Yes, I am now convince this works (64 leads to stop 1, but 63 works).
Note that I slightly changed the program today, to add a sync all before the
forecasting loop, and adding one to the copy_local_to_global

After 00c2e5d1c15c67fc2c9d9ed86bfa1f5aa13848cc ,
the segfault for too many images is now also fixed,
and your program runs as expected.
I'd say an important milestone has been reached :-)

BTW, the speed difference between the native and the OpenMPI based program is
staggering. For a 936x770x60 grid, the native run takes around 14 seconds
elapsed time, while the OpenMPI based one takes 2 minutes

And I can reproduce the GFORTRAN_NUM_IMAGES=64 segfault:

--- Comment #23 from Toon Moene ---
The segfault at GFORTRAN_NUM_IMAGES=64 might be due to the fact that the
program doesn't contain a check whether the size of the boundary relaxation
zone (currently set to 4) is too large for the slabs.

Hi Toon,
it took some time, but we finally figured out that it is actually
a bug in your program that is causing problems.
It has (shortened)
nxglobal = 72;
This sets the coarray nxglobal to 72 on every

Thanks.
It works now for export GFORTRAN_NUM_IMAGES=1..10 for me.
Unfortunately, when I want to change the nxglobal and nyglobal values in the
domain via the namelist, sometimes the "default" values are

I agree - the coarrays should be the same size and the program should just only
*use* the part that it needs.
I also got an error with the caf-mpi library, but that one was impossible to
understand (in fact,
