AMD Ryzen DDR4 Memory Scaling Tests On Linux

35 min 32 sec ago

This week MSI finally released an updated BIOS for the X370 XPOWER GAMING TITANIUM that we've been using for a majority of our Ryzen Linux benchmarks. With that motherboard improving memory compatibility and allowing us to finally run the board at higher DDR4 memory clock frequencies, I've run some fresh AMD Ryzen 7 1800X Ubuntu Linux benchmarks at various memory frequencies.

  • GCC for New Contributors

    I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC. Hence this guide.

  • #1: Easy Package Registration

    Last month, Brian Ripley announced on r-devel that registration of routines would now be tested for by R CMD check in r-devel (which by next month will become R 3.4.0). A NOTE will be issued now, this will presumably turn into a WARNING at some point. Writing R Extensions has an updated introduction) of the topic.

  • Emacs as C IDE and JHBuild

    Although Builder clearly is The Future as GNOME IDE, I still all my coding in Emacs, mostly because I have been using it for such a long time that my brain is to all the shortcuts and workflows. But Emacs can be a good IDE too. The most obvious everyday features that I want from an IDE are good source code navigation and active assistance while editing. In the first category are tasks like jumping to symbol's definition, find all callers of a function and such things. For editing, auto-completion, immediate warnings and error reporting, semantic-aware re-factoring are a must. Specifically for GNOME related development, I need all this to also work with JHBuild.

  • Security updates for Wednesday
  • Cisco learned from Wikileaks that the CIA had hacked its systems

    When WikiLeaks founder Julian Assange disclosed earlier this month that his anti-secrecy group had obtained CIA tools for hacking into technology products made by U.S. companies, security engineers at Cisco Systems swung into action.

    The Wikileaks documents described how the Central Intelligence Agency had learned more than a year ago how to exploit flaws in Cisco's widely used Internet switches, which direct electronic traffic, to enable eavesdropping.

  • Exposed files on Microsoft's document-sharing site

    Confidential documents, passwords and health data have been inadvertently shared by firms using Microsoft's Office 365 service, say researchers.

    The sensitive information was found via a publicly available search engine that is part of Office 365.

    Security researchers said many firms mistakenly thought documents would only be shared with colleagues not globally.

    Microsoft said it would "take steps" to change the service and remove the sensitive data.

It is entirely possible to use open source in a highly regulated environment such as air traffic control, says Dr Gerolf Ziegenhain, Head of Linux Competence & Service Centre (LCSC) in Mainz (Germany).

  • DRM display resource leasing (kernel side)

    So, you've got a fine head-mounted display and want to explore the delights of virtual reality. Right now, on Linux, that means getting the window system to cooperate because the window system is the DRM master and holds sole access to all display resources. So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work.

  • GUADEC accommodation

    At this year’s GUADEC in Manchester we have rooms available for you right at the venue in lovely modern student townhouses. As I write this there are still some available to book along with your registration. In a couple of days we have to a final numbers to the University for how many rooms we want, so it would help us out if all the folk who want a room there could register and book one now if you haven’t already done so! We’ll have some available for later booking but we have to pay up front for them now so we can’t reserve too many.

  • How To Improve The Linux System’s Security Using Firejail

    As you already know, Linux kernel is secure by default. But, it doesn’t mean that the softwares on the Linux system are completely secure. Say for example, there is a possibility that any add-ons on your web browser may cause some serious security issues. While doing financial transactions over internet, some key logger may be active in browser which you are not aware of. Even though, we can’t completely give the bullet-proof security to our Linux box, we still can add an extra pinch of security using an application called Firejail. It is a security utility which can sandbox any such application and let it to run in a controlled environment. To put this simply, Firejail is a SUID (Set owner User ID up on execution) program that reduces the risk of security breaches by restricting the running environment of untrusted applications.
