Tools, services, error recovery, procedures, docs, organizationDelegation of responsibilities (Project, VO, service, site, …)Crucial role of Grid Operations Center (GOC)

How to support people people relationsFace-face meetings, phone cons, 1-1 interactions, mail lists,

etc. How to test and validate Grid tools and applications

Vital role of testbeds How to scale algorithms, software, process

Some successes, but “interesting” failure modes still occur How to apply distributed cyberinfrastructure

Successful production runs for several applications

Disaster PlanningEmergency Response


Paul Avery 37

Grids and Disaster Planning / Emergency Response

Inspired by recent eventsDec. 2004 tsunami in IndonesiaAug. 2005 Katrina hurricane and subsequent flooding(Quite different time scales!)

Connection of DP/ER to GridsResources to simulate detailed physical & human

consequences of disastersPriority pooling of resources for a societal good In principle, a resilient distributed resource

Ensemble approach well suited to Grid/cluster computing

E.g., given a storm’s parameters & errors, bracket likely outcomes

Huge number of jobs requiredEmbarrassingly parallel


Paul Avery 38

DP/ER Scenarios Simulating physical scenarios

Hurricanes, storm surges, floods, forest firesPollutant dispersal: chemical, oil, biological and nuclear spillsDisease epidemicsEarthquakes, tsunamisNuclear attacksLoss of network nexus points (deliberate or side effect)Astronomical impacts

Simulating human responses to these situationsRoadways, evacuations, availability of resourcesDetailed models (geography, transportation, cities,

institutions)Coupling human response models to specific physical

scenarios Other possibilities

“Evacuation” of important data to safe storage


Paul Avery 39

DP/ER and Grids: Some Implications

DP/ER scenarios are not equally amenable to Grid approach

E.g., tsunami vs hurricane-induced floodingSpecialized Grids can be envisioned for very short response timesBut all can be simulated “offline” by researchersOther “longer term” scenarios

ER is an extreme example of priority computingPriority use of IT resources is common (conferences, etc) Is ER priority computing different in principle?

Other implicationsRequires long-term engagement with DP/ER research communities(Atmospheric, ocean, coastal ocean, social/behavioral, economic)Specific communities with specific applications to executeDigital Divide: resources to solve problems of interest to 3rd WorldForcing function for Grid standards?Legal liabilities?
