Putting Polyhedral Loop Transformations to Work, most appropriate transformations themselves. For that purpose, we need a?generic way to express program transformations and compositions of transformations. In this article, we introduce a?framework for the polyhedral representation of a?wide range of transformations in a?unified way. We also show

Improving the Performance of Morton Layout by Array Alignment and Loop Unrolling,for two-dimensional arrays. Morton layout offers some spatial locality whether traversed row-wise or column-wise. The goal of this paper is to make this an attractive compromise, offering close to the performance of row-major traversal of row-major layout, while avoiding the pathological behaviour o

Operation Reuse on Handheld Devices,cause it improves execution speed and energy efficiency at the same time. In a?broad view, redundancy exists in many different forms, e.g., redundant computations and redundant branches. We briefly describe our recent efforts to expand the scope of redundancy removal. We attain . by replacing a?code

Programming for Locality and Parallelism with Hierarchically Tiled Arrays,ions within single threaded programs. This, is then argued, facilitates reasoning about the resulting programs and stimulates the development of code that is highly readable and easy to modify. The new data type is illustrated using examples written in an extended version of MATLAB.
