IPU model is not fully replicating IPU hardware in the case of gather and scatter vertices, where the `splitSingleRegion` seems to be ignored on the IPU model. Setting back `splitSingleRegion=False` solves the issue. One still needs to investigate which configuration of these vertices is the most optimal.
