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

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.

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,
