What is AstroGrid?

IVOAUK Effort: Prototype VO infrastructure for IVOA Produce working ‘grid’ UK datacenters

ROE, Cambridge, JBO, MSSL, Leicester

PPARC/IVOA FundedApprox 20 programmers + scientists ROE: Clive, John, Me, Peter. (+Bob, Andy) (+Mike, Nigel, etc)

Finish by end 2004

What are we doing?

Design Astronomical Grid InfrastructureBuild a UK Astronomical Grid What’s a Grid?

Components: Datacenter Registry MySpace Application Server ‘Portal’ User Interface Workflow – designer & executer

Example: Brown Dwarfs

Workflow

Create:Flows, Sequences, BranchesSave, Edit, Test

Execute:Press buttonGo and drink coffee……go on holiday…

Using AstroGrid

Code-your-own:Web Service client toolkits

Perl, Python, Java, etc – and FORTRAN!AstroGrid delegates (Java)

Portal GUIs

Combinations

Publishing Data

Single download & install

Connect to data……depends on data!

IVOA compatible……when it happens

Execute:Go on holiday

Challenges

Agreeing standards…

Completing ‘critical mass’

User acceptanceMake sure it worksMake sure it’s easyProvide more science

Summary

UK effort: Influencing IVOA IVOA standards compatible

Data publishing easierGreatly extends data available to astronomersNot quite a pipe dream: Data sets being published now
