Description
In order to maintain sensitivity to new physics in the coming years of LHC operations, the ATLAS experiment performing a number of trigger and detector upgrades. All new components will be read out via a newly developed system featuring an application called the Software Readout Driver (SW ROD), which will run on a commodity server receiving front-end data via the Front-End Link eXchange (FELIX) system. The SW ROD will perform event fragment building and buffering as well as serving the data on request to the High Level Trigger. The SW ROD application has been designed as a highly customizable high-performance framework providing support for detector specific event building and data processing algorithms at the expected input trigger rate of 100 kHz. This document will cover the design and the implementation of the SW ROD application and the results of performance measurements taken with the server models selected to host SW ROD applications in Run 3.
