Data Grid Test facility
  • Features
    • 1 Gbit/s uplinks to national backbone
    • Non blocking access to other DAS nodes
    • Computing and networking speed same order of magnitude
    • Location of data visualization and computing independent
    • 4 layers of inter-process communication
      • Shared memory
      • Myrilink (2 Gbit/s) in user space
      • 100 Mbit/s and Gbit/s locally switched Ethernet (kernel space)
      • 1 Gbit/s routed Internet connectivity (kernel space)
  • Many unique research degrees of freedom
  • Infrastructure requirements
