  1. Grid@epcc Joining the dots

  2. Introduction The ideas of grid computing are everywhere even if the actual grids are not as pervasive The are many grid middleware packages with overlapping functionality No universal solution Each project requires some glue to tie components together Edinburgh - Tsukuba Workshop

  3. Outline • Three example projects at EPCC • OGSA-DAI • BEinGRID • ILDG Edinburgh - Tsukuba Workshop

  4. Challenges Diversity Data resource types, vendors, middleware, schema, meta data Scale Collections, formats, volumes, geographical, political and social distance Ownership On individual, group, and organisational levels Security Client, service and data owners Edinburgh - Tsukuba Workshop

  5. Sharing data Convert data into information Reveal new insights Scientific knowledge Business advantage Data mining across distributed data resources Exploit public and private data Open or closed communities Scientific collaborations Business partnerships Edinburgh - Tsukuba Workshop

  6. OGSA-DAI OGSA-DAI – 02/2002 – 07/2003 EPCC, NeSC, IBM, Oracle, NEReSC, eSNW DTI/EPSRC via UK e-Science Grid Core Programme DAIT (DAI-Two) – 10/2003 – 10/2005 EPCC, NeSC, IBM, NEReSC, eSNW DTI/EPSRC via UK e-Science Grid Core Programme 2 as part of the OMII-UK project OMII-UK – 11/2005 – 04/2009 EPCC, NeSC EPSRC OMII-UK extension – 04/2009 – 04/2010 EPCC, NeSC EPSRC Edinburgh - Tsukuba Workshop

  7. Workflows Activity output Target data resource Activity Convert query from French to English Convert data from English to French Run SQL query SELECT Country, Capital FROM Countries Join the data SELECT Pays,Capital FROM Pays SELECT País, Capital FROM Países Convert data from Spanish to French Convert query from French to Spanish Run SQL query Activity input Edinburgh - Tsukuba Workshop

  8. Advanced Data Mining and Integration Research for Europe EU 7th Framework program project EPCC, NeSC and European partners Infrastructure for data integration and mining Large scale enterprise systems Applications Flood modelling and simulations Customer relationship management ADMIRE Edinburgh - Tsukuba Workshop

  9. GEOGrid Global Earth Organisation (GEO) Grid National Institute of Advanced Industrial Science and Technology, Japan Geo-spatial data and services Disaster mitigation Environmental monitoring Natural resource exploration Virtual integration and access control Data Satellite imagery Geological data Ground-sensed data Edinburgh - Tsukuba Workshop

  10. SEE-GEO – geo-linking portal UK BORDERS MIMASCensus Maps 1: GLSQuery submited via portal e.g. “Leeds population distribution by census output area” GLS Portal 5: Portal gets image using URL 4: URL of image is returned to portal – avoids costly SOAP/HTTP transfer of image OGSA-DAI Get 3: Image is placed on a map server Join Transform Deliver Get 2: Workflow is populated with query parameters and run Image Creation Service Edinburgh - Tsukuba Workshop

  11. BEinGRID • Type of project: Integrated Project • Project coordinator: ATOS ORIGIN • Project start date*: 1st June 2006 • Duration: 42 months • Max EC contribution: 15.7 M euros • Consortium: 99 partners http://www.beingrid.eu/ http://www.it-tude.com/ Edinburgh - Tsukuba Workshop

  12. BEinGRID Vision • Typical Technology Transfer project: • 2 waves of 18+7 Business Experiments involving: • SMEs in various industry-sections • Technical and Business experts • Set up a repository of Grid solutions, available free/at cost to the respective sectors • Prove that businesses will benefit from the adoption of Grid technologies Edinburgh - Tsukuba Workshop

  13. BE02 – FilmGrid • “Movie post-production workflow” • Reviewing data flow in the industry • Current data movement tied into celluloid shooting • What is the effect of digital capture? • How useful is Sohonet other than for email? • The FilmGrid prototype proves: • Grid technology is highly appropriate for movie post-production • Potentially large gains in: • Efficiency • Reliability • Accountability • Accessibility • http://tinyurl.com/filmgrid Edinburgh - Tsukuba Workshop

  14. Asset Manager Local Files Transfer Status Global Assets Edinburgh - Tsukuba Workshop

  15. Database Triggers • Procedure to be executed when a modification is made to a table • INSERT, UPDATE or DELETE • Various use cases • Log changes • Execute business rules (e.g. email a manager when online orders push stock levels below a specified threshold) • Enforce business rules (e.g. all invoices must be associated with a valid customer) • How to set-up a trigger is dependent on DB implementation Edinburgh - Tsukuba Workshop

  16. OGSA-DAI Trigger • Uses database triggers to call an OGSA-DAI workflow upon modification to a database • Extends single-database trigger functionality to: • Span several, heterogeneous databases • Execute powerful OGSA-DAI workflows • Many possible use cases • Synchronising databases • Logging to an external database • Ensuring or executing business logic across partners http://tinyurl.com/ogsadaitrigger Edinburgh - Tsukuba Workshop

  17. BE24 – GRID2(B2B) • “Grid technologies for affordable data synchronization and SME integration within B2B networks” • Empowering existing B2B networks by electronically connecting suppliers at an affordable price • Webservices-based add-on to allow data exchange at database level • Uses OGSA-DAI Trigger to automate synchronization • The GRID2(B2B) prototype demonstrates: • Easy integration with multiple B2B platforms • User in total control of what data is sent • Automated synchronization: • Fast and frequent data transfer • Remove the need to enter data twice • http://tinyurl.com/grid2b2b Edinburgh - Tsukuba Workshop

  18. New orders generated by Ducati software DBMS GRID2(B2B) Data Service OGSA-DAI Trigger used to monitor for new data How does it work? Data Service and Data Federation Agent are configured using the GRID2(B2B) Configurator Data Service communicates the new information to the Data Federation Agent MaNeM – B2B Platform Ducati - Starter GRID2(B2B) Data Federation Agent Bentivogli - Partner DBMS Orders written to an internal database DBMS GRID2(B2B) Data Service Data Federation Agent inserts information into B2B database. Data Federation Agent also monitors for new data in the B2B platform and propagates it on to the correct member of the network Edinburgh - Tsukuba Workshop

  19. International Lattice Data Grid • Sharing Lattice QCD data • ILDG has no formal role • groups collaborate informally • working groups for metadata and middleware • Individual groups were already starting to build data grid infrastructures • UKQCD – QCDgrid, later DiGS • German groups combined into LATFOR, grid arm is LDG • US groups formed USQCD • Japanese – JLDG • Australia – Web portal • Middleware often dictated by national considerations • ILDG is an aggregation of existing grids • Interoperable Edinburgh - Tsukuba Workshop

  20. ILDG WG • Edinburgh and Tsukuba personnel • Metadata Working Group • Tomoteru Yoshie Previous Convener • Chris Maynard Current Convener • Middleware Working Group • George Beckett, Daragh Byrne, Eilidh Grant, Radek Ostrowski, and James Perry • Mitsuhisa Sato, Toshiyuki Amagassa, Osamu Tatebe • Example of Tsukuba and Edinburgh active collaboration Edinburgh - Tsukuba Workshop

  21. Three requisite conditions • Trust • already established in the community • known community • Altruism • political will to make data available • effort to build infrastructure • effort actually making data available • Reward • how to credit those making data available • data users should cite a designated paper Edinburgh - Tsukuba Workshop

  22. Three ideas to make this work • Standard data format • Doesn’t really matter what, as long as one can read and write • configurations: SciDAC LIME record is 3x3 NERSC data layout • Standard metadata • Semantic description of the data • Can be processed by an application • Standard interfaces to services • Queries to metadata catalogues (MDC) • Queries to File Catalogue Web services (FC) • Authentication and authorisation Edinburgh - Tsukuba Workshop

  23. Architecture Edinburgh - Tsukuba Workshop

  24. Summary • Rise in data complexity • doing things by hand is no longer scalable • we need tools to automate logistics and glue systems and data together • Grid architecture sits on top of existing systems • can access remote data with local tools • Many different middleware stacks • Effort required to ensure interoperability • Tsukuba and Edinburgh already collaborated successfully on ILDG Edinburgh - Tsukuba Workshop

  25. Lunch Edinburgh - Tsukuba Workshop
