摘要：
Allen, LHCb’s GPU-based software trigger, operates LHCb’s High Level Trigger 1 (HLT1) system. It processes the LHCb’s full detector readout at 30 MHz, at a data rate of 4 Tb/s, on a computing farm of about 500 GPUs. This makes LHCb one of the world’s first high energy physics experiment to operate without a hardware trigger. Today, I will present Allen, discussing how the framework was designed to meet the demanding physics and computing performance requirements. I will also cover LHCb’s operational experience in successfully taking data with this trigger, as well as our future plans.
报告人简介：
Da Yu Tou received his PhD from Sorbonne University in 2020, focusing on test of lepton universality in b->sll decays at the LHCb experiment. Now a postdoctoral research at Tsinghua University, his recent research has centered around hadron spectroscopy via amplitude analysis and LHCb’s Real-Time Analysis (RTA) software trigger, specializing in its GPU-based High Level Trigger 1 (HLT1). He currently serves as a convener for the LHCb B-hadrons and quarkonia physics working group and is a convener for the HEP Software Foundation (HSF) in the Reconstruction and Software Triggers activity area.
