A Look At The Changes & New Features Of GNOME 3.24

With GNOME 3.24 due to be released next week, I've spent some time trying out the latest, near-final packages using Fedora Rawhide. The experience has been good and from my initial impressions it appears to be another reliable update to the GNOME Shell experience. Here are some screenshots and a recap of the new features and changes for this six-month update to this open-source desktop environment.

The New Features Of The Linux 4.11 Kernel

If all goes according to plan, Linus Torvalds will have announced the first release candidate of the upcoming Linux 4.11 kernel before the day is through. The Linux 4.11-rc1 release also marks the end of the feature merge window for this kernel cycle. So with that said, here is a look at the new features of the Linux 4.11 kernel that I have been covering through closely watching the Git repository and mailing list over the past two weeks.

Benchmarking OpenCL On Intel Graphics With Beignet 1.3

Last week marked the release of Intel's Beignet 1.3, their open-source project implementing OpenCL acceleration atop modern CPUs with HD/Iris Graphics. Significant with Beignet 1.3 is that they've finally implemented OpenCL 2.0 support! OpenCL 2.0 is now available for Skylake hardware and newer. Beignet 1.3 also has other new features, runtime improvements, LLVM 3.9 support, new extensions, and much more. Thus time for some benchmarking of this new Beignet release.

Linux Distributions vs. BSDs With netperf & iperf3 Network Performance

With now having netperf in the Phoronix Test Suite as well as iperf3 for the latest open-source benchmarks in our automated cross-platform benchmarking framework, I couldn't help but to run some networking benchmarks on a system when trying out a few different Linux distributions and BSDs to see how the performance compares. The operating systems ran with these networking benchmarks included Debian 8.6, Ubuntu 16.10, Clear Linux 12020, CentOS 7, and Fedora 25. The BSDs tested for this comparison were FreeBSD 11.0 and DragonFlyBSD 4.6.1.

Early Benchmarks Of GCC 7 On Linux x86_64 With An Intel Core i7 6800K

With the GCC 7 compiler having entered its stage three, feature development is basically over so it's a great time to begin running more benchmarks of this big compiler update that will be officially released as GCC 7.1.0 in early 2017. Up today are benchmarks of the latest GCC 7.0 development snapshot compared to GCC 6.2 and GCC 5.4 on an Intel Core i7 6800K Broadwell-E system running Ubuntu 16.10.

20-Way NVIDIA/AMD GPU Darktable OpenCL Photography Performance

With the holiday season in full swing, whether you are just a casual photographer or professional, Darktable is easily one of the best photography workflow applications and it's free software! Darktable has offered OpenCL acceleration for providing faster performance on GPUs and with the imminent Darktable 2.2 release there is even better OpenCL results. For those curious about the OpenCL performance of Darktable, I've done some Darktable 2.2-RC1 benchmarks on a variety of NVIDIA GeForce and AMD Radeon graphics cards under Ubuntu Linux.

Power Consumption & Efficiency Of The Linux Kernel For The Last Three Years

Earlier this week I published Linux 3.9 through Linux 4.9 kernel benchmarks looking at the raw performance of various subsystems when testing each of the major kernel releases as far back as this Core i7 Haswell system was supported. From that same system, today is a look at testing the kernels going back to Linux 3.11 when Haswell graphics support was first in good shape for this Core i7 4790K box while looking at the raw power consumption and performance-per-Watt for these 19 major kernel releases.
