--- Comment #4 from afernandez at odyhpc dot com --- The code can be downloaded from GitHub: git clone https://github.com/MPAS-Dev/MPAS-Model cd MPAS-Model git checkout atmosphere/v6.x-openacc My experience with OpenACC is limited as I participated in a workshop 3 years ago but haven't used it since then. Yesterday I began to read some documentation (to refresh my memory) and the OpenACC 2.6 reference guide (https://www.openacc.org/sites/default/files/inline-files/OpenACC%20API%202.6%20Reference%20Guide.pdf) led me to think of this contruct as a standard one. Could this be an enhancement of 2.6 versus 2.5? If this were the case, would moving GNU from version 9 to 10 help? I'm unfamiliar with the PGI compilers so someone else might be able to chime in and shed some light on any PGI implementation.
