Combining the strengths of UMIST and The Victoria University of Manchester Use cases Stephen Pickles e-Frameworks meets e-Science workshop Edinburgh, 27/4/2006 Slide 2 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20062 NGS & Partners Today Slide 3 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20063 NGS Points to notice NGS provides compute and data resources to UK users and user communities based on PKI (mostly GSI) Care about making NGS relevant to wider community e.g. provisioning of domain-specific portals using NGS resources need to bridge AA universes this is the ShibGrid problem Care about making wider (e.g. JISC-funded) developments accessible in a Grid context e.g. access to centrally curated data in Grid workflows need to bridge AA universes in opposite direction this is the GridShib problem need services to be Web services (not just capabilities), and secure Web browser context is insufficient Slide 4 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20064 SHEBANGS Shibboleth-Enabled Bridge to Access the NGS Slide 5 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20065 ConvertGrid Services to automate extraction, geography conversion and fusion of aggregate, geography-based datasets.

This will involve connecting the SQLServer databases holding the 2001 Census data directly to the Grid via the NGS and also Grid enabling the current data access system (Casweb). The advantage of this approach is that it will maximise and build upon the ESRC/JISC investment in the establishment of existing data infrastructure, avoid having to maintain multiple database systems to support different forms of access and also provide a more rapid and flexible method of building Data Grids via the NGS. The project will be working closely with two of the National Centre for e-Social Science (NCeSS) nodes who have a requirement for grid enabled access to the aggregate statistics from the 2001 Census and who will be early adopters of the service. Slide 8 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20068 MIMAS & data provision Points to note: users must register to access many relevant datasets e.g. census, satellite data,... wealth of access control information in things like Athens, Shibboleth not readily accessible from Grid context this is the GridShib problem access enforced by data portals must shift to service layer to make grid-accessible Slide 9 Combining the strengths of UMIST and The Victoria University of Manchester 28 April 20069 Nektar, SPICE & Vortronics (2005) Funding from NSF (US) and EPSRC (UK) for projects linking TeraGrid and NGS Inspired by TeraGyroid Experiment (2003) All involve parallel codes and need high-bandwidth cross-site communication.
