High throughput data analysis
• Analysing the data
– Large ensemble calculations (100’s10,000’s jobs)
– Complex workflows – dependent on previous steps
• High Throughput
– Exploit distributed computing and storage resources
Data replicated (multiple locations)
Resources selected through a broker
• WMS: Workload Management System
• Higher level tools: GANGA, DIANE, ...
– Information system records the available resources
– File catalogue records the location of replicated files
• Data stored in files
– Growing interest in relational data access
– Stored on tape (long-term) or disk (immediate access)
