GEODE Workshop 16 th January 2007 Issues in e-Science Richard Sinnott University of Glasgow Ken Turner University of Stirling

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 e-Science and the Grid Grids are the infrastructure for e-Science: metaphor of Power Grid computation and data resources on demand ‘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’ John Taylor Director General of Research Councils Office of Science and Technology

GEODE Workshop 16 th January 2007 The e-Science Approach sensor networks shared data archives computers software colleagues/collaborators instruments Grid transforming science, engineering, medicine and business: driven by exponential growth in data and computing enabling a whole-system approach

GEODE Workshop 16 th January 2007 Grid Techniques application areas: e-social science e-health life sciences physics... toolsets: Globus Toolkit OMII (Open Middleware Infrastructure Institute) gLite (Grid lightweight middleware)...

GEODE Workshop 16 th January 2007 CeSC (Cambridge) Digital Curation Centre e-Science Institute OMII-UK e-Science in the UK Grid Operations Support Centre National Centre for e-Social Science National Inst. Environmental e-Science NERC e-Science Centre OMII-UK NeSC (leader/ coordinator) Core NGS Nodes + HPCx + CSAR Scottish Grid Service NeSC-3 to Aug 2008

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 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

GEODE Workshop 16 th January 2007 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...

GEODE Workshop 16 th January 2007 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
