This flag indicates how DistGrid elements are decomposed over DEs.
Values are:
- DEFAULT = 0
- Use default decomposition behavior. Currently equal to ‘BALANCED’.
- BALANCED = 1
- Decompose elements as balanced as possible across DEs. The maximum difference in number of elements per DE is 1, with the extra elements on the lower DEs.
- RESTFIRST = 2
- Divide elements over DEs. Assign the rest of this division to the first DE.
- RESTLAST = 3
- Divide elements over DEs. Assign the rest of this division to the last DE.
- CYCLIC = 4
- Decompose elements cyclically across DEs.
