Estimated total disk resources (in PBytes) needed for the years 2018 to 2028 for both data and simulation processing. The blue points are estimates based on the current event sizes estimates and using the ATLAS computing model parameters from 2017. The solid line shows the amount of resources expected to be available if a flat funding scenario is assumed, which implies an increase of 15% per year, based on the current technology trends. diskHLLHC.png

The dependency of reconstruction wall time per event on the average number of interactions per bunch crossing is shown. The plot contains a selection of Tier-0 jobs reconstructing RAW data from 13 TeV pp LHC collisions in 2017. Each reconstruction job was required to run on one core of a 16-core machine with Intel(R) Xeon(R) CPU @ 2.40 GHz and memory of 4 GB/core. The red boxes refer to a special high-mu run 335302. Reconstruction jobs were configured to produce only AOD outputs, whereas standard jobs proceeded with 12 additional output types (different DRAW, DESD, DAOD and HIST), which take extra processing time. mu_walltime_fit_combined2.png

The dependency of reconstruction wall time per event on the average number of interactions per bunch crossing is shown. The plot contains a selection of Tier-0 jobs reconstructing RAW data from 13 TeV pp LHC collisions in 2017. Each reconstruction job was required to run on one core of a 16-core machine with Intel(R) Xeon(R) CPU @ 2.40 GHz and memory of 4 GB/core. An exponential fit (yellow dashed line) to the typical collision runs (blue scatter plot) is being compared with the performance in special high-mu run 335302 (red boxes). The high-mu run jobs were configured to produce only AOD outputs, whereas standard jobs proceeded with 12 additional output types (different DRAW, DESD, DAOD and HIST), which take extra processing time.
