Future UK e-Science Grid Middleware :  Future UK e-Science Grid Middleware Dr Steven Newhouse London e-Science Centre Department of Computing, Imperial College London Contents:  Contents Grid Middleware UK e-Science Core Programme I & II LeSC Activities Status of the Grid:  Status of the Grid Today: ‘early adoption’ phase - just like the Web in the early days Tomorrow: sophisticated combinations of services to locate information, applications to process it, and computer systems to run them Requirements: Infrastructure to support: e-Science Virtual Organisations e-Commerce e-Utilities Exposing Resources as Services:  Exposing Resources as Services Permissible SLA COMPUTE RESOURCES SERVICE LEVEL AGREEMENT B A C D Defines: What? Who? When? SOFTWARE RESOURCES STORAGE RESOURCES Open Grid Services Architecture:  Open Grid Services Architecture OGSA addresses architectural issues related to broadly interoperable Grid Services. OGSI based on the GSS provides mandatory features, such as service invocation, lifetime management, a service data interface, and security interfaces. GT3 implementation of OGSI & equivalent GT2 services GT3 Jini Jxta GT2 OGSI UK e-Science Core Programme:  UK e-Science Core Programme From Tony Hey’s slides at EPSRC Pilot Project meeting (end of Jan 03) CP I: e-Science Centres & open calls CP II: Plans not promises as dependent on funding SR2002: £16M DTI: £??M Core Programme 2: Overall Rationale:  Core Programme 2: Overall Rationale Assist development of essential, well-engineered, generic, Grid middleware usable by both e-scientists and industry Provide necessary infrastructure support for UK e-Science Research Council projects Collaborate with the international e-Science and Grid communities Work with UK industry to develop industrial-strength Grid middleware Key Activities:  Key Activities UK e-Science Grid/Centres and e-Science Institute Grid Support Centre and Network Monitoring Core Middleware engineering National Data Curation Centre e-Science Exemplars/New Opportunities Outreach and International involvement The e-Science Grid/Centres and the e-Science Institute:  The e-Science Grid/Centres and the e-Science Institute Continuation of e-Science Centre’s & Institute 2 year extension for infrastructure after review Further development of UK e-Science Grid Collaborative Industrial Projects Call for DTI collaborative industrial projects targeted to key middleware areas Grid Support Centre & Network Monitoring Core Grid Middleware Activity:  Core Grid Middleware Activity Need to develop open source, open standard compliant, Grid Middleware stack that will integrate and federate with industrial solutions Software Engineering focus as well as R&D Aim is to produce robust, well-documented, re-usable software that is maintainable and can evolve to embrace emerging Grid Service standards Link UK activities with Europe & US Reduce duplication of effort Standards development & compliance testing Possible Core Grid Middleware Themes:  Possible Core Grid Middleware Themes Heterogeneous Database Integration Security Legal and regulatory Accounting Systems for VOs Collaborative Decision-making Networks Enterprise Computing Systems Outsourcing/e-Utilities Real-time High End Computing Enterprise Application Integration Business Processes for VOs Links to EPSRC CS Research?
