        The ATLAS EventFilter System - Reconstructing Tracks online with the ATLAS Phase-II Trigger System 1h

        The upcoming high-luminosity phase of the LHC (HL-LHC) presents several challenges for the ATLAS experiment's Trigger and Data Acquisition system, necessitating a full upgrade of the system. A key challenge for the Event Filter, where high-level event reconstruction and final event selection will run at 1 MHz, lies in the computational demand for online track reconstruction within the Inner Tracker.
        Over the past few years, extensive research has been conducted into utilising hardware accelerators in the ATLAS Event Filter system to improve tracking throughput and reduce full-system power consumption. Various end-to-end track reconstruction pipelines have been developed using GPUs and FPGAs. These pipelines demonstrate their capabilities by offloading different amounts of the computing load to the accelerators.

        This seminar will give an overview of the different solutions utilizing different computing hardware for tracking with a focus on developments in FPGA-based track reconstruction pipelines integrated into the ATLAS software framework, Athena.
