Linux 3.5 Through Linux 4.4 Kernel Benchmarks: A 19-Way Kernel Showdown Shows Some Regressions

Filed under

Linux

What better way to spend a cold Friday morning than looking at some kernel benchmarks, so up for your viewing pleasure today are benchmarks of every kernel major release going from the Linux 3.5 kernel up through the latest Linux 4.4 stable kernel release. All the tests were done on the same system and there are actually some interesting performance changes to note with these Linux kernel tests going back to the summer of 2012.

The system I used this week for carrying out this Linux 3.5 to Linux 4.4 kernel comparison was the Xeon E5-2687W v3 Haswell processor (10 cores plus Hyper Threading), MSI X99S SLI PLUS motherboard, 16GB of DDR4 memory, a PNY CS121 120GB solid-state drive, and AMD FirePro V7900 (Cayman) graphics card. All of the hardware was maintained the same throughout testing and each kernel was tested with its defaults as obtained from the Ubuntu Mainline Kernel PPA archive; so you can fetch from there if you are curious about any of the Kconfig and other defaults.

Flatpak 1.0 Linux Application Sandboxing & Distribution Framework Is Almost Here

While it's becoming very popular among Linux users as it is more and more adopted by Linux OS vendors, Flatpak is still considered an "under development" technology, and so it's not yet promoted on a mass scale as its rival Snap is by Ubuntu's mother company Canonical. However, Flatpak as it is right now, it's very usable, but it is yet to achieve the 1.0 version milestone, which usually marks a project as mature and ready for mass deployment. And it's now more closer than ever as the development team announced today the availability of the first Flatpak 1.0 pre-release version.

6 Open Source AI Tools to Know

In open source, no matter how original your own idea seems, it is always wise to see if someone else has already executed the concept. For organizations and individuals interested in leveraging the growing power of artificial intelligence (AI), many of the best tools are not only free and open source, but, in many cases, have already been hardened and tested. At leading companies and non-profit organizations, AI is a huge priority, and many of these companies and organizations are open sourcing valuable tools. Here is a sampling of free, open source AI tools available to anyone. Read more

Skylake module aces OSADL’s real-time Linux tests

Congatec has joined the Open Source Automation Development Lab, which has certified that the real-time Linux stack for the Skylake Xeon-E3 based Conga-TS170 COM Express module offers “excellent response times.” The Open Source Automation Development Lab (OSADL) has certified Congatec’s implementation of real-time Linux (RTL), and has accepted Congatec as a member.
