The Impact Of Switching To Linux 4.3 + Mesa-11.1/LLVM-3.8 On Ubuntu 15.10

Filed under
Graphics/Benchmarks

Yesterday I posted some performance results of a Radeon R9 290 tested on Ubuntu 15.04 and Ubuntu 15.10 out-of-the-box. In this article are some numbers when upgrading the Ubuntu 15.10 installation to use the non-standard Linux 4.3 Git kernel as well as Mesa 11.1-devel Git that's built against LLVM 3.8 SVN for the newest open-source AMD Linux experience.

DragonFlyBSD 4.2 vs. Ubuntu 15.10 CPU Performance

Filed under
Graphics/Benchmarks

In this article are benchmarks comparing the performance of DragonFlyBSD 4.2 to that of Ubuntu 15.10. With these CPU-focused benchmarks, the core scaling performance was also looked at in going from two cores through four cores plus Hyper Threading.

Processor utilization difference between IBM AIX and Linux on Power – apple to apple comparison

Filed under
Graphics/Benchmarks
Linux

The overall system-level processor utilization between AIX and Linux on Power for identical workload and Power hardware configurations in multicore SMT systems can't be compared because the calculations are completely different. The overall system-level processor utilization reported in Linux on Power is derived from /proc/stat, which is purely time based. Whereas, AIX is based on PURR and SPURR, which is more towards CAPEX planning and also projects more realistic and accurate processor utilization for the latest evolution of processors which has SMP and SMT environment. Actual performance difference between single threaded and SMT8 on POWER8 is 2.2 times. In time-based calculations, processor utilization report for a single thread projects as if each SMT thread and execution unit is independent of the other. This gives a notion that users can achieve eight times better performance in the SMT8 mode, which is not true in real world. The realistic 2.2 times processor utilization factor that is not accounted in the calculation is one of the reasons for the low processor utilization reported in Linux on Power system for certain workloads that do not utilize 100% core, when compared to the AIX on Power platform.

Liquorix Kernel Benchmarked Against Linux 4.2, Linux 4.3 Kernels

Filed under
Graphics/Benchmarks

Recently there were a number of requests about testing the latest state of Liquorix, the self-prcolaimed "better distro kernel" that is an optimized version of the Linux kernel with extra patches that makes it optimal for desktop, multimedia, and gaming workloads. Here's some fresh Liquorix vs. mainline Linux kernel performance benchmarks.

Wayland & Weston Compositor Ported To DragonFlyBSD

Filed under
Graphics/Benchmarks

Wayland has been ported to DragonFlyBSD along with its Weston compositor!

In the past we've seen some minor experiments by BSD developers with Wayland/Weston, but for the most part all of the BSDs are still focused on X.Org Server support -- need I remind Phoronix readers that DRM/KMS support is in varying stages across the BSD distributions too as one of the support stepping stones. Just a few days ago I ran into the DragonFly Radeon kernel module failing to properly mode-set with a several year old (pre-GCN) graphics card while meanwhile FreeBSD's Radeon KMS port worked. It's still rather a mine field when it comes to open-source graphics acceleration and support on the BSDs while slowly but surely their catching up with the kernel code.

NVIDIA + Nouveau: "Hopefully More Surprises To Come"

Filed under
Graphics/Benchmarks

Alexandre Courbot, a developer at NVIDIA who has been working on the Tegra open-source graphics support a lot for Nouveau, presented last week at LinuxCon Europe 2015.

Thanks to the work by Courbot and others at NVIDIA, the Tegra K1 with its Kepler GPU has mainline Nouveau graphics support while the open-source graphics enablement for the Tegra X1 with Maxwell GPU continues to be upstreamed.

FreeBSD/PC-BSD 10.2 vs. Ubuntu 15.04/15.10 Benchmarks

Filed under
Graphics/Benchmarks

It's been a while since last running any BSD vs. Linux benchmarks, so I've started some fresh comparisons using the latest releases of various BSDs and Linux distributions. First up, as for what's completed so far, is using the FreeBSD-based PC-BSD 10.2 compared to Ubuntu 15.04 stable and the latest development release of Ubuntu 15.10.

Leftovers: KDE

  • KDE's Project Neon Begins Publishing Daily Wayland Images
    KDE -- KDE's Project Neon has begun publishing daily images of the latest KDE Plasma stack powered atop Wayland rather than the X.Org Server. Jonathan Riddell passed along word that daily ISOs are now being spun of the freshest KDE development code with KWin acting as a Wayland compositor. The OS base is still Ubuntu 16.04 LTS.

Open source near ubiquitous in IoT, report finds

Open source is increasingly standard operating procedure in software, but nowhere is this more true than Internet of Things development. According to a new VisionMobile survey of 3,700 IoT developers, 91% of respondents use open source software in at least one area of their software stack. This is good news for IoT because only open source promises to reduce or eliminate the potential for lock-in imposed by proprietary “standards.” What’s perhaps most interesting in this affection for open source, however, is that even as enterprise developers have eschewed the politics of open source licensing, IoT developers seem to favor open source because “it’s free as in freedom.” Read more

Ubuntu 16.04 – My Experience so Far and Customization

While I earnestly anticipated the release of Unity 8 with Xenial Xerus (after watching a couple of videos that showcased its function), I was utterly disappointed that Canonical was going to further push its release — even though it was originally meant to debut with Ubuntu 14.04. Back to the point at hand, I immediately went ahead and installed Unity Tweak Tool, moved my dash to the bottom (very important) and then proceeded to replace Nautilus with the extensive Nemo file manager which is native to Linux Mint and by far superior to the former (my opinion).
