Tailslayer: Library for reducing tail latency in RAM reads (github.com)

Tailslayer is an open-source C++ library designed to reduce tail latency in RAM reads by issuing “hedged” reads across multiple replicas stored on different DRAM channels with uncorrelated refresh behavior. It replicates data across channels using AMD/Intel/Graviton-compatible channel scrambling offsets, then returns the first completed replica while the library performs follow-up work on the winning value. The repo includes example code and supporting benchmarks/probes to characterize DRAM refresh timing.
