Benchmarking OpenMandriva's AMD Ryzen Optimized Linux Distribution On The Threadripper 3970X

While Clear Linux is well known as being the performance-optimized Linux distribution out of Intel and catered towards performing the best on their hardware (though as we continue to show, Clear Linux does also perform incredibly well on AMD hardware too and generally faster than other distributions), when it comes to AMD-optimized distributions the primary example remains OpenMandriva. Since 2018 OpenMandriva has been providing an AMD Zen optimized build where their operating system and entire package archive is built with the "znver1" compiler optimizations. As it's been almost a year since last looking at OpenMandriva's Zen optimized build, here are some fresh benchmarks using the newly-released OpenMandriva 4.1.

FreeBSD vs. Linux Scaling Up To 128 Threads With The AMD Ryzen Threadripper 3990X

Last week I looked at the Windows vs. Linux scaling performance on the Threadripper 3990X at varying core/thread counts followed by looking at the Windows 10 performance against eight Linux distributions for this $3990 USD processor running within the System76 Thelio Major workstation. Now the tables have turned for our first look at this 64-core / 128-thread processor running on the BSDs, FreeBSD 12.1 in particular. With this article is looking at the FreeBSD 12.1 performance and seeing how the performance scales compared to Ubuntu 20.04 Linux and the Red Hat Enterprise Linux 8 based CentOS Stream.

NVIDIA Posts Firmware Needed For Open-Source GeForce 16 Series Acceleration

As written about last week, in the works for the Linux 5.7 kernel this spring is open-source NVIDIA "Nouveau" acceleration for the GeForce 16 series. That code is currently sitting in the Nouveau development tree until landing in DRM-Next for Linux 5.7, but NVIDIA has now posted the necessary firmware binaries needed for enabling the hardware acceleration on these Turing GPUs.

AMD Announces EPYC 7532 + EPYC 7662 As Newest Rome Processors

AMD has expanded their 7002 series "Rome" family with the availability today of the EPYC 7662 as their latest 64-core / 128-thread offering and the EPYC 7532 as a new 32-core part but with a full 256MB cache to offer more per-core L3 cache than other 32-core processors.

LLVM Clang 11 Adds -std=c++20 Support

With C++20 now being deemed complete from the recent ISO C++ meeting in Prague, the GNU Compiler Collection went ahead and added the -std=c++20 flag where as up until that change this weekend relied upon the -std=c++2a switch. LLVM's Clang compiler now has similar treatment on its codebase.

Intel Sends Out Latest Patches For Mitigating Graphics Flaw On Ivybridge/Haswell

It has been one month and a few days since Intel first made public the need for graphics driver patching of Gen 7/7.5 graphics for older Ivybridge / Haswell hardware to fix a graphics hardware flaw. That vulnerability also affected the common Intel Gen9 graphics but there the mitigation was uneventful and quickly merged without causing any performance hit. But for Ivybridge/Haswell one month later the graphics driver mitigation for CVE-2019-14615 is still being addressed.

D-Bus Broker 22 Released With Option To Use Newer Kernel Features

With BUS1 not looking like it will come to fruition anytime soon as an in-kernel IPC mechanism and the kernel module for it not being touched since last March, the same developers continue pushing ahead with Dbus-Broker as the user-space implementation focused on D-Bus compatibility while being higher performing and more reliable than D-Bus itself.
