EU Infrastructures
• Géant network
• e-Infrastructure has 3 projects:– EGEE:
• interconnecting small/medium computing facilities– DEISA:
• network between existing supercomputer sites– OMII-EU
• extension of OMII-UK; develop middleware for Grid– some Periphery projects
• taking advantage of the infrastructure

Other Issues
• EuroVo:– integration of off-the-shelf software– procedure for software development to certification
quality
• pyramid structure:– national/local facilities to communicate with
European-level facilities to be developed– European facilities should have resources larger than
those currently available at HPC sites

LHDL
• started Feb 2006
• exemplar for community building/collaboration
• storage & computing services– professionally managed– looking for sustainable model

Questions/Remarks
• new environments unfriendly to users
• users should have greater support
• staff available at supercomputer centre specialised to particular fields
• recognise that user should feel comfortable– they want the “look” of their familiar software– difficult with specialised software
• need layer to support more general user
• EC is currently supporting recent projects to address this problem

Integrated Software Environment
• data capture
• imaging
• modelling
• simulation
• interpretation
• intervention
• variety of visualisation techniques

Questions/Remarks
• how to ensure that the representation is accurate?
• little done so far in relation to uncertainty in visualisation – needs work
• users continue to use outdated algorithms – possibly because later algorithms are more complex
• making different software modules work together remains a challenge– need common component architecture
• too much code is produced to low software engineering standards

Common Objectives
• support community building
• provide user-specific access tools
• develop production-strength semantic representations of the VPH and of the infrastructure (Semantic Grid)
• develop robust backend services for:– user authentication– access to VPH resources (data services, simulation
services)– publication of VPH Resources– federation of repositories

Research Challenges
• VPH portal (Biomed Town?)
• frameworks and toolkits for fat clients development
• semantic resource brokers
• tools for collaborative maintenance of ontologies
• software architecture for semantic representation of storage resources
• software architecture for sharing and reuse of simulation resources
• toolkits for wrapping of storage and simulation resources into web services
