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.

Munich Reversal Turnaround, Linus on the Desktop, and Red Hat Time Protocol

Monday we reported that Munich was throwing in the Linux towel, but today we find that may not be exactly the case. In other news, Linus Torvalds today said he still wants the desktop. There are lots of other LinuxCon links and a few gaming posts to highlight. And finally today, Red Hat's Eric Dube explains RHEL 7's new time protocol. Read more

NHS open-source Spine 2 platform to go live next week

Last year, the NHS said open source would be a key feature of the new approach to healthcare IT. It hopes embracing open source will both cut the upfront costs of implementing new IT systems and take advantage of using the best brains from different areas of healthcare to develop collaborative solutions. Meyer said the Spine switchover team has “picked up the gauntlet around open-source software”. The HSCIC and BJSS have collaborated to build the core services of Spine 2, such as electronic prescriptions and care records, “in a series of iterative developments”. Read more

What the Linux Foundation Does for Linux

Jim Zemlin, the executive director of the Linux Foundation, talks about Linux a lot. During his keynote at the LinuxCon USA event here, Zemlin noted that it's often difficult for him to come up with new material for talking about the state of Linux at this point. Every year at LinuxCon, Zemlin delivers his State of Linux address, but this time he took a different approach. Zemlin detailed what he actually does and how the Linux Foundation works to advance the state of Linux. Fundamentally it's all about enabling the open source collaboration model for software development. "We are seeing a shift now where the majority of code in any product or service is going to be open source," Zemlin said. Zemlin added that open source is the new Pareto Principle for software development, where 80 percent of software code is open source. The nature of collaborative development itself has changed in recent years. For years the software collaboration was achieved mostly through standards organizations. Read more

Arch-based Linux distro KaOS 2014.08 is here with KDE 4.14.0

The Linux desktop community has reached a sad state. Ubuntu 14.04 was a disappointing release and Fedora is taking way too long between releases. Hell, OpenSUSE is an overall disaster. It is hard to recommend any Linux-based operating system beyond Mint. Even the popular KDE plasma environment and its associated programs are in a transition phase, moving from 4.x to 5.x. As exciting as KDE 5 may be, it is still not ready for prime-time; it is recommended to stay with 4 for now. Read more
