Data-layout Optimization for Stencil codes on multi-cores and GPUs

Participants : Julien Jaeger, Denis Barthou.

• We develop a new approach for stencil code generation, optimizing data-layout for multi-threaded, SIMD code on multicores and CUDA code on GPU. The transformation handles different stencil parameters, and memory constraints.

• The code generated reaches high levels of performance, outperforming related works for multicores and with similar performance on GPUs. This work is submitted to publication and was first presented in a workshop  [52] .
