Nearly every supercomputer runs Linux

Just as with the previous list of the Top500 Supercomputers, the Oak Ridge National Laboratory's Cray XT5 'Jaguar' leads the pack with a sustained performance of 1.76 PFlop/s. However, a new Chinese entrant called Nebulae has achieved a higher peak performance of 2.98 PFlop/s (compared to Jaguar's peak of 2.33 PFlop/s) and is placed second overall.

Of the 187 new entrants, all but one are running some variant of Linux and in fact 470 of the Top 500 run Linux, 25 some other Unix (mostly AIX) and the remaining 5 run Windows HPC 2008.

The Chinese systems Nebulae and 7th placed Tianhe-1 are both based on a hybrid design with each node comprising a pair of Intel Xeon processors attached to a pair of GPUs (NVidia for Nebulae and AMD for Tianhe-1) as accelerators. These two systems helped China to take second place for total PFlop/s (9.2%), still trailing USA with 55.4%.

Australia has just one entry in the list

GNOME News: Black Lab Drops GNOME and Further GNOME Experiments in Meson

  • Ubuntu-Based Black Lab Enterprise Linux 11.0.1 Drops GNOME 3 for MATE Desktop
    Coming about two weeks after the release of Black Lab Enterprise Linux 11, which is based on the Ubuntu 16.04.2 LTS (Xenial Xerus) operating system using the HWE (hardware enablement) kernel from Ubuntu 16.10 (Yakkety Yak), Black Lab Enterprise Linux 11.0.1 appears to be an unexpected maintenance update addressing a few important issues reported by users lately.
  • 3.26 Developments
    My approach to development can often differ from my peers. I prefer to spend the early phase of a cycle doing lots of prototypes of various features we plan to implement. That allows me to have the confidence necessary to know early in the cycle what I can finish and where to ask for help.
  • Further experiments in Meson
    Meson is definitely getting more traction in GNOME (and other projects), with many components adding support for it in parallel to autotools, or outright switching to it. There are still bugs, here and there, and we definitely need to improve build environments — like Continuous — to support Meson out of the box, but all in all I’m really happy about not having to deal with autotools any more, as well as being able to build the G* stack much more quickly when doing continuous integration.

Debian and Derivatives

  • Reproducible Builds: week 108 in Stretch cycle
  • Debuerreotype
    The project is named “Debuerreotype” as an homage to the photography roots of the word “snapshot” and the daguerreotype process which was an early method of taking photographs. The essential goal is to create “photographs” of a minimal Debian rootfs, so the name seemed appropriate (even if it’s a bit on the “mouthful” side).
  • The end of Parsix GNU/Linux
    The Debian-based Parsix distribution has announced that it will be shutting down six months after the Debian "Stretch" release.
  • Privacy-focused Debian 9 'Stretch' Linux-based operating system Tails 3.0 reaches RC status
    If you want to keep the government and other people out of your business when surfing the web, Tails is an excellent choice. The Linux-based operating system exists solely for privacy purposes. It is designed to run from read-only media such as a DVD, so that there are limited possibilities of leaving a trail. Of course, even though it isn't ideal, you can run it from a USB flash drive too, as optical drives have largely fallen out of favor with consumers. Today, Tails achieves an important milestone. Version 3.0 reaches RC status -- meaning the first release candidate (RC1). In other words, it may soon be ready for a stable release -- if testing confirms as much. If you want to test it and provide feedback, you can download the ISO now.
