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.

Thunderbolt 3 in Fedora 28

  • The state of Thunderbolt 3 in Fedora 28
    Fedora 28 is around the corner and I wanted to highlight what we did to make the Thunderbolt 3 experience as smooth as possible. Although this post focuses on Fedora 28 for what is currently packaged and shipping, all changes are of course available upstream and should hit other distributions in the future.
  • Thunderbolt 3 Support Is In Great Shape For Fedora 28
    Red Hat developers have managed to deliver on their goals around improving Thunderbolt support on the Linux desktop with the upcoming Fedora 28 distribution update. This has been part of their goal of having secure Thunderbolt support where users can authorize devices and/or restrict access to certain capabilities on a per-device basis, which is part of Red Hat's Bolt project and currently has UI elements for the GNOME desktop.

New Terminal App in Chome OS Hints at Upcoming Support for Linux Applications

According to a Reddit thread, a Chromebook user recently spotted a new Terminal app added to the app drawer when running on the latest Chrome OS Dev channel. Clicking the icon would apparently prompt the user to install the Terminal app, which requires about 200 MB of disk space. The installation prompt notes the fact that the Terminal app can be used to develop on your Chromebook. It also suggests that users will be able to run native apps and command-line tools seamlessly and securely. Considering the fact that Chrome OS is powered by the Linux kernel, this can only mean one thing. Read more
