TJG -- 21st NORDUnet conference --Iceland - 24/AUG/2003 2

Outline

1. A vision of information/knowledge progress

2. The state of NSF CISE vision of CI

3. Some thoughts on a strategy


This big Vision is :Cyberinfrastructure

An old idea of information processing using machines made from :

• INPUT/OUTPUT devices• PROCESSORS

• MEMORY• CONNECTIONS

Becomes a new idea through:• Very BIG Sizes and • GLOBAL distances

Setting the Stage


Cyberinfrastructure Promise

• Ubiquitous, digital knowledge environments that are both interactive and functionally complete…………

• revolutionize the processes of discovery, learning and innovation across the science and engineering frontier.


Characteristics of Cyberinfrastructure

• Community-Driven• Distributed Collaboration• Virtual Organization• Multidisciplinary in scale and scope• International in scale and scope• Interoperable• Supporting Data- and Compute-Intensive Applications• High end to desktop• Distributed• Heterogenuous• Complex• Reusable


Cyberinfrastructure Early Adopters

• Network for Earthquake Engineering Simulation (NEES)

• National Ecological Observatory Network (NEON)

• Biomedical Informatics Research Network (BIRN)

• Extensible Terascale Facility (ETF)


CalTech Argonne

Terascale Extensions Program

Hubs

New Partners


FY2003 ETF Enhancements

• Solicitation to attract new resource partners (due June 9th)

• Funding connection and integration• Resources may include:

– Archival repositories– Digital libraries– Computational resources– Sensor networks

Challenging Context

• Institutional & Infrastructural Ecology– Technological change more rapid than institutional change

• Broadening Participation• Community-Building – Role of early adopting

communities as drivers/partners ?• Seamless Integration of New and Old

– Balancing upgrades of existing and creation of new resources– Legacy data/models

• Providing sustainable support


Plan of Action

• Focused, cross-cutting attention on cyberinfrastructure – not business as usual

• Internal NSF planning now underway - active discussion on specific cyberinfrastructure issues

• Community building - broad consultations with scientific communities will intensify in coming months

• Summer 2003 workshops and town hall meetings – management models

• NSF FY05 budget planning for cyberinfrastructure beginning shortly


Outline



3. Some thoughts on a strategy… (a modest proposal ?)


Why collaborate ?

• (1) Altruism

• (2) Self- Interest – For this project choose (2) because busy

communities often respond easily to Self-interest (especially with visible Leveraged outcomes for the community agenda)


A CS Strategy for CI building ?

• PICK some existing global big science projects

• Engage them in a revolution using projects building/using cyberinfrastructure components

• Agree to Find “de facto standards” for mutual benefit across cultural divides


Leverage at the Interface(Equal Partnership Collaborations)

• SCIENCE APPLICATIONS

• COMPUTER TOOLS


A Science Strategy for CI building ?

• PICK some existing computer science projects

• Engage them in a revolution using projects building/using cyberinfrastructure components

• Agree to Find “de facto standards” for mutual benefit across cultural divides


CI Is a Large SYSTEM so build it as most very large systems are

built-- – Bottom up --- micro– Top down --- macro– Middle out – engineering choices for standard

interfaces (Standards solutions etc.)

• --• USE Cyber infrastructure rapid proto demos• And keep them alive after the demo …


Cyberinfrastructure vision involves a Large COMPLEX system – (with Synergy?)

• top down

• bottom up

• or middle out


Bad News

• Crossing cultures to enable collaborations is not a well understood process.

• New tools for this are needed in computers and communications.

• Agreements to enabling standards requires people compromising to agree to further the big agenda – “big thinkers”.


Good News - a Win-win Situation Exists

• Essential changes in information access are happening now, (not just a little faster, bigger but - much faster, bigger, wider!).

• Solving very hard problems faster and better by the collaborations “idea” by some frontiersmen is already agreed to .

• Committed problem solvers will “climb mountains “ to solve their problem agenda and will even work with people outside their culture – sometimes.


Some Principles for a Global Cyber Infrastructure and for E-science Rapid Prototyping

Some proposed principles under current discussion 0] The cost and complexity of 21st Century Science requires the creation

of advanced and coherent global Infostructure (information infrastructure).

1] The construction of a coherent Global Infostructure for Science

requires definition and drivers from Global Applications (that will also communicate with each other)

2] Further, forefront Information Technology must be incorporated into

this Global lnfostructure for the Applications to reach their full potential for changing the way science is done


Some CI Building Tactics

• Use common agendas, not common check books.( i.e. Keep money with owning agencies as much as possible.)

• Full credit to all

• Give Endorsements across cultures whenever useful.
