  1. High Performance Networks Research Program Project Title: Net100 -- Developing Network-Aware Operating Systems PI: G. Huntoon, T. Dunigan, B. Tierney Institutions: PSC, ORNL, LBL Scheduled Accomplishments Project Goals Develop model for network-aware OS -optimize end-to-end net performance -push network expertise into the OS -eliminate the “wizard gap” -use sensors and probes to tune net applications • Extend/deploy Web100 kernels • create NTAF and prototype NAIB • deploy sensors and probes • demonstrate auto-tuned bulk transfer Future Plans Project Elements • Integrate NAOS into grid applications • Integrate Net100 tools into HPSS • Analyze tuned vs non-tuned apps • Analyze TCP extensions/alternatives • Web100 network-aware OS • Network Tool Analysis Framework • Network Analysis Information Base • DOE distributed applications

  2. Optimize end-to-end network and application performance Push the network expertise into the OS Eliminate the “wizard gap” Migrate away from network-aware applications Project Goals Objective: Develop network-aware operating systems

  3. Web100 network-aware OS (NAOS) instrumented and tunable TCP stack Network Tool Analysis Framework (NTAF) launch network tools to measure network extend/develop tools for network analysis Network Analysis Information Base (NAIB) smart repository for network performance data Distributed applications DOE bulk transfer applications (point to point) grid-based applications PI’s: Huntoon/PSC, Dunigan/ORNL, Tierney/LBL Project Elements

  4. Year 1 extend and deploy auto-tuning Web100 kernels create the NTAF instrument tools (iperf, pipechar, GridFTP) with Web100 interface NTAF with NWS deploy net sensors and probes design and prototype NAIB investigate optimizations for single TCP flows demonstrate auto-tunable bulk transfer (ORNL/NERSC) Scheduled Accomplishments

  5. Year 2 integrate NAOS into multi-site distributed applications integrate Net100 tools into HPSS transfer protocols analyze alternatives/extensions to TCP SCTP, rate-based, multipath analyze impact of tuned applications on non-tuned apps Year 3 integrate NAOS into DOE distributed applications auto-tuning grid applications document and standardize NAOS integrate Net100 into other vendors OS Future Research Plans
