Detailed Description

A node-aware strategy that sends along a node-based tree with user specified branching factor.

Once the message reaches the PE representative for each node, it is forwarded from the PE to all other destination PEs on the node. This strategy can result in imbalanced loads. The PEs along the tree have higher load than the other PEs.
