  • 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

    • Heavy switches/routers for 1 Gbit/s uplink capability
