Introduction

The DAQ/HLT plots below from collision periods in 2010, 2011 and 2012 are approved to be shown by ATLAS speakers at conferences and similar events.

Please do not add figures on your own. Contact the DAQ project leader in case of questions and/or suggestions.

Distribution of processing time per event in the Event Filter farm in July 2012.
Each color corresponds to a family of processors
black: older CPU model; red: older CPU model, SMP on; green: newer CPU model.
The average processing time for each family is shown in the box.

CPU Usage in the Event Filter farm, as a function of the luminosity in 2011.
Each point corresponds to the peak of the CPU usage averaged over the entire EF farm, for a specific run;
the peak corresponds in time to the highest luminosity at beginning of the fill.
The points are indicatively grouped per different trigger menus.

Notes

Data Taking Efficiency

The weekly averages of three independent quantities: ATLAS Run Efficiency, ATLAS Run Efficiency while Ready for Physics and stable beam availability.. Note that the efficiencies are not luminosity weighted. The Run Efficiency is defined as the ratio of the running time during beam time to beam time. The running time incorporates the dead time fraction during each Luminosity Block reported by the Central Trigger Processor. The beam time is defined by the presence of two circulating stable beams. The width of each bar represents a week in which the availability of stable beams are shown with the red histogram with the scale on the right hand side. The average run efficiency calculated during each week is shown by the filled green (ATLAS is running) and grey (ATLAS is running while Ready for Physics) histograms. The absence of a bar in the plot indicates a week with no stable beams.
