Hi,
I would like to ask some comments about a small piece of code that
reflect many algorithms in a large application I try to move to openACC
with gfortran. This code manage a pointer to a user defined type with an
allocatable.
I've no problem to allocate and work with this type on the cpu

Hi everyone!
For several days I have some trouble with OpenACC offloading and fortran
pointers. I'm testing with a very small peace of code to investigate but
I do not progress for several days and I need your help.
The attached code goal is just to initialize some data on the GPU and is
.
There is a devel/omp/gcc-12 branch you might want to try. I don't know
how different that branch is wrt openacc.
HTH,

Hi Harald
as I said, it is a large, massively parallel fortran code: more than 700
files, some with several thousands of lines. It could be difficult to
create a small reproducer but I will try if the problem is not known as
an other git branch of this code also create an internal error on
Hi,
I have built this morning the latest gfortran from a git clone:
GNU Fortran (GCC) 13.0.1 20230421 (prerelease)
I'm trying this compiler on a large and complexe Fortran90 code with
offloading using OpenACC.
At this time:
- code compiles with nvfortran and runs on A100 GPU.
- code
Hi,
my goal is to move a large fortran90 modular code to fortran 2008 using
the submodule concept. As I have nearly 400 files to modify I would like
to know if a tool exist to automatically extract variables from
fortran90 modules and build interfaces for subroutines and functions ?
