Speeding Up The Linux Kernel With Transparent Hugepage Support

Filed under
Linux

Last month we reported on the 200 line Linux kernel patch that does wonders for improving the desktop responsiveness of the system. There was certainly much interest (over 100,000 views to both of our YouTube videos demonstrating the change) but this patch really didn't speed up the system per se but rather improved the desktop interactivity and reduced latency by creating task-groups per TTY so that the processes had more equal access to the CPU. There is though an entirely different patch-set now beginning to generate interest among early adopters that does improve the kernel performance itself in compute and memory intensive applications and it's the Transparent Hugepage Support patch-set. Here are our initial tests of the latest kernel patches that will hopefully be finding their way into the mainline Linux kernel soon.

As was pointed out in our forums, the Transparent Hugepage Support patch-set has been updated against the Linux 2.6.37 kernel code-base and is showing to improve the performance in compute/memory intensive applications by a couple percent at this time. The Transparent Hugepage Support in the Linux kernel works by reducing the number of TLB (Translation Lookaside Buffer) entries that such applications need and at the same time increasing the cap that a TLB cache can provide.

Leftovers: OSS and Sharing

Microsoft Begs, Bugs, and Bug Doors

  • Don't install our buggy Windows 10 Creators Update, begs Microsoft
    Microsoft has urged non-tech-savvy people – or anyone who just wants a stable computer – to not download and install this year's biggest revision to Windows by hand. And that's because it may well bork your machine. It's been two weeks since Microsoft made its Creators Update available, and we were previously warned it will be a trickle-out rather than a massive rollout. Now, Redmond has urged users to stop manually fetching and installing the code, and instead wait for it to be automatically offered to your computer when it's ready.
  • Microsoft Word flaw took so long to fix that hackers used it to send fraud software to millions of computers
    A flaw in Microsoft Word took the tech giant so long to fix that hackers were able to use it to send fraud software to millions of computers, it has been revealed. The security flaw, officially known as CVE-2017-0199, could allow a hacker to seize control of a personal computer with little trace, and was fixed on April 11 in Microsoft's regular monthly security update - nine months after it was discovered.

FOSS Licensing (and Lack Thereof)

    All of the code, information and tools are made available for reuse.
  • JRC: ‘Releasing code without a licence hinders reuse’
    Projects that publish source code without a licence weaken the reusability of their code, warns Stefano Gentile, a copyright and trademark specialist working for the European Commission’s Joint Research Centre (JRC). Currently just 20 % of all projects published on GitHub, one of the most popular source code sharing platforms, have selected a licence for their work - down from about 60% in 2008, Gentile said, quoting numbers published in 2015 by GitHub.

    The Additional Grant of Patent Rights is a patent license grant that includes certain termination criteria. These termination criteria are not entirely unprecedented when you look at the history of patent license provisions in OSI-approved licenses, but they are certainly broader than the termination criteria [or the equivalent] in several familiar modern licenses (the Apache License 2.0, EPL, MPL 2.0, and GPLv3).
