We demonstrate that the performance of commodity parallel systems significantly depends on low-level details, such as storage layout and iteration space mapping, which motivates the need for tools and techniques that separate a high-level algorithm description from low-level mapping and tuning. We propose to build a tool based on the concept of decoupled Access/Execute metadata which allow the programmer to specify both execution constraints and memory access pattern of a computation kernel.
