  • The Anticipated Linux Driver Requirements For The Radeon Instinct MI50 / MI60 (Vega 20)

    With this week's announcement of the Radeon Instinct MI60 and MI50 as what we previously knew as Vega 20, here's a look at what is likely required from the Linux software side for making use of these professional GPUs that will begin shipping in early 2019.

  • AMD Lands Big Batch Of AMDVLK Vulkan Driver Changes To Start November

    As it had been two weeks since AMD developers last pushed out new source updates to their AMDVLK Vulkan Linux driver, rather than their normal weekly release cadence, today's driver updates are a bit on the heavier side than some of their past light updates.

  • NVIDIA 415.13 Beta Linux Graphics Driver Released With Assorted Improvements

    NVIDIA today released their first beta release for Linux/Solaris/BSD users in the 415 release stream.

    NVIDIA 415.13 is now the first post-410 series driver for Linux users. That 410 driver series was big for introducing NVIDIA RTX "Turing" graphics card support and initial Vulkan ray-tracing support. The NVIDIA 415 driver isn't as significant but has various fixes and improvements throughout its large driver stack.

  • More AMD Zen Microarchitecture Tuning For Mesa Is Likely Ahead

    Published back in September was some Mesa RadeonSI tuning for AMD Zen CPUs. That tuning to pin the application thread and driver execution thread to the same L3 cache benefits the Zen micro-architecture with its multiple core complexes (CCX). That code was merged a short time later unconditionally but it looks like that behavior needs to be refined for delivering maximum performance.

Canonical Extends Ubuntu 18.04 LTS Linux Support to 10 Years

BERLIN — In a keynote at the OpenStack Summit here, Mark Shuttleworth, founder and CEO of Canonical Inc and Ubuntu, detailed the progress made by his Linux distribution in the cloud and announced new extended support. The Ubuntu 18.04 LTS (Long Term Support) debuted back on April 26, providing new server and cloud capabilities. An LTS release comes with five year of support, but during his keynote Shuttleworth announced that 18.04 would have support that is available for up to 10 years. "I'm delighted to announce that Ubuntu 18.04 will be supported for a full 10 years," Shuttleworth said. "In part because of the very long time horizons in some of industries like financial services and telecommunications but also from IOT where manufacturing lines for example are being deployed that will be in production for at least a decade ."

Benchmarking Packet.com's Bare Metal Intel Xeon / AMD EPYC Cloud

With the tests earlier this week of the 16-way AMD EPYC cloud comparison the real standout of those tests across Amazon EC2, Packet, and SkySilk was Packet's bare metal cloud. For just $1.00 USD per hour it's possible to have bare metal access to an AMD EPYC 7401P 24-core / 48-thread server that offers incredible value compared to the other public cloud options for on-demand pricing. That led me to running some more benchmarks of Packet.com's other bare metal cloud options to see how the Intel Xeon and AMD EPYC options compare. Packet's on-demand server options for their "bare metal cloud" offerings range from an Intel Atom C2550 quad-core server with 8GB of RAM at just 7 cents per hour up to a dual Xeon Gold 6120 server with 28 cores at two dollars per hour with 384GB of RAM and 3.2TB of NVMe storage. There are also higher-end instances including NVIDIA GPUs but those are on a dynamic spot pricing basis. Read more

Programming: WebRender, Healthcare Design Studio GoInvo, PHP Boost and Google Cloud Platform (GCP)

  • Mozilla GFX: WebRender newsletter #30
    Hi! This is the 30th issue of WebRender’s most famous newsletter. At the top of each newsletter I try to dedicate a few paragraphs to some historical/technical details of the project. Today I’ll write about blob images. WebRender currently doesn’t support the full set of graphics primitives required to render all web pages. The focus so far has been on doing a good job of rendering the most common elements and providing a fall-back for the rest. We call this fall-back mechanism “blob images”. The general idea is that when we encounter unsupported primitives during displaylist building we create an image object and instead of backing it with pixel data or a texture handle, we assign it a serialized list of drawing commands (the blob). For WebRender, blobs are just opaque buffers of bytes and a handler object is provided by the embedder (Gecko in our case) to turn this opaque buffer into actual pixels that can be used as regular images by the rest of the rendering pipeline.
  • Healthcare Design Studio GoInvo Releases Open Source Research on Loneliness [Ed: Very odd if not 'creative' use of the term Open Source]
  • PHP Lands Preload Feature, Boosting Performance In Some Cases 30~50%
    PHP developers unanimously approved and already merged support for the new "preloading" concept for this web server language. PHP preloading basically allows loading PHP code that persists as long as the web server is running and that code will always be ready for each subsequent web request, which in some cases will dramatically speed-up the PHP performance on web servers. While PHP has long supported caching to avoid PHP code recompilation on each new web request, with each request PHP has still had to check to see if any of the source file(s) were modified, re-link class dependencies, and similar work. PHP preloading allows for given functions/classes to be "preloaded" that will survive as long as the web server is active. It effectively allows loading of functions or entire/partial frameworks that will then be present for each new web request just as if it were a built-in function.
  • Google Announces a Managed Cron Service: Google Cloud Scheduler
    Google announced a new Service on the Google Cloud Platform (GCP) - Cloud Scheduler, a fully managed cron job service that allows any application to invoke batch, big data and cloud infrastructure operations. The service is currently available in beta. With Google Cloud Scheduler customers can use the cron service with no need to manage the underlying infrastructure. There is also no need to manually intervene in the event of transient failure, as the services retries failed jobs. Furthermore, customers will only pay for the operations they run -- GCP takes care of all resource provisioning, replication and scaling required to operate Cloud Scheduler. Also, customers can, according to Vinod Ramachandran, product manager at Google, benefit from:
