  1. Virtual Collaboration Centerwww.vcc.cnidr.org Daniel Stevenson, MCNC stevenso@anr.mcnc.org Dorcas Stapleton, MCNC dorcas@cnidr.org

  2. Overview • Information Technology focus • Novel optical networking techniques • Applications to Grid Computing • Target • bottlenecks in networked applications • Dearth of network expertise in applications researchers

  3. Scope • Development of Proof of Concept • Novel Optical LAN and Adapters • Grid computing applications • Information retrieval tools • Porting grid tools to PoC LAN • Testbed • Leveraging network expertise

  4. Leveraging Network Expertise • Potential collaborative applications • Bridge barriers using network expertise • Emphasis on regional academic inst. • Local R1’s and HBCU’s • Identified several opportunities, but.. • Long lead times & resource limitations • Limited impact

  5. Novel (radical) Approach • Rethinking the network fundamentals • 20 year technology lifetime • Rapid changes in optical technology • No legacy mindsets • Protocol simplification • Elimination of round trip handshakes • Optimized implementation • Functional placement: optics, electronics & software • Low latency & high performance • No data buffering in network • Intelligence concentrated at network edge

  6. Network Technology • Optical Burst Switching • Switched light path dWDM network • no electro-optical conversion or buffering • Just in Time control protocol • Tell and go network control protocol • Data transparent to intermediate network • no assumptions made on signal format or rate • Analog and various digital signals

  7. JIT Comparison to TCP • No buffering • More optimistic • Less latency • connection est. • error recovery • No slow start • Less time to deliver data once started

  8. Research Relationships • VCC: NASA Ames (NAS) • OBS Network Adapter & LAN • Applications over JIT / OBS • Jumpstart: DoD (ITIC & ARDA) • Just in Time definition, implementation, evaluation in ATDnet (NSA-LTS to NRL) • OBS network modeling and analysis • Future: routing & net management • Under exploration: DoE (transport layer)

  9. Grid Computing Applications • GridIR • proposed information retrieval service • secure database indexing, searching, retrieval, and discovery on the Grid • Working closely with Global Grid Forum • Grid tools over JIT – OBS • Exploring, designing, porting • Evaluating, benchmarking, improving

  10. VCC Grid Testbed • Expansion in progress (Beta) • 2 clusters + 1 Stand Alone Master • 7 slave + 1 master node per cluster • Fast Ethernet connected • Each node has • 2x 1.56 GHz AMD Athlon 1800+ MP • 1 GB DRAM slave, 2 GB DRAM master • 40 GB HD slave, 2x 40 GB HD master • 900 GB RAID Direct Attached Storage • 30 GB x 7 DLT stacker • Additional expansion planned for Y2
