Presentation Transcript

  1. Linda Winkler Argonne National Laboratory February 9, 2000 ESnet/MREN Regional Science Grid Testbed www.evl.uic.edu/cavern/EMERGE

  2. DOE EMERGE Participants • ANL • ESnet • iCAIR/Northwestern University • NCSA/UIUC • UIC/EVL • University of Chicago • University of Wisconsin

  3. Goals of EMERGE • Achieve optimal end-to-end performance for a set of applications • Achieve better understanding of service deployment and management issues through testbed experience • Build and maintain a persistent testbed infrastructure • Enable dynamic network configuration • Use GARA to perform admission control, manage network resources, and configure edge devices • Use GARA to monitor and schedule testbed activity • Determine traffic conditioning requirements based on real apps • Determine how to measure end-to-end performance • Determine how to validate services: throughput, latency, jitter, loss rate, … • Study interdomain interoperability issues • Evaluate a MPLS label-switched router as a Diffserv router

  4. DOE Science Grid Applications ESnet Abilene EMERGE

  5. DOE EMERGE Testbed

  6. Globus Grid Services Package • Deploy standard infrastructure across sites participating in EMERGE • Provide maximum capabilities to applications • Increase what can be “taken for granted” when developing applications • Reduce deployment burden at sites • Services include • Authentication • Resource discovery • Resource management • Instrumentation

  7. DS Components • EF Cisco model • Ingress (classify, mark, police) CAR • Egress (bandwidth allocation) WFQ • CAR Traffic Conditioner • Meter, mark and police (drop) • Queueing • WFQ • PQ • GARA Bandwidth Broker • Admission control • Resource management • Router configuration • Shaping (GTS, DTS)

  8. Timeline • Establish connectivity (Dec - Jan) • Mostly complete • Setup accounts for Emerge-User (January!) • Measure baseline connectivity (end-to-end 100Mbps) • Install and customize GARA (Jan - Feb) • In progress • Configure and validate with GUI using basic tools • Perform basic experiments (Feb - Mar) • Test applications on the Testbed (Mar - ?) • Start with multi-domain issues (Apr - May)

  9. Testing • Each EMERGE site provides a test machine (Linux RH6.1) • Phase 1- measure baseline end-to-end BE performance (desire 100 Mbps ~ achieving 70-80 Mbps) • Phase 2- measure single stream end-to-end Premium service • Phase 3- measure application end-to-end performance • Phase 4- measure multiple stream end-to-end Premium service
