The glossary defines "compute nodes".

What does hosting Compute mean? Parts of Compute are deployed on the
controller nodes, and nova-compute runs on the compute nodes.

My reference is:
http://docs.openstack.org/trunk/install-guide/install/zypper/content/ch_overview.html#overview-architecture

If you have a node where the compute service is hosted, it's the
controller node.

So, IMHO we should use "compute node" (lower case!) and "compute host"
if you speak about the node where virtual machines run on. If you speak
about the machine that hosts Compute Services, it's the "controller
node". In both cases we use lower case,
