Evolution of the energy efficiency of LHCb's real-time processing
Roel Aaij, Daniel Hugo Cámpora Pérez, Tommaso Colombo +7
The upgraded LHCb detector, due to start datataking in 2022, will have to process an average data rate of 4~TB/s in real time. Because LHCb's physics objectives require that the fu…
A Comparison of CPU and GPU implementations for the LHCb Experiment Run 3 Trigger
R. Aaij, M. Adinolfi, S. Aiola +157
The LHCb experiment at CERN is undergoing an upgrade in preparation for the Run 3 data taking period of the LHC. As part of this upgrade the trigger is moving to a fully software i…
Allen: A high level trigger on GPUs for LHCb
R. Aaij, J. Albrecht, M. Belous +26
We describe a fully GPU-based implementation of the first level trigger for the upgrade of the LHCb detector, due to start data taking in 2021. We demonstrate that our implementati…
Improved performance of the LHCb Outer Tracker in LHC Run 2
Ph. d'Argent, L. Dufour, L. Grillo +36
The LHCb Outer Tracker is a gaseous detector covering an area of with 12 double layers of straw tubes. The performance of the detector is presented based on data of…
Tesla : an application for real-time data analysis in High Energy Physics
R. Aaij, S. Amato, L. Anderlini +18
Upgrades to the LHCb computing infrastructure in the first long shutdown of the LHC have allowed for high quality decay information to be calculated by the software trigger making…
Performance of the LHCb Vertex Locator
LHCb VELO Group, R. Aaij, A. Affolder +101
The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in the LHCb experiment. The performance of the detector during the fi…
