You're right, the term "Compute Node" by itself has no connection
to the topological properties of the fat tree. However, fat-tree
routing has some constraints on the topology, and one of these
constraints is that all the compute nodes are required to be
located at the same topological level of the tree (same rank).
Which again means that the definition of compute nodes is only
necessary for the ability to balance these separately in the tree?
Right again, this is what the fat-tree routing does.

Thanks for your answer,

Hi Frank,
A compute node is a computer/server that is generally dedicated to
doing computational work in a cluster or group of computers.

Hi,
I have been looking into the fat tree code, and I was wondering about
the definition of a compute node (CN). Are these part of the leaf
switches at the bottom of the fat tree, or are they extra switches
that are connected to the fat tree, e.g. the switch in a rack of
blades which is again connected to the fat tree?
Appreciate the help,
