  • This shows the National Centre, 8 regional centres and 2 laboratories in blue That is the original set up at the start of UK e-Science August 2001 NeSC is jointly run by Edinburgh & Glasgow Universities In 2003 several smaller centres were added (vermilion) (1 st call out) The e-Science Institute is run by the National e-Science Centre. It runs a programme of events and hosts visiting international researchers. It was established in 2001. The Open Middleware Infrastructure Institute was established in 2004, to provide support and direction for Grid middleware developed in the UK. It is based at the University of Southampton. The Grid Operations Centre will be established in 2004. (2 nd call out) The Digital Curation Centre was established in 2004 by the Universities of Edinburgh and Glasgow, the UK Online Library Network at the University of Bath, and the Central Laboratories at Daresbury and Rutherford. It’s job is to provide advice on curating scientific data and on preserving digital media, formats, and access software. (3 rd call out) Edinburgh is one of the 4 founders of the Globus Alliance (Sept 2003) which will take responsibility for the future of the Globus Toolkit. The other founders are: Chicago University (Argonne National Lab), University of Southern California, Los Angeles (Information Sciences Institute) and the PDC, Stockholm, Sweden (4 th call out) The EU EGEE project (Enabling Grids for E-Science in Europe) is establishing a common framework for Grids in Europe. The UK e-Science programme has several connections with EGEE. NeSC leads the training component for the whole of Europe.

Sinnott Paper Presentation Transcript

  • 1. The e-Context of ENROLLER Prof Richard O. Sinnott Technical Director National e-Science Centre [email_address] 16 th April 2010
  • 2. e-Science and e-Research
    • Goal: to enable better research in all disciplines
    • Method: Develop collaboration supported by advanced distributed computation
      • to generate, curate and analyse rich data resources
        • From experiments, observations and simulations
        • Quality management, preservation and reliable evidence
      • to develop and explore models and simulations
        • Computation and data at all scales
        • Trustworthy, economic, timely and relevant results
      • to enable dynamic distributed collaboration
        • Facilitating collaboration with information and resource sharing
        • Security, trust, reliability, accountability, manageability and agility
    The challenge is to develop an integrated approach to all three Often realised through Grids and Grid infrastructures
  • 3. The Grid Context
    • There are many Grids
      • Data Grids, Compute Grids, Information Grids, Enterprise Grids, …
    • There are many ways to build Grids
      • Grid middleware (many flavours),
      • Web services,
      • Clouds,
      • Web2.0,
      • internet computing, …
    • There are many moving targets
      • changing middleware, changing standards, changing sciences, changing resources, new questions, new funding streams…
    • There has been a lot of hype
    • There has been a lot of money invested
    • There are lots of projects and big scientific challenges
    • There is an urgent need to build user communities
    • There needs to have much more research pull than middleware push
      • … there are many more things that could go here!
  • 4. UK e-Science Core Programme
    • Major cross council initiative
      • AHRC, BBSRC, EPSRC, ESRC, MRC, NERC, PPARC/STFC, …

    • Security
      • Key is that should support
        • seamless access to a heterogeneous variety of “ distributed ” compute and data (and other) resources
          • Often domain specific – especially data!
        • single sign-on
          • Authenticate once and access numerous distributed resources
      • A A A A ( +privacy, confidentiality, integrity… )
          • Authentication
            • (know who “they” are)
          • Authorisation
            • (decide what “they” can do and enforce it)
          • Auditing/accounting
            • (keeping track of who did what/when for security checks/charging etc)
  • 17. Ease of Use
    • For Grids/e-Research to be truly successful
      • have to be made as seamless to access and use as the internet
        • Forget training, education for some (most?) users!
      • have to be based on research pull and not middleware push
      • experiences in various projects and across whole e-Science programme have shown that users don’t like digital certificates
  • 18. User Oriented Security
    • A _ _ _
      • Federated Authentication, e.g. through Shibboleth
    Service provider 5. User accesses resource Web site/e-Journal Identity Provider Home Institution W.A.Y.F. Federation User AuthN Log-in once and roam
    • User points browser at Grid resource/portal (or non-Grid resource)
    2. Shibboleth redirects user to W.A.Y.F . service 3. User selects their home institution 4. Home site authenticates user LDAP
  • 19. _ A _ _
    • Authorisation
      • Defining what they can do and define and enforce rules
        • Each site will have different rules/regulations
      • Also known as Virtual Organisations (VO)
        • Collection of distributed resources shared by collection of users from one or more organizations typically to work on common research goal
          • Provides conceptual framework for rules and regulations for resources to be offered/shared between VO institutions/members
          • Different domains place greater/lesser emphasis on expression and enforcement of rules and regulations (policies)
