A Look At Linux Application Scaling Up To 128 Threads

Wed, 2018-10-10 21:34

Arriving last week in our Linux benchmarking lab was a dual EPYC server -- this Dell PowerEdge R7425 is a beast of a system with two AMD EPYC 7601 processors yielding a combined 64 cores / 128 threads, 512GB of RAM (16 x 32GB DDR4), and 20 x 500GB Samsung 860 EVO SSDs. There will be many interesting benchmarks from this server in the days and weeks ahead. For some initial measurements during the first few days of stress testing this 2U rack server, here is a look at how well various benchmarks/applications are scaling from two to 128 threads.

This article with these benchmarks is mainly intended for reference purposes for those curious how well different Linux workloads scale up to 128 threads with these multi-core benchmarks available via the Phoronix Test Suite and OpenBenchmarking.org. Tests were done with 2, 4, 8, 16, 32, and 64 cores enabled and then the default configuration of 64 threads plus SMT to yield 128 threads of jaw-dropping power.

Ubuntu: Ubuntu 18.10, Ubuntu in 'Smart' Cities, and Snaps in Numbers

Wed, 2018-10-10 21:17
  • Do You Plan to Upgrade to Ubuntu 18.10?

    Such closeness means — shock — it’s almost-very-nearly upgrade decision time for many of us!

    The question is are you the sort of Linux user who likes to run the latest and greatest that open source software has to offer? Or do you prefer to play it safe on the stable foundation of an LTS? Perhaps you’re entirely uncertain?!

  • Ubuntu 18.10 Adds Gallium Nine Support, Latest Mesa 18.2.2

    A couple of graphic-related tidbits ahead of next week’s Ubuntu 18.10 release that some of you might be interested to know about.

    First up, Mesa.

    A feature freeze exception was granted to allow Mesa 18.2.x series in to the Ubuntu 18.10 archives, with Mesa 18.2.2 specifically (i.e the latest update) now ready in the archives.

  • Digital signage: the face of the smart city revolution

    Crucially, this means selecting an operating system and a digital signage solution with strong safety capabilities. Ubuntu is a strong choice for a secure OS, in large part because it restricts outside access to key system files better than most competitors. This makes it more difficult for malware to access a system. Meanwhile, in the signage software space, Broadsign is the clear winner thanks to SOC II and ISAE3402 audits that guarantee stronger SaaS security than what is standard for online banking.

  • Snapistics – Snaps in numbers

    Actions speak louder than words. So do numbers. When we talk about snaps, we often focus on the application packages, and talk about their individual merits. However, a no less important – and interesting – facet is the collective numbers behind the scenes. They tell a compelling story for developers and users alike. They allow us to look back and piece together a puzzle of perception and adoption, and map them onto underlying factors, like the introduction of the new Ubuntu LTS release, the availability of popular software, and deliberate changes introduced to make snaps more robust and accessible.

    Indeed, how do people perceive snaps? How well accepted are snaps in software development circles? Today, we’d like to share some of these figures.

Games: Stationeers, Between the Stars, Off Grid, Mark of the Ninja: Remastered, Timespinner

Wed, 2018-10-10 19:52
  • RocketWerkz have confirmed their plans to do a Linux version of Stationeers

    A good bit of news to wake up to today! Stationeers a space station construction and management game from developer RocketWerkz should be coming to Linux.

    In their official FAQ on Steam, the developer noted that if it sold at least 300K copies a Linux version would be considered. Someone then made a post on Steam last year, full of users requesting a Linux version of Stationeers. Six pages of replies later, the developer replied a few hours ago with a link to this new post (also added to their FAQ now) confirming their intent to make a Linux version now.

  • Between the Stars looks like an incredible spaceship action game, coming to Linux

    Between the Stars, a spaceship action game with 'traces of RPG, management and roguelike elements' looks set to come to Linux.

  • Off Grid gives you data as your weapon in this stealth hacking game, now crowfunding with Linux support

    I covered this before briefly back in April, as the developer seemed committed to providing a Linux version. Sadly, the demo is currently only on Windows and Mac but I did speak to the developer today where they told me a Linux demo is now a priority with the Kickstarter being live. They've unfortunately had some last minute issues they're trying to solve, so hopefully it won't be long. Update: As the developer noted in our comments, the demo is now on itch.io.

  • Mark of the Ninja: Remastered is out on Steam with Linux support

    Mark of the Ninja: Remastered, the relatively small upgrade over the original is now out with Linux support on Steam.

    Unlike a lot of remasters, Mark of the Ninja: Remastered isn't actually that big of an upgrade overall. It does include enhanced visuals that are no longer compressed down to 720p as it supports up to 4K now. It also has improved character and background art proving some clearer details along with remastered cinematics. On top of that, there's also 5.1 audio support and the Special Edition DLC is also now included as standard.

  • Timespinner, the fun metroidvania is now available on GOG with a Linux build

    After the release on Steam late last month, Timespinner is now available DRM free on GOG for more of you to go exploring. They have the latest patch build too with a couple of bug fixes. Note: Key provided by GOG.

​Cloud Foundry embraces Kubernetes

Wed, 2018-10-10 19:44

Cloud Foundry, a prominent open-source Platform-as-a-Service (PaaS) cloud, isn't giving up on BOSH its tool chain for release engineering, deployment, and life-cycle management of large scale distributed services. But Cloud Foundry is making it easier to use Kubernetes both independently and as part of BOSH.

The Cloud Foundry Foundation is doing this by accepting two new projects: Eirini and CF Containerization. This comes after last year's adoption of Cloud Foundry Container Runtime (CFCR), which started Cloud Foundry's integration of Kubernetes. CRCR makes it possible to deploy and manage Kubernetes clusters using the BOSH release engineering tool chain.

GNU: GNU Guix, GNU Guile, Parabola GNU/Linux-libre

Wed, 2018-10-10 19:18
  • GNU Guix: A packaging tutorial for Guix

    GNU Guix stands out as the hackable package manager, mostly because it uses GNU Guile, a powerful high-level programming language, one of the Scheme dialects from the Lisp family.

    Package definitions are also written in Scheme, which empowers Guix in some very unique ways, unlike most other package managers that use shell scripts or simple languages.

  • GNU Guile 2.9.1 (beta) released

    We are delighted to announce GNU Guile 2.9.1, the first beta release in preparation for the upcoming 3.0 stable series.

    This release adds support for just-in-time (JIT) native code generation, speeding up all Guile programs. Currently support is limited to x86-64 platforms, but will expand to all architectures supported by GNU Lightning.

  • Parabola GNU/Linux-libre: Important notice for OpenRC users on i686

    To avoid any trouble, you should explicitly install the 'audit' package before attempting to upgrade the system. If you upgrade without first installing the 'audit' package, then you will need to chroot into the system and install it.

Red Hat Converges CoreOS Features In OpenShift Container Platform 3.11

Wed, 2018-10-10 19:14

Red Hat announced the general availability of its OpenShift Container Platform 3.11 release on Oct. 10, providing organizations with new capabilities for managing cloud native Kubernetes deployments.

Among the key highlights of the OpenShift Container Platform 3.11 release are multiple components that have been integrated from the CoreOS Tectonic distribution of Kubernetes, including a new cluster administrator console. Red Hat has also integrated CoreOS' Operator concept into OpenShift making it easier for organizations to deploy cloud native applications.

"This is the initial release for us to deliver on our converged roadmap that we announced at Red Hat Summit earlier this year," Brian Gracely, director, Product Strategy, OpenShift, at Red Hat, told eWEEK. "There are three primary feature sets that come into OpenShift 3.11 from the CoreOS acquisition."

GNOME Plans to Retire Application Menus from the GNOME 3.32 Desktop Environment

Wed, 2018-10-10 19:01

With the recent release of the GNOME 3.30 "Almería" desktop environment, which already got its first point release and hit the stable repositories of some of the major GNU/Linux distributions, GNOME 3.32 "Taipei" has now entered development and the first milestone should hit the testing channels later this week.

We don't know much about the new features and improvements coming to the GNOME 3.32 desktop environment, due for release next year on March 13, 2019, but it looks like one existing feature won't be available anymore in this upcoming release, as developer Allan Day announced the deprecation of application menus.

CentOS 6 and RHEL 6 Get Important Kernel Security Update for FragmentSmack Flaw

Wed, 2018-10-10 18:59

According to the RHSA-2018:2846 and CESA-2018:2846 security advisories, the new kernel security update is marked as "Important" by Red Hat's security team as it patches two security vulnerabilities (CVE-2018-5391 and CVE-2018-14634) discovered in the Linux kernel packages for the Red Hat Enterprise Linux 6 and CentOS Linux 6 operating system series.

The first security flaw addressed in this important kernel update is CVE-2018-5391, a security vulnerability known as FragmentSmack and discovered in the way Linux kernel handled reassembly of fragmented IPv6 and IPv4 packets, which could allow a remote attacker to cause a denial of service on the vulnerable systems by sending specially crafted packets, leading to a CPU saturation.

Security: G+, SSH, GAO, Flatpak, Telecommunications (Interception and Access) Act 'Extended', More on China's Alleged Supply Chain Attacks

Wed, 2018-10-10 18:52
  • Pete Zaitcev: Ding-dong, the witch is dead

    One thing that comes across very strongly is how reluctant people are to run their own infrastructure. For one thing, the danger of a devastating DDoS is absolutely real. And then you have to deal with spam. Those who do not have the experience also tend to over-estimate the amount of effort you have to put into running "dnf update" once in a while.

    Personally, I think that although of course it's annoying, the time wasted on the infra is not that great, or at least it wasn't for me. The spam can be kept under control with a minimal effort. Or, could be addressed in drastic ways. For example, my anime blog simply does not have comments at all. As far as DoS goes, yes, it's a lottery. But then the silo platform can easily die (like G+), or ban you. This actually happens a lot more than those hiding their heads in the sand like to admit. And you don't need to go as far as to admit to your support of President Trump in order to get banned. Anything can trigger it, and the same crazies that DoS you will also try to deplatform you.

  • (SSH) Keys to Unix Security

    Root accounts are the keys to powerful IT systems, the backbone of your entire infrastructure. They use privileged credentials to control shell access, file transfers, or batch jobs that communicate with other computers or apps, often accessed remotely, with local configuration. They can be the trickiest of all types of privileged accounts to secure, particularly if they are based on Unix or Linux.

  • Cyber Tests Showed 'Nearly All' New Pentagon Weapons Vulnerable To Attack, GAO Says [iophk: "Windows TCO"]

    Still, the tests cited in the report found "widespread examples of weaknesses in each of the four security objectives that cybersecurity tests normally examine: protect, detect, respond, and recover."

    [...]

    In several instances, simply scanning the weapons' computer systems caused parts of them to shut down.

    [...]

    When problems were identified, they were often left unresolved. The GAO cites a test report in which only one of 20 vulnerabilities that were previously found had been addressed. When asked why all of the problems had not been fixed, "program officials said they had identified a solution, but for some reason it had not been implemented. They attributed it to contractor error," the GAO says.

  • Flatpak - a security nightmare

    Let's hope not! Sadly, it's obvious Red Hat developers working on flatpak do not care about security, yet the self-proclaimed goal is to replace desktop application distribution - a cornerstone of linux security.

    And it's not only about these security problems. Running KDE apps in fakepak? Forget about desktop integration (not even font size). Need to input Chinese/Japanese/Korean characters? Forget about that too - fcitx has been broken since flatpak 1.0, never fixed since.

    The way we package and distribute desktop applications on Linux surely needs to be rethinked, sadly flatpak is introducing more problems than it is solving.

  • Encryption bill will hit family violence victims: claim

    In a submission to the public consolation on the draft bill, Carolyn Worth, the manager of SECASA, said the broadening of the Telecommunications (Interception and Access) Act 1979 was unwarranted and would be detrimental to all citizens, especially those with a background of family violence and/or sexual assault.

    The period for public comment on the bill, which is officially known as the Telecommunications and Other Legislation Amendment (Assistance and Access) Bill 2018, ended on 10 September after the draft was released on 14 August.

  • Bloomberg says big US telco hit by hardware tampering

    Apparently undeterred by strong criticism of a supply chain attack story it published last week, Bloomberg has put out another yarn, dealing with a similar theme, this time about a "major US telecommunications company" that allegedly encountered doctored hardware made by the US company Supermicro Computer.

  • RiskIQ Detects and Mitigates New Magecart Supply Chain Attack

"Many payment service providers have already taken this approach by prohibiting third-party code from running on pages where customers enter their payment information."

Linux-Based Airtame 2 Offers an Enterprise Alternative to Chromecast

Wed, 2018-10-10 18:51

One category that often gets overlooked in the discussion of Linux computers is the market for HDMI dongle devices that plug into your TV to stream, mirror, or cast content from your laptop or mobile device. Yesterday, Google announced an extensively leaked third-gen version of its market-leading, Linux-powered Chromecast device. The latest Chromecast upgrades the WiFi radio to 5GHz and adds 2.4GHz Bluetooth while also overhauling the physical design.

Here, we look at a similar Linux-based HDMI dongle device that launched this morning with a somewhat different feature set and market focus. The Airtame 2 is the first hardware overhaul since the original Airtame generated $1.3 million on Indiegogo in 2013. The new version doubles the RAM, improves the Debian Linux firmware, and advances to dual-band 802.11a/b/g/n/ac, which is now known as WiFi 5 in the new Wi-Fi Alliance naming scheme that accompanied its recent WiFi 6 (ax) announcement.

New Manjaro Beta Builds a Better Arch

Wed, 2018-10-10 18:47

Regardless of which desktop you select, the welcome screen introduces Manjaro tools and get-acquainted details such as documentation, support tips, and links to the project site.

You can get a full experience in using the live session ISOs without making any changes to the computer's hard drive. That is another advantage to running Manjaro Linux over a true Arch distro. Arch distros usually do not provide live session environments. Most that do lack any automatic installation launcher from within the live session.

Caution: When you attempt to run the boot menu from the Manjaro DVD, pay attention to the startup menu. It is a bit confusing. To start the live session, go halfway down the list of loading choices to select the Boot Manjaro option. The other menu options let you configure non-default choices for keyboard, language, etc.

After the live medium loads the Manjaro live session, browse the categories in the welcome window. You can click the Launch Installer button in the welcome window or launch it after experiencing the live session by clicking on the desktop install icon or running the installation program from the main menu.

Installation is a simple and straightforward process. The Calamares installer allows newcomers to easily set up the distro. It gives advanced users lots of customization options.

Linux-driven LoRaWAN gateway ships with new “Wzzard” LoRa nodes

Wed, 2018-10-10 18:45

Advantech has launched a rugged, Arm Linux based “WISE-6610” LoRaWAN gateway in 100- or 500-node versions with either 915MHz or 868MHz support. There’s also a “Wzzard LRPv2 Node” that can connect four sensors at once.

Advantech announced the industrial WISE-6610 gateway and Wzzard LRPv2 Node for long-range, low-bandwidth LoRaWAN gateways on May 31, and judging from this Oct. 5 Electronics Weekly post, they are now available. Designed for I/O sensor data management and network protocol conversion primarily on private LoRaWAN networks, the products are part of a Wzzard LoRa Sensing Network family that includes a recent SmartSwarm 243 gateway that appears to be almost identical to the WISE-6610 (see farther below).

An introduction to using tcpdump at the Linux command line

Wed, 2018-10-10 11:15

Tcpdump is a command line utility that allows you to capture and analyze network traffic going through your system. It is often used to help troubleshoot network issues, as well as a security tool.

A powerful and versatile tool that includes many options and filters, tcpdump can be used in a variety of cases. Since it's a command line tool, it is ideal to run in remote servers or devices for which a GUI is not available, to collect data that can be analyzed later. It can also be launched in the background or as a scheduled job using tools like cron.

In this article, we'll look at some of tcpdump's most common features.

  • Fedora at LinuxDays 2018 in Prague

    LinuxDays, the biggest Linux event in the Czech Republic, took place at the Faculty of Information Technology of Czech Technical University in Prague. The number of registered attendees was a bit lower this year, it could be caused by municipality and senate elections happening on Fri and Sat, but the number got almost to the 1300 mark anyway.

    Besides a busy schedule of talks and workshops the conference also has a pretty large booth area and as every year I organized the Fedora one. I drove by car to Prague with Carlos Soriano and Felipe Borges from the Red Hat desktop team on Saturday morning and we were joined by František Zatloukal (Fedora QA) at the booth.
