Introduction

• Standards for Interoperable Grids Experience
  from NextGRID and OMII-Europe
• Clive Davenhall
• National e-Science Centre, University of Edinburgh

2
Introduction

• Welcome.
• Administrative arrangements.
• Purpose of the meeting
• Overview of the Grids standards landscape.
• Not a detailed treatment of any particular
  standard.
• Introductions.

3
OMII-Europe

• Promoting interoperable Grid systems.
• Identifying software components that will
  interoperate across heterogeneous Grid middleware
  stacks.
• Endorses particular standards which are important
  for interoperability.
• Emphasis on re-engineering to support
  interoperability rather than reinvention.
• Developing a repository of quality-assured
  components that support interoperability.

4
OMII-Europe

• Sixteen partner institutions.
• Three in the UK.
• The remainder are in Europe, the US and China.
• Funded by the EU (at least the European part).
• Started in May 2006.

5
NextGRID

• Developing an architecture for next generation
  Grids.
• Enable or support widespread use.
• Business and commerce, not just academia.
• Address security, legal and privacy issues.
• Support economically viable business models.
• Consolidate and standardise the solutions adopted
  to these problems.

6
NextGRID

• Mixture of industrial and academic institutions.
• Twenty two partners.
• Seven in the UK.
• Coordinated by EPCC and NeSC.
• Funded by the EU.
• Started in September 2004.
• Ends on 31 March 2008.

7
NextGRID Architecture

• NextGRID has developed an architecture capable of
  supporting the anticipated modes of use.
• Details are not germane today.
• Worth briefly mentioning the principles behind
  it.
• Discussed in the NextGRID White Paper.
