Delivering Data: Insights and Progress from CERN's Information Technology Department

On April 14, 2010, Tony Cass, the leader of the Database Services Group at CERN, presented a comprehensive overview of the current state of data delivery at CERN. This presentation provided insights into the challenges faced in data distribution, the progress made, and the future direction for data management at the facility. Acknowledging contributions from key CERN personnel, the talk outlined the difficulties in data accumulation and the operational strategies in place to enhance data flow and processing in high-energy physics experiments.

  9. Physics 48 h • We can produce long fills but we did not manage to have a programmed dump yet • Beam lifetime is excellent (>100 h) • From LHC Physics Coordinator @ LMC (07/04/2010): • Accumulated order of 300 mb-1/expt • Several million inelastics on tape • Inelastic rates typically up to ~120 Hz when optimized and ~1.1e10 p/bch, small emittance • Luminosity life time seen well above 20h !
