Torsten Hoefler's Network Topology Repository!

Description

This page is merely for the entertainment of the viewer. It shows graphs of the physical network structure of some large-scale systems (powered by graphviz). Contact me if you want your system graphed!

Big Red @ Indiana University

  • 1024 nodes quad core PPC 970
  • 160 32-port Myrinet 2G crossbars
  • 3-stage folded Clos topology (full bisection bandwidth)

Odin @ Indiana University

  • 128 nodes quad core Opteron 1GHz nodes
  • 18 24-port InfiniBand SDR crossbars
  • full 2-stage folded Clos network (full bisection bandwidth)

CHemnitzer Linux Cluster (CHiC) @ Technical University of Chemnitz

  • 575 nodes quad core Opteron nodes
  • 112 24-port InfiniBand SDR crossbars
  • nearly a 3-stage folded Clos topology (full bisection bandwidth)

Deimos @ Technical University of Dresden

  • 729 nodes quad core Opteron nodes
  • 108 24-port InfiniBand SDR crossbars
  • "line-Clos" (line of 2-stage folded Clos switches) topology

Atlas @ Lawrence Livermore National Laboratory

  • 1142 nodes quad core Opteron nodes
  • 192 24-port InfiniBand SDR crossbars
  • full 3-stage folded Clos topology (full bisection bandwidth)

Ranger @ Texas Advanced Computing Center

  • 4081 nodes
  • 1365 24-port InfiniBand SDR crossbars
  • folded Clos topology (?) (full bisection bandwidth)

Thunderbird @ Sandia National Lab

  • 4391 nodes
  • 569 24-port InfiniBand SDR crossbars
  • folded Clos topology (half bisection bandwidth)

Tsubame @ Tokio Institute of Technology

  • 1354 nodes
  • 351 24-port InfiniBand crossbars
  • close-to folded Clos topology (half bisection bandwidth)

Jaguar XT-4 partition @ Oak Ridge National Lab

  • 7947 nodes
  • SeaStar 2 21x16x24 3D-Torus network
  • I'm sure you would have guessed that the ball below is a 3d-torus ;)

Jaguar XT-5 partition @ Oak Ridge National Lab

  • 18851 nodes
  • SeaStar 2 25x32x24 3D-Torus network
  • I'm sure you would have guessed that this giant donut is a 3d-torus ;)
