World’s largest spreadsheet™ Recent copy on http://www.hep.man.ac.uk/~roger/babarspreadsheet.xls (provisional and not to be taken as definitive at this stage) Sheet 1: Notes Will answer some of your questions Sheet 2: LumChart This sheet intentionally left blank Sheet 3: Luminosity Best estimates of future Lumi and running time Sheet 4: Inputs Combines Luminosity with cross sections, MC requirements, event sizes, processing times etc to get total disk and CPU needed Sheet 5: AnalysisII Needs for analysis (using data from Inputs) Sheet 6: Production II Needs for production (using data from Inputs)
The next 5 pages Sheet 7: Unit costs. Of all components. Including Moore’s Law. NB this is based on what it would cost at SLAC Sheet 8: EffectiveSubsystemCosts Of extra bits needed to put components together to form a subsystem Sheet 9: CostsII Summary of system costs Sheet 10: Tier A How CPU and disk is split between the various Tier A sites. (This is where the MoU numbers come from.) Sheet 11: Funding II This is the financial information that determines the common fund and the rebate. Note UK fraction determined as 40/424.
