The Allen project is simultaneously a framework for portable parallel computing, optimised for applications which require extreme throughputs, and the concrete implementation of LHCb's GPU-based first-level trigger system deployed in LHC Run 3. This talk will cover the genesis of Allen, its performance as a production application in Run 3, and discuss current efforts to refactor the experiment-independent parts of Allen (AllenCore) into a general-purpose high-throughput cross-architecture processing framework which can work together with other cross-experiment frameworks and libraries such as Gaudi and ACTS/Traccc.
