Abstract: We discuss the challenges that real-time radio transient surveys face from the perspective of one of the projects currently scanning the sky. MeerTRAP is a commensal pulsar and fast transients survey that is being conducted using MeerKAT – a precursor to the Square Kilometre Array, consisting of 64 dishes in South Africa. The main goal of this project is to detect and localise fast radio transients, including FRBs, RRATs and pulsars as close to real time as possible. This requires search pipelines that are capable of both rapidly processing large amounts of data, on the order of hundreds of gigabits per second, and presenting the observer with output that can be easily analysed with as little delay as possible. We discuss solutions that form the backbone of modern transient pipelines, with an emphasis on GPU computing and multithreaded applications. We outline the roadmap for future developments, including current and future requirements with regards to faster and more efficient computing, and reducing the need for human intervention.
