Second Blue Gene system rises up the ranks

Filed under

The system, called Blue Gene Watson and located at IBM's Thomas Watson Research Center, performed 91.3 trillion calculations per second, or 91.3 teraflops. That means it's second only to IBM's original Blue Gene/L system, the fastest supercomputer in the world, located at Lawrence Livermore National Laboratory and clocked at 135 teraflops.

IBM's Watson announcement will come two weeks before an expected bevy of such results, when researchers plan to release the latest list of the world's 500 fastest machines. The list is unveiled twice yearly at supercomputing conferences.

The higher speed, measured with an algebraic calculation test called Linpack, puts IBM another notch ahead of Silicon Graphics, whose Columbia system at NASA reached 51.9 teraflops last fall.

Big Blue has a healthy lead in the list and expects to stay on top. The Livermore machine is in line for another doubling in size and, roughly, performance.

IBM sells the Blue Gene systems for about $2 million per rack; each rack has 1,024 processors, and Blue Gene Watson has 20 racks. IBM also rents out access to the machines.

Blue Gene Watson has been used for protein simulations that tie into biology and drug development research.

SUSE Leftovers

  • openSUSE Heroes meeting, day 2
    After a long, but exciting first day, we even managed to get some sleep before we started again and discussed the whole morning about our policies and other stuff that is now updated in the openSUSE wiki. After that, we went out for a nice lunch…
  • Installing Tumbleweed, November 2016
    The Tumbleweed system that I already have installed had desktops KDE, Gnome, XFCE and LXDE. But for recent intstalls (as with Leap 42.2), I have been going with KDE, Gnome, XFCE, LXQt, FVWM and MATE. So it seemed reasonable for the new Tumbleweed install to follow the same path. I also added Enlightenment for experimenting.

  • LibRetro's Vulkan PlayStation PSX Renderer Released
    A few days back I wrote about a Vulkan renderer for a PlayStation emulator being worked on and now the code to that Vulkan renderer is publicly available. For those wanting to relive some PlayStation One games this week or just looking for a new test case for Vulkan drivers, the Vulkan renderer for the LibRetro Beetle/Mednafen PSX emulator is now available, months after the LibRetro folks made a Vulkan renderer for the Nintendo 64 emulator.
  • Etnaviv DRM Updates Submitted For Linux 4.10
    The Etnaviv DRM-Next pull request is not nearly as exciting as MSM getting Adreno 500 series support, a lot of Intel changes, or the numerous AMDGPU changes, but it's not bad either for a community-driven, reverse-engineered DRM driver for the Vivante graphics cores.
  • Mesa 12.0.4 Being Prepped For Ubuntu 16.10/16.04
    Ubuntu is preparing Mesa 12.0.4 for Ubuntu Xenial and Yakkety users. It's not as great as Mesa 13, but at least there are some important fixes back-ported. Mesa 12.0.4 is exciting for dozens of bug fixes, including the work to offer better RadeonSI performance. But with Mesa 12.0.4 you don't have the RADV Vulkan driver, OpenGL 4.5, or the other exciting Mesa 13 work.
