A converged architecture for processing 32 Tbps of physics data in real-time at the LHCb experiment
Roel Aaij, Christina Agapopoulou, Thomas Boettcher +27
The LHCb detector at the Large Hadron Collider has been upgraded to acquire an unprecedented 32 Tbps of particle-collision data to provide new insights in the High Energy Physics d…
Seeding and Matching algorithms for the first GPU-based High Level Trigger of the LHCb experiment
Christina Agapopoulou, Lukas Calefice, Ãlvaro Fernández Casani +10
We describe the GPU implementation of the Seeding and Matching algorithms, developed for the first level trigger of the LHCb experiment and key to reconstruct long and very displac…
Energy efficiency of a GPU-based computing system for High Energy Physics experiments
Jiahui Zhuo, Arantza Oyanguren, Ãlvaro Fernández Casani +3
In this paper we introduce the energy efficiency as a new metric for evaluating both hardware platforms based on Graphic Processor Units (GPU), and algorithm optimisations at High…
A Downstream and vertexing algorithm for Long Lived Particles (LLP) selection at the first High-level trigger (HLT1) of LHCb
V. Kholoimov, B. Kishor Jashal, A. Oyanguren +2
A new algorithm has been developed at LHCb which is able to reconstruct and select very displaced vertices in real-time at the first level of the trigger (HLT1). It makes use of th…
LHCb potential to discover long-lived new physics particles with lifetimes above 100 ps
Volodymyr Gorkavenko, Brij Jashal, Valerii Kholoimov +6
For years, it has been believed that the main LHC detectors can only restrictively play the role of a lifetime frontier experiment exploring the parameter space of long-lived parti…
