1. A PPARC funded project Tony Linde Programme Manager AstroGrid in the wider world AstroGrid Consortium meeting Cambridge, UK 10-July-2005

2. 2 Tony Linde 10-July-2005AstroGrid in the wider world What wider world? Astronomy Astro software E-Science VObs projects OSS efforts UK/international

3. 3 Tony Linde 10-July-2005AstroGrid in the wider world What AstroGrid? AstroGrid exists on several levels: Software  Infrastructure Astro vs basic  Tools, add-ons, … Operational  Public grid level Hardware Op.sys, Java, Tomcat, … Services: accounts, storage space, …  User level Basic usage support Advanced support: scripting, workflow packaging, …

4. 4 Tony Linde 10-July-2005AstroGrid in the wider world State of play UK uptake Science: see Nic’s talks Deployment: see Kona’s talk External Integration with astro software  Aladin, TopCat, … RVO deployment  New workflows, applications, DSA plugins IVOA influence  Security & VOSpace  Registry  Need to implement/prototype standards Well regarded in e-Science Not much impact in OSS

5. 5 Tony Linde 10-July-2005AstroGrid in the wider world AstroGrid history Started as grid applications project To use Globus as base Switched to WS as base Built minimal base infrastructure  Until Globus stable Added astro services to that base Now? AstroGrid is GRID AstroGrid is almost wholly home-grown

6. 6 Tony Linde 10-July-2005AstroGrid in the wider world Where now? Continue to develop AstroGrid as GRID (-) Much more to do (+) Fully in control Refactor to use external components (-) Loss of control (+) Less work (?) Adopt Globus wholesale (-) Much more work (+) ?

7. 7 Tony Linde 10-July-2005AstroGrid in the wider world New grid features Security Virtual storage Workflow optimisation Job scheduling Build or steal or use? And then there’s the astro bits…

8. 8 Tony Linde 10-July-2005AstroGrid in the wider world Implications Staffing To support/maintain/develop grid infrastructure To continue to incorporate IVOA standards To build new applications And that is just for the software base + User Support Others: Hardware, networking etc. Involvement in IVOA etc.

9. 9 Tony Linde 10-July-2005AstroGrid in the wider world Wider implications Take-up by other VObs projects Take-up by non-astro projects Who pays? Solutions? Advisory groups Full OSS route ??? Need to start work on solution now…
