Polyhedral optimization
Web•We provide the tool Polyite, which relies on LLVM’s polyhedral code optimizer Polly to model programs in the polyhedron model, apply tiling, and generate optimized code. Polyite is written in Scala [29]. •We reimplemented the search space construction of Pouchet et al. [33] and combined it with our sampling strategy.
