--- Comment #19 from Toon Moene <toon at moene dot org> --- 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 used. However, this could well be because I do not do the distribution of the configuration values to the images other than 1 correctly. If you see any shortcoming here I would be very interested in the analysis. In any way, you can use this test case as you see fit - I wrote this in 2018 specifically to test the native coarrays ...
