from topics specific to Debian to the greater Free Software community and maker movement. The event is a perfect opportunity for interested users to meet the Debian community, for Debian to broaden its community, and for the DebConf sponsors to increase their visibility. Less purely technical than the main conference schedule, the events on Open Day will cover a large range of topics from social and cultural issues to workshops and introductions to Debian. Read more

Sparky Linux 5.8

Today we are looking at Sparky Linux 5.8. This point release of Sparky 5 comes with LXQt 0.14.1, Debian Buster, Linux Kernel 4.19 and uses about 350MB of ram when idling. Sparky Linux LXQt has become one of my favorites, as it has a modern feeling, with the latest of Qt and the stability of Debian, makes it one great combination. Enjoy!

  • What?s next Sparky?

    As before, after releasing a new stable version of Sparky, there are a few changes to do. So… Sparky 4 “Tyche” is moved to oldstable line now. The latest 4.11 release is the last one of the 4 line, but it is still supported, the next 2 years about. Sparky 5 “Nibiru” just released, moving it from testing to stable line. The stable live/install media are available for i686, amd64 & armhf archs (the same as the older release).

  • Fedora announces the first preview release of Fedora CoreOS as an automatically updating Linux OS for containerized workloads

    Three days ago, Fedora announced the first preview release of the open-source project Fedora CoreOS as a secure and reliable host for computer clusters. It is specifically designed for running containerized workloads with automatic updates to the latest OS improvements, bug fixes, and security updates. It is secure, minimal, monolithic and is optimized for working with Kubernetes. The main goal of Fedora CoreOS is to be a reliable container host to run containerized workloads securely and at scale. It integrates Ignition from Container Linux technology and rpm-ostree and SELinux hardening from Project Atomic Host. Fedora CoreOS is expected to be a successor to Container Linux eventually. The Container Linux project will continue to be supported throughout 2019, leaving users with ample time to migrate and provide feedback. Fedora has also assured Container Linux users that continued support will be provided to them without any disruption. Fedora CoreOS will also become the successor to Fedora Atomic Host. The current plan is for Fedora Atomic Host to have at least a 29 version and 6 months of lifecycle.
