Description
Since 2022, the LHCb detector is taking data with a full software trigger at the LHC proton-proton collision rate, implemented in GPUs in the first stage and CPUs in the second stage. This setup allows to perform the alignment & calibration online and to perform physics analyses directly on the output of the online reconstruction, following the real-time analysis paradigm.
This talk will focus on the first level of the LHCb trigger implementation on GPUs, discuss challenges of using a heterogeneous architecture and report on the experience from the first running periods in 2022 and 2023.
