New Initiatives inside NL
NCFGrid
strengthening Grid Infrastructure in NL
• 4 partners (NIKHEF, ASCI, SARA, ASTRON)
• 600 kEUR funding
• hardware (3 clusters, 10Gb/s networking)
and people (1.5 FTE over 3 years)
• fabric research + production-quality grids
• approved August 2002
First cluster assembled and being tested…
New Initiatives inside NL (2)
Virtual Laboratory for e-Science
in planning stage
O (50 MEUR)
Dutch “knowledge infrastructure” project
• Higher-level services to efficiently use global resources
• Both “bottom-up” and “top-down” in same project
• 14 partners, 6 application domains
• middleware research programme

Summary
• DutchGrid Platform started informally in 2000
• de-facto focus for Grid computing in NL
• Full centre,
operations (CA, web, …) supported by partners
• mix of people from all ‘layers’
networks, fabrics, security&AAA, prog. environments,
HPC visualisation, semantic DBs, applications
• Collaboration between users and providers
leads to great opportunities …
