Description
We discuss an approach for using commercial graphic processors (GPUs) at
the earliest trigger stages in high-energy physics experiments, and study its
implementation on a real trigger system in preparation.
In particular we focus on the possibility to reconstruct rings in a
Cherenkov detector as building block of a selective trigger condition for
rare decay search.
Latency and processing rate measurements on several state-of-the-art
devices are presented, and the potential issues related to processing
time jitter and data transfer throughput are discussed.
