Null
For a collective operation, indicates that this process is the same group as the root but is not the root (and thus is not receiving any data). These processes should pass this is as the root for calls to collective communication procedures. Processes in the group sending to the root should use the root process' local rank. The root process should pass in Root.
Root
Indicates that this process is the root for a collective operation. The root process should pass this constant in as the value for root for calls to collective operations. Other processes in the same group as root should use Null. Processes in the group sending to the root should use the root process' local rank.
