  1. RENCI: ExoGENI and Shakedown ExperimentsIlyaBaldin, Paul Ruth, AnirbanMandal, YufengXin, Shu Huang, Claris Castillo, Chris Heerman, Brian Blanton, Jeffery Tilson (RENCI)Jeff Chase, Victor Orlikowski (Duke)Hakim Weatherspoon(Cornell) GENI Science Shakedown ExoGENI: Recently added Features Discussion SoNIC: Software-defined Network Interface Card Infrastructure Updates Application Status • Multipoint Topologies: Virtual layer-2 networks spanning 3 or more racks. • Initial geni-get support in images • Speaks-for credential support • Federation API/GENI portal supportin Flukes • iSCSI Storage support • ADCIRC (Storm surge model) • Running on ExoGENI • Image imported into InstaGENIhas filesystem size limitation • MotifNetwork (Computational Genomics) • Partially Running on ExoGENI • Weak performance isolation between VMs in ExoGENI • Difficulty importing custom images into InstaGENI • Filesystem size limitations in InstaGENI • Enables novel network research • Available bandwidth estimation • Covert timing channels • Network profiling/modeling • Network tomography Initial Results • ADCIRC Scaling (4-16 cores/VM) • Observation 1: ADCIRC performance is more sensitive to latency than bandwidth • Observation 2: Having NFS server remotely incurs a 26% performance penalty for 16 processor run • Enables unique capabilities • Implement PHY in software • Software access to PHY in realtime @ 10Gbps • Precise packet timestamping by counting idle IPG Packet i Packet i+1 Packet Generation Packet Capture SoNIC-enabled ExoGENI SoNIC@UC Davis SoNIC@RENCI Available bw estimation Network Profiling Traffic Measurements Covert channel • New Racks: • UC Davis (Davis, CA) • Starlight (Chicago, IL) • OSF/DOE (Oakland, CA) • WVNET (Morgantown, WV) • Network Highlights: • 40Gbps between UVA, Starlight, and OSF • UMass Stitchport • Performance interference • (simultaneous runs) • Execution time doubles with simultaneous ADCIRC runs • Performance isolation is extremely important for ADCIRC The 19th GENI Engineering Conference March 17-19, 2014 Georgia Institute of Technology, Atlanta, GA
