Resource Sharing Dilemma Secure Operation Fair Distribution Maximum Utilization Driving Requirement Design Enabler Scalable Efficiency 3
Grid Research Trends Open Grid Services Architecture (OGSA) Based Technology Adoption IBM/Globus, GGF, OASIS Grid services and Web services united in powerful ubiquitous core infrastructure - from academic research labs to mainstream industry and society Challenges: economic sustainability, secure crossdomain operation, semantic knowledge-aware interoperability New service and business models: utility computing, autonomous computing, dynamic QoS-driven SLA negotiation 4
Connecting National Computing Resources in SweGrid SweGrid connects 600 compute nodes across 6 Swedish HPC centers into a national Grid Resource quotas allocated by Swedish National Allocations Committee (SNAC) after peer-review of promising research projects with high computational demands Heterogeneous scheduling, security, and accounting environment (policies, tools, data, processes, etc) Wanted: Uniform resource use & allocation 5
