"Nest" Is An Interesting New Take On Linux Kernel Scheduling For Better CPU Performance

Phoronix - Thu, 09/15/2022 - 18:11
There has been a number of different efforts in recent time to further enhance the Linux kernel's scheduler to better adapt to modern hardware architectures whether it be for Intel hybrid CPU designs, adapting to new CPU cache configurations, or just better scaling with today's ever-increasing core counts. Another scheduler effort detailed this week is "Nest" that aims to keep tasks on "warm cores" with hopes of lower latency due to being already at higher clock/performance states and ideally operating at an optimal turbo/boost frequency. The Nest developers find that their scheduler "improves performance 10%-2x and can reduce energy usage" with modern hardware...

CUPS 3.0 Continues Being Crafted To Overhaul Linux Printing

Phoronix - Thu, 09/15/2022 - 17:25
Ever since OpenPrinting took over CUPS upstream from Apple, this widely-used, open-source print server has been back to having a vibrant future. CUPS development ceased at Apple and there wasn't much going on until last year when CUPS founder Michael Sweet and OpenPrinting provided new life to the project...

Intel Working On Energy Aware Scheduling For x86 Hybrid CPUs

Phoronix - Thu, 09/15/2022 - 17:00
For a number of years Arm CPUs on the mainline Linux kernel have supported Energy Aware Scheduling (EAS) as a means of providing the kernel's scheduler with the information to influence its scheduling decisions based on the estimated energy consumed by the CPU cores. EAS employs an energy model for helping to place tasks between the big.LITTLE cores for optimal energy efficiency and a minimal impact on throughput. Intel has been working to eventually support Energy Aware Scheduling on their x86 hybrid CPUs too...

Cemu 2.0-2 Released For This Open-Source, Linux-Supported Wii U Emulator

Phoronix - Thu, 09/15/2022 - 16:52
Released last month was Cemu 2.0 as open-source software and with Linux support for this Nintendo Wii U emulator that for years has been in development but up to that point closed-source and Windows-only. Cemu 2.0 continues advancing with another bug-fixing update out today...

One day in March of 2020, a few of my Opensource.com teammates and I grabbed lunch to talk about how we would work from home for the next couple of weeks until this pandemic got nipped in the bud. At the end of the work day, I packed up my laptop and walked out the door of our office building. Several months later, we were all still working from home. None of us had returned to our office-based workstations. In July 2020, using safety precautions, we were granted access to our workstation solely to retrieve personal items. My desk was left exactly as I left it that afternoon in March. Expiring snacks stashed in my secret drawer. Picture frames collecting dust. Comic strips pinned up.

And a pile of several bound copies of Best of a decade on Opensource.com 2010-2019. Our last yearbook that was published (and printed)!

Like most folks, the Opensource.com community had to pivot how we operated in order to stay connected. Sure, we continued our weekly video calls. But in-person conferences, a unique time where people would travel from all over the world to be together, were out of the question. Though some of this operational stuff has changed, the connection with one another has strengthened. It is due time to publish a new yearbook to honor that connection. This yearbook was created to celebrate our correspondents.

The Opensource.com Correspondent Program recognizes the critical group of our most trusted and committed contributors. We recently closed out yet another successful program year with 24 correspondents. Each correspondent selected their favorite article to be included in this downloadable yearbook. In it, you'll find Raspberry Pi tutorials, career stories, home automation tips, Linux tricks, and much more.

The above screenshot is from a recent video call with a few of our correspondents. This community reaches far in locale (North Carolina, Minnesota, California, Germany, India, and New Zealand to name a few) and wide in experience (educators, hobbyists, sysadmins, podcasters, and more).

I'm looking forward to spending another year with the Opensource.com community, whether that is through video calls, in-person events, an Internet DM, or simply reading your article. How would you like to participate?
