  • Facebook/Meta Tackling Transparent Page Placement For Tiered-Memory Linux Systems - Phoronix

    Back during the Linux 5.15 cycle Intel contributed an improvement for tiered memory systems where less used memory pages could be demoted to slower tiers of memory storage. But once demoted that kernel infrastructure didn't have a means of promoting those demoted pages back to the faster memory tiers should they become hot again, though now Facebook/Meta engineers have been working on such functionality. 

    Prior to the Linux 5.15 kernel, during the memory reclaim process when the system RAM was under memory pressure was to simply toss out cold pages. However, with Linux 5.15 came the ability to shift those cold pages to any slower memory tiers. In particular, modern and forthcoming servers with Optane DC persistent memory or CXL-enabled memory, etc. Therefore the pages are still accessible if needed but not occupying precious system DRAM if they aren't being used and to avoid just flushing them out or swapping to disk. 

  • Linux 5.17 To Boast Latency Optimization For AF_UNIX Sockets - Phoronix

    Net-next has been queuing a number of enticing performance optimizations ahead of the Linux 5.17 merge window kicking off around the start of the new year. Covered already was a big TCP optimization and a big improvement for csum_partial() that is used in the network code for checksum computation. The latest optimization is improving the AF_UNIX code path for those using AF_UNIX sockets for local inter-process communication. 

    A new patch series was queued up on Friday in net-next for improving the AF_UNIX code. That patch series by Kuniyuki Iwashima of Amazon Japan is ultimately about replacing AF_UNIX sockets' single big lock with per-hash locks. The series replaces the AF_UNIX big lock and also as part of the series has a speed-up to the autobind behavior. 

  • Nvidia Pascal GPU, DX12 and VKD3D: Slideshow time! - Boiling Steam

    So Horizon Zero Dawn had a sale recently on Fanatical, and I thought… OK I’ll grab it! It’s time. I first installed it on my workstation that only has a GTX1060 3GB GPU – not a workhorse but a decent card nonetheless for low-to-medium end gaming. I knew very well that Horizon Zero Dawn is a DX12 game and that Pascal architecture (Nvidia 10xx basically) and earlier versions do not play very well with DX12 games running through vkd3d-proton, the DX12 to Vulkan translation layer.

    Still, I could imagine getting somewhere around 30 FPS on low-to-medium settings, and use FSR if necessary to get to better framerates. Nothing prepared me for the performance I was about to experience.

Garuda Linux: An Arch-Based Linux Distro Built for Speed and Beauty

Garuda Linux is not your regular Arch-based distro. It transforms Linux, especially Arch, into a user-friendly operating system for newcomers. Garuda Linux is an Arch-based distribution that makes Linux installation and setup easy while maintaining the stripped-down, high-performance OS model that Arch is known for. Of all the Linux distros that strive to make it easier to install Arch, Garuda is quite possibly the one that comes closest to the spirit and intent of its upstream parent. Garuda is the perfect distribution for those who want absolute, granular control over what is installed on their system but don’t have the time or technical knowledge necessary to successfully navigate the notoriously complex installation procedure of Arch Linux.

Why It Is Better To Program On Linux

You have probably heard a lot of times that it is better to program on Linux, and programmers use it more often than Windows. Of course, operating systems based on Linux kernel are free and open-source. This is a huge advantage compared to Windows, but what are the important benefits of programming? An open-source system does not help if you are a web programmer. However many programmers prefer Linux. In this article, https://jatapp.com/ web developers will explain why to program on Linux.

5 Best Free and Open Source Subtitle Downloaders

A subtitle is a text representation of the dialogue, narration, music, or sound effects in a video file. Subtitles are available in multiple formats. Subtitles can literally make the difference between being immersed in a movie or only watching the screen, trying to keep up with developments. Good subtitling does not distract but actually enhances viewing pleasure, and even native speakers can find subtitles useful, not only where the individual is hearing-impaired. Read more
