RadeonSI OpenGL vs. RADV Vulkan Performance For Mad Max

Filed under
Graphics/Benchmarks

Feral Interactive today released their first Linux ported game into public beta that features a Vulkan renderer. Mad Max on Linux now supports Vulkan and OpenGL, making for some fun driver/GPU benchmarking. Up first are some Radeon RX 480 and R9 Fury Vulkan vs. OpenGL benchmarks for Mad Max when using Mesa 17.1-dev Git.

AMD Ryzen DDR4 Memory Scaling Tests On Linux

Filed under
Graphics/Benchmarks

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.

  • Safety critical drawing with OpenGL SC

    Bringing software into a safety critical environment can be tricky, especially when using the complex APIs needed for modern 3D graphics. That’s what makes OpenGL SC (Safety Critical) so important: it bridges the gap between beautiful displays and functional safety, while trying to remain as close to existing embedded standards that we all know and love. OpenGL SC will only become more prevalent in embedded graphics work as industries increasingly try to merge safety conscious methodologies with user-friendly interfaces.

BSD

With DragonFlyBSD 4.8 making its debut yesterday, I was excited to give this updated BSD operating system a try now that it has UEFI support and some performance improvements. Here are some early benchmark results of DragonFlyBSD 4.8 compared to 4.6 and Intel's Clear Linux for some additional reference points.

  • Security Tips for Installing Linux on Your SysAdmin Workstation
    Once you’ve chosen a Linux distro that meets all the security guidelines set out in our last article, you’ll need to install the distro on your workstation.

  • Open-source developers targeted in sophisticated malware attack
    For the past few months, developers who publish their code on GitHub have been targeted in an attack campaign that uses a little-known but potent cyberespionage malware. The attacks started in January and consisted of malicious emails specifically crafted to attract the attention of developers, such as requests for help with development projects and offers of payment for custom programming jobs. The emails had .gz attachments that contained Word documents with malicious macro code attached. If allowed to execute, the macro code executed a PowerShell script that reached out to a remote server and downloaded a malware program known as Dimnie.
  • A scramble at Cisco exposes uncomfortable truths about U.S. cyber defense
    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 (CSCO.O) 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. Senior Cisco managers immediately reassigned staff from other projects to figure out how the CIA hacking tricks worked, so they could help customers patch their systems and prevent criminal hackers or spies from using the same methods, three employees told Reuters on condition of anonymity.
  • NTPsec: a Secure, Hardened NTP Implementation
    Network time synchronization—aligning your computer's clock to the same Universal Coordinated Time (UTC) that everyone else is using—is both necessary and a hard problem. Many internet protocols rely on being able to exchange UTC timestamps accurate to small tolerances, but the clock crystal in your computer drifts (its frequency varies by temperature), so it needs occasional adjustments. That's where life gets complicated. Sure, you can get another computer to tell you what time it thinks it is, but if you don't know how long that packet took to get to you, the report isn't very useful. On top of that, its clock might be broken—or lying. To get anywhere, you need to exchange packets with several computers that allow you to compare your notion of UTC with theirs, estimate network delays, apply statistical cluster analysis to the resulting inputs to get a plausible approximation of real UTC, and then adjust your local clock to it. Generally speaking, you can get sustained accuracy to on the close order of 10 milliseconds this way, although asymmetrical routing delays can make it much worse if you're in a bad neighborhood of the internet.

    I assume that every permutation of scams will eventually be tried; it is interesting that the initial ones preyed on people's avarice and dishonesty: "I will transfer millions to your bank account, then you share with me" - with subsequent scams appealing to another demographic: "I want to donate a large sum to your religious charity" - to perhaps capture a more virtuous but still credulous lot. Where will it end ?
