Gridpp vision

From Web to Grid - Building the next IT Revolution


The next IT revolution will be the Grid. The Grid is a practical solution to the data-intensive problems that must be overcome if the computing needs of many scientific communities and industry are to be fulfilled over the next decade.


The GridPP Collaboration aims to develop and deploy the largest-scale science Grid in the UK for use by the worldwide particle physics community.

GridPP Vision

Many Challenges..

Shared distributed


For all experiments

Tony Doyle - University of Glasgow

Gridpp objectives

1. SCALE: GridPP will deliver the Grid software (middleware) and hardware infrastructure to enable the testing of a prototype of the Grid for the LHC of significant scale.

2. INTEGRATION: The GridPP project is designed to integrate with the existing Particle Physics programme within the UK, thus enabling early deployment and full testing of Grid technology and efficient use of limited resources.

3. DISSEMINATION: The project will disseminate the GridPP deliverables in the multi-disciplinary e-science environment and will seek to build collaborations with emerging non-PPARC Grid activities both nationally and internationally.

4. UK PHYSICS ANALYSES (LHC): The main aim is to provide a computing environment for the UK Particle Physics Community capable of meeting the challenges posed by the unprecedented data requirements of the LHC experiments.

5. UK PHYSICS ANALYSES (OTHER): The process of creating and testing the computing environment for the LHC will naturally provide for the needs of the current generation of highly data intensive Particle Physics experiments: these will provide a live test environment for GridPP research and development.

6. DATAGRID: Grid technology is the framework used to develop this capability: key components will be developed as part of the EU DataGrid project and elsewhere.

7. LCG: The collaboration builds on the strong computing traditions of the UK at CERN. The CERN working groups will make a major contribution to the LCG research and development programme.

8. INTEROPERABILITY: The proposal is also integrated with developments from elsewhere in order to ensure the development of a common set of principles, protocols and standards that can support a wide range of applications.

9. INFRASTRUCTURE: Provision is made for facilities at CERN (Tier-0), RAL (Tier-1) and use of up to four Regional Centres (Tier-2).

10. OTHER FUNDING: These centres will provide a focus for dissemination to the academic and commercial sector and are expected to attract funds from elsewhere such that the full programme can be realised.

Grid what s been happening


Grid - What’s been happening?


A unified approach

  • A lot…

  • GGF4, OGSA and support of IBM (and others)

    • [as opposed to .NET development framework and passports to access services]

    • Timescale? September 2002

  • W3C architecture for web services

    • Chose (gzipped) XML as opposed to other solutions for metadata descriptions… and web-based interfaces

  • linux

    • [as opposed to other platforms… lindows??]

  • C++ (experiments) and C, Java (middleware) APIs

    • [mono - Open Source implementation of the .NET Development Framework??]

    LCG Development

    – Long Term Attachment at CERN

    This will enable Grid developments in the UK to be (more) fully integrated with long-term Grid development plans at CERN.

    The proposed mechanism is:

    1. submit a short one-page outline of current and proposed work, noting how this work can best be developed within a named team at CERN, by e-mail to the GridPP Project Leader (Tony Doyle) and GridPP CERN Liaison (Tony Cass).

    2. This case will be discussed at the following weekly GridPP PMB meeting and outcomes will be communicated as soon as possible by e-mail following that meeting.


    1. The minimum period for LTA is 3 months. It is expected that a work programme will be typically for 6 months (or more).

    2. Prior DataGrid and LHC (or other) experiments' Grid work are normally expected.

    3. It is worthwhile reading

    in order to get an idea of the areas covered, and the emphasis placed, by the LCG project on specific areas (building upon DataGrid and LHC experiments' developments).

    4. Please send all enquiries and proposals to:

    Tony Doyle <> and

    Summary of lcg presentation

    Summary of LCG presentation

    Tony Cass

    • Project got under way early this year

    • Launch workshop and early RTAGs give good input for high-level planning …

    • … to be presented to LHCC in July

    • New plan takes account of first beam in 2007

    • No serious problems foreseen in synchronising LCG plans with those of the experiments

    • Collaboration with the many Grid projects needs more work

    • Technical collaboration with the Regional Centres has to be established

    • Recruitment of special staff going well (but need to keep the recruitment momentum going)

    • Very serious problem with materials funding

    6. DataGrid

    • The most important criterion for establishing the status of this project was the European Commission review on March 1st 2002.

    • The review report of project IST-2000-25182 DATAGRID is available from PPARC.

    • The covering letter states “As a general conclusion, the reviewers found that the overall performance of the project is good and in some areas beyond expectations.”

    • The reviewers state “The deliverables due for the first review were in general of excellent quality, and all of them were available on time… All deliverables are approved. The project is doing well, exceeding expectations in some areas, and coping successfully with the challenges due to its size.”

    • See Andrew and John’s talks..

    • LCG is the proposed mechanism by which the EDG testbed at CERN becomes an LCG Grid Service. The evolution of the EDG testbed to the LCG Grid Service will take account of both EDG and US grid technology. Need to take account of this..

    9. Interoperability

    • How do we integrate with developments from elsewhere in order to ensure the development of a common set of principles, protocols and standards that can support a wide range of applications?

    • GGF…

    • Within the Particle Physics community, these ideas are currently encapsulated(??) in the Grid Laboratory Uniform Environment (GLUE).

    • Recommend this as a starting point for the wider deployment of Grids across the Atlantic. See (Ruth Pordes et al.)

    A vision is only useful if its shared

    Grid success is fundamental for PP

    Scale in UK? 0.5 Pbytes and 2,000 distrib. CPUs? = GridPP in Sept 2004

    Integration – ongoing..

    Dissemination – external and internal

    LHC Analyses – we’re getting there..

    Other Analyses – ditto - look forward to Roger’s talk

    DataGrid - - major investment = must be successful

    LCG – Grid as a Service

    Interoperability – sticky subject

    Infrastructure – Tier-A/1 in place, Tier-2’s to follow…

    Finances – (very well) under control

    Next steps on framework 6..

    CERN = EU’s e-science centre

    Co-operation required with other disciplines

    Monitoring mechanisms in place…

    Emphasis on deliverables
