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 tiling techniques to the contex...

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...

Static LU Decomposition on Heterogeneous Platforms

In this paper, the authors deal with algorithmic issues on heterogeneous platforms. They concentrate on dense linear algebra kernels, such as matrix multiplication or LU decomposition. Block-cyclic distribution techniques used in ScaLAPACK are no longer sufficient to balance the load among processors running at different speeds. The main result of this paper is to provide a static data distribu...
