Stencil computations are widely used for solving Partial Differential Equations (PDEs) explicitly by Finite Difference schemes. The stencil solver alone -depending on the governing equation-can represent up to 90% of the overall elapsed time, of which moving data back and forth from memory to CPU is a major concern. Therefore, the development and analysis of source code modifications that can effectively use the memory hierarchy of modern architectures is crucial.
