SGI Expanding the Reach of Linux

Filed under
Interviews

Steve Neuner, the director for Linux engineering at SGI, has been pushing Linux up the scalability ladder for the better part of the 21st century. In August of this year, SGI announced that they were able to run a single system image of the Linux OS over 1024 processors on an Itanium-based Altix 4700 supercomputer. How was this feat accomplished? This week at the Gelato Itanium Conference and Expo (ICE) in Singapore, Neuner presented a session that described the Linux kernel modification that helped to make this possible. HPCwire caught up with him before the conference to ask him about the Linux improvements and where the future of single system image scalability is headed.

HPCwire: Can you give us a brief time line of how Linux has scaled from 8 processors to 1024 processors over the last five years?

Neuner: In the summer of 2001, we built an early 32 processor prototype system in the lab. SGI used it extensively to begin identifying and fixing scaling issues. This development system was later increased to 64 processors, which became our initial configuration limit for a single system image of the Linux kernel when we launched SGI Altix in February of 2003. A year later, that limit was increased to 256 processors.

Later in February of 2005, we started shipping the 2.6 Linux kernel, which was a major step forward that enabled support for 512 processor systems. In August of this year, this limit was increased to our now current limit of 1024 processors.

  • Chrome OS Gets Material Design for "Do Not Disturb," Android-Like Screenshots
    Chromium evangelist François Beaufort is sharing today information on a new Material Design refresh for Google's Chrome OS' "Do Not Disturb" mode, which landed in the latest Chrome Canary channel. According to the developer, the Material Design refresh for the "Do Not Disturb" mode will make the Notification Center look nicer, but also consistent with the Android user experience. Those using the Chrome Canary experimental channel can give it a try right now.
  • System76 'Lemur' and 'Galago Pro' Ubuntu Linux laptops get 8th gen Intel Core CPUs
    The famed Linux-laptop seller also says, "The Lemur you know and love is now even better with the Intel 8th Gen Coffee Lake CPU with 4 cores and 8 threads, allowing you to multitask up to 40-percent faster. The slim, 3.6 lb laptop with impressive 14.1-inch 1080p IPS display is still your perfect travel companion; easy to carry from meeting to meeting or across campus." New processors aside, these laptops should be pretty much identical to prior generations -- which is a very good thing. If you want to configure a Lemur with a Coffee Lake chip, you can build your own here. A Galago Pro with an 8th Gen Intel Core processor can be configured here.

Licences: Eclipse Public Licence 2.0, GPL Copyright Troll, Fiduciary License Agreement 2.0

  • Eclipse Public License version 2.0 added to license list
    We recently updated our list of various licenses and comments about them to include the Eclipse Public License version 2.0 (EPL). In terms of GPL compatibility, the Eclipse Public License version 2.0 is essentially equivalent to version 1.0. The only change is that it explicitly offers the option of designating the GNU GPL version 2 or later as a "secondary license" for a certain piece of code.
  • Linux kernel community tries to castrate GPL copyright troll
    Linux kernel maintainer Greg Kroah-Hartman and several other senior Linux figures have published a “Linux Kernel Community Enforcement Statement” to be included in future Linux documentation, in order to ensure contributions to the kernel don't fall foul of copyright claims that have already seen a single developer win "at least a few million Euros.” In a post released on Monday, October 16th, Kroah-Hartman explained the Statement's needed because not everyone who contributes to the kernel understands the obligations the GNU Public Licence 2.0 (GPL 2.0), and the licence has “ambiguities … that no one in our community has ever considered part of compliance.”
  • Fiduciary License Agreement 2.0
    After many years of working on it, it is with immense pleasure to see the FLA-2.0 – the full rewrite of the Fiduciary License Agreement – officially launch.
