Paper presentation at HPCS 2017

28/07/2017 13:26

Rodrigo Rocha, one of the coauthors of the work of Alyson Pereira, presented the paper entitled Extending OpenACC for Efficient Stencil Code Generation and Execution by Skeleton Frameworks at the International Conference on High Performance Computing & Simulation (HPCS) in Genoa, Italy. This work was advised by Prof. Márcio Castro.

In this work, Alyson proposed OpenACC extensions to enable efficient code generation and execution of stencil applications by parallel skeleton frameworks such as PSkel. The results show that our stencil extensions may improve the performance of OpenACC in up to 28% and 45% on GPU and CPU, respectively.
