The GridCast Project Grid based Broadcast Infrastructures France-UK N+N November 2003 4
The Grid Scenario: The BBC Nations BBC NI, BBC Scotland and BBC Wales • BBC Nations provide customised services in each nation • Television programmes are distributed to BBC Nations from BBC Network (London) using dedicated leased ATM circuits . France-UK N+N November 2003 5
Grid Infrastructure • Technical – High-bandwidth network connections inter- connect broadcast locations. – Network bandwidth means geography is less of an issue. • Organisational – Less centralised France-UK N+N November 2003 6
Overview • To develop a baseline media grid to support a broadcaster – Manage distributed collections of stored media – Prototype security and access mechanisms – Integrate processing and technical resources – Integrate with media standards and hardware • To analyse Quality of Service issues – Analyse remote content distribution infrastructures – Analyse remote service provision – To analyse reactivity, reliability and resilience issues in a grid-based broadcast infrastructure France-UK N+N November 2003 7
Characteristics • Stored media files are Gbytes and increasing – 1 hour ~ 200 Gbytes; distributes 1 petabyte /year • Management and distribution is significant technically • Metadata – location, timings, artists, storage formats etc. is an integral part of broadcast structure • Content is a valuable commodity – access, modification, copying must be controlled • High levels of quality required France-UK N+N November 2003 8

Scenario • A Network Schedule is defined – This schedule is the framework for Nation schedules • Network Schedules are distributed to BBC Nations – Usually via email • BBC Nations formulate their schedule • A Schedule is Broadcast – By programming local network and content control automation France-UK N+N November 2003 12
Model of Broadcast • Automatic distribution of broadcast schedules – Management of schedule archives – Automatic notification • Content is copied from archives to local content storage – Content distribution defined by schedule France-UK N+N November 2003 13
Broadcast grid issues • Business change – A revised organisational model. Services and resources Each broadcast location gains control….no network schedule . – • Resilience – Resource sharing and no single programme repository – A BBC Nation can be anywhere! • Reliability Use resources available in other BBC sites or from 3 rd party suppliers – • Cost – Better use of resources and less need for backup resources – Less dependence on particular vendors or suppliers • Customisation – Schedule, local resources, local capabilities • Interoperability – Business model facilitates sharing with other broadcasters France-UK N+N November 2003 14
RiskGrid Grid Financial Services France-UK N+N November 2003 15
Background • Financial sector largely cyclical • Risk assessment calculations Investment Bank (US) Investment Bank (EU) Investment Bank (ASIA) … Traders…. … Traders…. … Traders…. Corporate Intranet France-UK N+N November 2003 16
Backgroun d • Depends heavily on calculations for competitive advantage – Compute intensive • Large amount of financial derivatives calculations – Data intensive • Data-access, bottleneck. 2Gb transactions/day on NYSE • Improve performance – Increase accuracy of potential risk in trade – Direct impact on margins – 1% improvement - $$$ France-UK N+N November 2003 17

Issues • Business Change – Attempt to give real time risk assessment • Performance – Harnessing resources to suit the problem • Cost – Use utility and/or unused in-house resources • Resilience – Not restricted to locally available resources • Interoperability – Provide gateways to other services or service provides France-UK N+N November 2003 19
GEDDM G rid E nabled D istributed D ata M ining and Conversion of Unstructured data France-UK N+N November 2003 20
Background • Fuzzy parallelised data-matching and transformation engine • Forensic accounting, banking, anti- terrorist, crime • Clusters: PC, Linux, supercomputers • Large volumes data France-UK N+N November 2003 21
GEDDM: Business Driver • Data sources – numerous structures, formats, locations administrative domains… • Client – US County Court: insider trading litigation case • 45Tb • Email, pdf, weblogs, RDBMS, Word, files … • How to process this data to achieve ? – Meaningful outcomes quickly – Handling multiple formats with common semantic model France-UK N+N November 2003 22
Issues • Performance – Use utility computing to improve performance • Cost – Reduce internal need for high performance computing – Reduce the need to provide on-site services • Business change – Provide a secure online automated service to companies • Resilience – Reduce reliance on internal computing resources • Interoperability – Provide mining engine as a service to other services France-UK N+N November 2003 23
GeneGrid A Virtual Bioinformatics Laboratory France-UK N+N November 2003 24
GeneGrid – Fusion Antibodies Ltd : – Amtec Medical Limited: • US – NIH, Washington • Business drivers: – Develop specialist tissue specific datasets – 3 sites, little collaboration – No dedicated HPC, low bandwidth – Economic advantage (peak demand/supply min) – MicroArray, Seq, Large volumes data… France-UK N+N November 2003 25
GeneGrid • Solution – Grid Service based architecture – Protect confidentiality – Security Model – Genome database integration • Diagnosis – Screening protocols aid customised drug targeting – Gene expression profile • Dataset Mining – NI stable gene pool & complete patient records – Correlation against various target populations France-UK N+N November 2003 26
