  1. Large-Scale Distributed Computing in the Netherlands an overview David Groep, NIKHEF, 2003-01-20

  2. What is DutchGrid? • collaboration of 12 organisations • established in 2000 • functions as a platform, getting manpower & hardware from partner orgs • major contributors • NIKHEF • WTCWVirtual Laboratory Project (ICES/KIS-II) • ASCI (5 combined Dutch CS Faculties) • Foundation NCF (NWO)

  4. Resources • ASCI DAS-2 (VU, UvA, Leiden, TUDelft, Utrecht) • 200 dual P-III 1GHz CPUs • homogeneous clusters, 5 locations • NIKHEF DataGrid clusters • 75 dual P-III ~ 1GHz • 1Gb/s IPv4 + 1Gb/s IPv6 • NCF Gridnational computer facilities foundation from NWO • 66 node dual AMD-K7 Fabric Research Cluster (NIKHEF) • 32 node duals “production quality” cluster (SARA)* • 10Gb/s optical “lambda” test bed† • … • BioASP– various smaller O(10 node) clusters

  5. Resources (cont.) SARA – National HPC Centre • Processing • SGI 1024 processor MPP • Mass storage • StorageTek NearLine tape robot • currently: 500 TByte • will grow “indefinitely” (with funds from NCF) • User expertise centre In TotalOperations/deployment effort ~ 8 FTE availableResearch effort O (40 FTE) over 12 organisations

  10. 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…

Mngt Intg ExpEnvs UIs LSDS SecAAA Transport New Initiatives inside NL (2) in planning stageO (50 MEUR) Virtual Laboratory for e-ScienceDutch “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

  12. What is happening where in NL?

  13. DutchGrid Services • Authentication Services (Certification Authority) • EDG CACG “proper” CA • Student and educational CA • EDG “Tutorial” CA • Regular coordination and tutorials • Installation support • Distributing EDG software to other (HEP) sites • User support

  14. Principal Apps today • HEP: DØ, Atlas, LHCb, Alice, BaBarMonte-Carlo and Analysis • OPERA– ozone monitoring • WTCW Virtual Laboratoryvisual analysis environment for (small-scale) experimental science • Chemo-physical surface analysis (PIXE,FT-IR,SIMS) • BioASP – correlating “omics” databases • Virtual Surgery (planning by-passes, artery repairs) • EcoGridcorrelating bio-diversity information databases • Radio AstronomyLOFAR, AVO, VLBI – semi-online and offline processing

  15. Research Areas in NL • High-bandwidth networkingSURFnet, UvA, SARA, NIKHEF • Generic AAA and `security’UvA, NIKHEF • Cluster, Storage Management & MonitoringNIKHEF, SARA • Adaptive programming environmentsFree University Amsterdam • Memory-processor co-allocation TU Delft • Federated Information & Content ManagementUvA • Interactive visualisationCWI, UvA

  16. 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 …
