description: In particle physics, a trigger is a system which uses criteria to decide which events from detectors are to be kept, discarding the rest. Presently, a vast majority of physics experiments rely on a hardware trigger implementation, with some employing the use of a "high-level trigger" on top of the hardware implementation. A high-level trigger normally entails online reconstruction of physics events in order to further assist with the filtering process. A significant downside of a hardware implementation of a trigger system is that such a system is only able to utilize signal from low-latency detectors in order to perform decisions. With recent technology developments, the creation of a "trigger-less" data acquisition system is becoming increasingly feasible. Such a system would only make use of a high-level trigger to filter the events. The Ph.D. candidate will be tasked with designing universal architectural patterns for such a system, as well as the underlying scheduling and data-flow managing algorithms. After designing a fitting general solution, he or she will also be tasked with the implementation of such a system for a selected physical experiment.
