  1. Richard SinnottUniversity of GlasgowKen TurnerUniversity of Stirling Issues in e-Science

  2. Overview • background to e-Science and Grids in UK: • history • applications and toolsets • e-science in the UK • issues and challenges: • simplifying access for end users • the future: • grids tomorrow • Scottish grid service

  3. e-Science and the Grid ‘e-Science is about global collaboration in key areas of science, and the next generation of infrastructure that will enable it’ ‘e-Science will change the dynamic of the way science is undertaken’ JohnTaylor Director General of Research Councils Office of Science and Technology • Grids are the infrastructure for e-Science: • metaphor of Power Grid • computation and data resources on demand

  4. computers software Grid sensor networks instruments shared data archives colleagues/collaborators The e-Science Approach • transforming science, engineering, medicine and business: • driven by exponential growth in data and computing • enabling a whole-system approach

  5. Grid Techniques • application areas: • e-social science • e-health • life sciences • physics ... • toolsets: • Globus Toolkit • OMII (Open Middleware Infrastructure Institute) • gLite (Grid lightweight middleware) ...

  7. Issues and Challenges • not yet a push-button technology • overall architecture for Grids still being defined (Open Grid Services Architecture): • has moved towards web services architecture • architecture not prescriptive: • no hard notion of conformance, compliance or test suites • different solutions need proven to interwork

  8. The Grid Today • mostly users funded to use Grids: • ‘me-Science’ culture • good IT knowledge needed to use Grid middleware • focused more on technology than on supporting research • mostly oriented towards system developers • lack of real services and data sets • need to move towards service provision

  9. Ease of Use • for e-science to be truly successful: • must be as seamless and easy to use as the Internet • must be based on research pull and not middleware push • digital certificates for authentication are disliked • must be easy to get onto the Grid

  10. Current Security Approach • Public Key Infrastructure (X.509) is common: • Step 1. • get a certificate • Step 2. • register with places you expect to use • Step 3. • read the manuals for how to submit and run jobs

  11. How Can we Improve Things? • domains should follow a common approach • best to exploit local authentication: • sites know if users still at institution • sites know what user privileges should be • approach supported by Shibboleth: • based on trust between domains • home sites authenticate users • authorisation is role-based • will replace Athens across the UK

  12. Grids Tomorrow • resources accessed much as for the Internet: • log in once at home site • roam wherever credentials permit • application sets for different communities: • research applications wrapped as Grid services • sites defines who can use what and when • data sets hosted on/accessible through Grid: • occupational data sets • census databases ...

  13. Scottish Grid Service • case is currently being formulated: • outline proposal agreed by SFC as ‘strategically important for Scotland’ • move towards service-based infrastructure • application areas: • physics, life sciences • bioinformatics, electronics • arts and humanities, social science ... • may need to pick the most suitable disciplines

  14. Find out More • NeSC are happy to provide training: • lectures, seminars • themed events, workshops • NeSC web site (www.nesc.ac.uk): • primary source for UK e-Science • who is doing what on what projects • newsletter
