Hi Alistair, Can you fix the coupled experiment you just break ? And the CPP_EEOPTIONS.h that are left because of exch_w2 (adjustment.cs-32x32x1 adjust_nlfs.cs-32x32x1 aim.5l_cs global_ocean.cs32x15 & hs94.cs-32x32x5) do not look like the standard one (eesup/inc) regarding the MPI stuff. Is it normal ? See you, Jean-Michel
