AMD EPYC On Ubuntu 18.10 Putting Up A Stronger Fight Against Xeon Gold

With hitting the home stretch to Ubuntu 18.10, I've started with my usual benchmark process for checking out this next Ubuntu Linux release dubbed the Cosmic Cuttlefish. Yesterday were Ubuntu 18.10 benchmarks on seven desktop systems from Intel and AMD while next on my agenda has been checking out the server performance. Here's the first of those server tests on Ubuntu 18.10 with some initial AMD EPYC and Intel Xeon Gold tests.

Google Open-Sources "GraphicsFuzz" For Helping To Spot GPU Driver Bugs

Remember GraphicsFuzz? That was the effort started by university students for fuzzing GPU drivers via WebGL in the browser and over the course of their research found various OpenGL driver bugs, including for mobile drivers. Last month the start-up born out of that university research was acquired by Google and now their work is open-source.

Ubuntu 18.10 Performance Is Looking Up, But Clear Linux Still Leads In Many Tests

With less than one month until Ubuntu 18.10 "Cosmic Cuttlefish" releases, I have begun my usual benchmarking dance in checking out how the Ubuntu performance is looking to its current release, in this case the Ubuntu 18.04 LTS "Bionic Beaver". Our first performance look at Ubuntu 18.10 is with a mix of seven Intel and AMD desktop systems while using Ubuntu 18.04 LTS with all updates, Ubuntu 18.10 in its current near-final form, and using Intel's Clear Linux as a gold standard reference with it generally offering the leading out-of-the-box Linux x86_64 performance of major distributions.
