© 2006 STEP Consortium 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

© 2006 STEP Consortium 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

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

© 2006 STEP Consortium 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

© 2006 STEP Consortium 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 little done so far in relation to uncertainty in visualisation – needs work users continue to use outdated algorithms –possibly because later algorithms are more complex making different software modules work together remains a challenge –need common component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
