Description
This submission describes revised plans for Event Filter Tracking in the upgrade of the ATLAS
Trigger and Data Acquisition system for the high pileup environment of the High-Luminosity
Large Hadron Collider (HL-LHC). The new Event Filter Tracking system is a flexible,
heterogeneous commercial system consisting of CPU cores and possibly accelerators (e.g.,
FPGAs or GPUs) to perform the compute-intensive Inner Tracker charged particle
reconstruction. Demonstrators based on commodity components have been developed to
support the proposed architecture: a software-based fast tracking demonstrator, an FPGA-based
demonstrator, and a GPU-based demonstrator. Areas of study are highlighted in view of a final
system for HL-LHC running.
