Error while building for OpenACC support with pgf90 21.3 #5
Comments

It seems that you are using different CFLAGS.
The openacc code is using nvidia's "managed memory" and must be compiled
with the flag "-ta=manage" or something equivalent.
Can you add this flag?

The issue has been resolved. Although this is a separate issue, I report here that the OpenMP version built with pgf90 crashes during remeshing on my machine. When built with gfortran, however, the OpenMP version works fine. |

Hi, I'm reporting an issue I ran into while trying to build geoflac with OpenAcc support.
I got pgf90 as a part of NVIDIA HPC SDK 21.3.
A working recipe for building geoflac with OpenACC would be much appreciated!
