Automatic Generation of Multi-Objective Polyhedral Compiler Transformations

To this day, polyhedral optimizing compilers use either extremely rigid (but accurate) cost models, one-size-fits-all general-purpose heuristics, or auto-tuning strategies to traverse and evaluate large optimization spaces. In this paper, we introduce an adaptive and automatic scheduler that permits to generate novel loop transformation sequences (or recipes) capable of delivering strong performance for a variety of different architectures...
