Static tiling for heterogeneous computing platforms

In the framework of fully permutable loops, tiling has been extensively studied as a sourceto-source program transformation. However, little work has been devoted to the mapping and scheduling of the tiles on physical processors. Moreover, targeting heterogeneous computing platforms has to the best of our knowledge, never been considered. In this paper we extend static tiling techniques to the ...

Analyzing power efficiency of optimization techniques and algorithm design methods for applications on heterogeneous platforms

Graphics processing units (GPUs) have become widely accepted as the computing platform of choice in many high performance computing domains. The availability of programming standards such as OpenCL are used to leverage the inherent parallelism offered by GPUs. Source code optimizations such as loop unrolling and tiling when targeted to heterogeneous applications have reported large gains in per...

Tiling and Scheduling of Three-level Perfectly Nested Loops with Dependencies on Heterogeneous Systems

Nested loops are one of the most time-consuming parts and the largest sources of parallelism in many scientific applications. In this paper, we address the problem of 3-dimensional tiling and scheduling of three-level perfectly nested loops with dependencies on heterogeneous systems. To exploit the parallelism, we tile and schedule nested loops with dependencies by awareness of computational po...
