Microsoft Windows Server Benchmarked Against Six Linux Distributions

While it was not too long ago that Microsoft Windows Server 2019 began shipping and that we conducted some end-of-year benchmarks between Windows and Linux, with being in the process of running a number of Windows and Linux benchmarks as part of our ongoing 10GbE OS performance testing, I also took the opportunity to run some other benchmarks on Windows Server 2016 and 2019 as well as a set of Linux distributions.

The LLVM Codebase Is Moving Past C++11 This Year, Likely To C++14

As was discussed in 2018 and has largely reached consensus, the LLVM code-base and its sub-projects like Clang will move past being bound by C++11 and will moving to a newer C++ standard so they can begin making use of newer language features in the development of this compiler stack.

Open-Source Linux Driver Published For Habana Labs' "Goya" AI Processor

Habana Labs is one of the companies working on an "AI" processor for speeding up deep learning inference and training workloads. Their initial product is the Goya processor that is already production-qualified. Today they published initial open-source Linux kernel driver patches for review to potentially include in the mainline kernel moving forward.

Qt 5.13 Slated To Deliver Many WebAssembly Improvements

The Qt 5.12 release at the end of last year brought the Qt for WebAssembly Tech Preview to allow for Qt-based applications to run within web browsers via the sandboxed WASM technology. With the Qt 5.13 release coming out this spring, the WebAssembly support should be in much better shape.

Read-Only Apple File-System Support Is Being Worked On For The Linux Kernel (APFS)

The past few years Apple has been developing APFS as the successor to the long-used HFS+ file-system. The Apple File-System is in use with macOS 10.13+ iOS 10.3, and their other platforms for offering a lot of features not found in HFS+ including much better performance. There is an open-source APFS kernel driver now under development for Linux in supporting this file-system.

Fedora 30 Going Through Its Formalities To Ship With & Built By The GCC 9 Compiler

With each new Fedora release you can pretty much be guaranteed it will be using the latest and greatest releases of the GNOME desktop, the most recent stable kernel, and it's also been very punctual in switching over to new major releases of the GCC compiler -- generally being the first of the major Linux distributions adopting the annual major GNU compiler releases. With Fedora 30 due out in May, it should ship with GCC 9.1 as would be standard practice. It's not guaranteed though as FESCo hasn't signed off on it with this change request coming in past the deadline.

Mesa 18.2 vs. 18.3 vs. 19.0 January Benchmarks For RadeonSI/RADV

With Mesa 19.0 entering its feature freeze before the month is through, here are fresh benchmarks of the very latest RadeonSI OpenGL and RADV Vulkan performance on Polaris and Vega graphics cards compared to the current stable Mesa 18.3 series and the former 18.2 release. This testing is complementary to last week's Mesa 19.0 RADV vs. AMDVLK vs. AMDGPU-PRO Vulkan tests.

Some Radeon ROCm Packages Pending Review For Fedora

Earlier this month was word that Fedora developers were looking at packaging Radeon Open Compute (ROCm) to make it easier for their distribution users to enjoy this open-source Radeon GPU computing software from OpenCL to a TensorFlow port. Some of the early packages of ROCm are now under review for Fedora.

There's Early Stage Work Exploring Z-Wave Linux Kernel Drivers

Z-Wave is the incredibly common wireless communication protocol at the backbone of many home automation systems. To date there hasn't been any in-kernel Z-Wave Linux kernel drivers for this low-energy mesh network standard, but a SUSE developer has prototyped an initial driver and currently exploring the in-kernel possibilities, including what could end up being a Z-Wave subsystem.

PortableCL Continues Marching Towards The POCL 1.3 Release

When it comes to being able to run OpenCL kernels on CPUs, the main option at this point for Linux systems is POCL as the Portable Computing Language. While POCL 1.2 was released just this past September, we're still very much looking forward to the upcoming POCL 1.3 release with more improvements for this portable OpenCL 1.2~2.0 implementation.

AMDGPU-PRO 18.50 vs. ROCm 2.0 OpenCL Performance

When recently publishing the PlaidML deep learning benchmarks and lczero chess neural network OpenCL tests, some Phoronix readers mentioned they were seeing vastly different results with using the PAL OpenCL driver in AMDGPU-PRO (Radeon Software) compared to using the ROCm compute stack. So for seeing how those two separate AMD OpenCL drivers compare, here are some benchmark results with a Vega GPU while testing ROCm 2.0 and AMDGPU-PRO 18.50.

NetBSD Exploring LLVM's LLD Linker For Lower Memory Footprint

The NetBSD project has been making good progress in utilizing the LLVM compiler stack not only for the Clang C/C++ compiler but also for the different sanitizers, the libc++ standard library for C++, and other improvements most of which are working their way into the upstream code-bases. One area of NetBSD's LLVM support being explored most recently is using the LLD linker.
