memory allocation in interior and exterior cellls
 

Hey!
I have a question concerning User Defined Functions (UDF) in parallel:

Since the exterior cells of one compute node are the interior cells of another compute node, do they also share the same data?
So if I change the temperature C_F of an exterior cell in one compute node, does this automatically change the temperature of the same cell in the adjacent compute now?
Or is there a separate memory allocation?

Thank you really much for your help, your support and your time!!!
Best regards
