Extreme Scaling GoalsExtreme Scaling Goals• To create a robust 10,000 node autonomous ad hoc sensor
network in an operationally relevant environment for demonstrating the capabilities in the monitoring and protection of long linear structures, by the end of FY ’04
• NEST Extreme Scaling Analysis– Robust 10,000 node autonomous ad hoc sensor network– Operationally relevant environment– Demonstrating the capabilities– Monitoring and Protection – Long linear structures (Pipelines, borders, …)– End of FY ’04
Extreme Scaling ResponsibilitiesExtreme Scaling Responsibilities
• Ohio State is the lead
• Berkeley’s role– Reprogramming a 10,000 node network
• Software modules• Network reprogramming boot loader
