Description

This book constitutes the refereed post-conference proceedings of the 5th International Workshop on Accelerator Programming Using Directives, WACCPD 2018, held in Dallas, TX, USA, in November 2018. The 6 full papers presented have been carefully reviewed and selected from 12 submissions. The papers share knowledge and experiences to program emerging complex parallel computing systems. They are organized in the following three sections: applications; using openMP; and program evaluation. Front Matter ....Pages I-IX Front Matter ....Pages 1-1 Heterogeneous Programming and Optimization of Gyrokinetic Toroidal Code Using Directives (Wenlu Zhang, Wayne Joubert, Peng Wang, Bei Wang, William Tang, Matthew Niemerg et al.)....Pages 3-21 Using Compiler Directives for Performance Portability in Scientific Computing: Kernels from Molecular Simulation (Ada Sedova, Andreas F.
