Tool Integration for Source-Level Mixed Precision

Mixed-precision computing offers potential data size reduction and performance improvement at the cost of accuracy, a tradeoff that many practitioners in high-performance computing and related fields are becoming more interested in as workloads become increasingly communication-bound. However, it can be difficult to build valid mixed-precision configurations and navigate the performance/accuracy space without the help of automated tools. We present FloatSmith, an open-source, end-to-end source-level mixed-precision tuner that incorporates several software tools (CRAFT, TypeForge, and ADAPT) into an integrated tool chain.
