Licensing cores vs. threads within zones on T series sparc servers

 The section below is from a document about how to deploy oracle databases on T series machines.   I'm currently trying to nail down (for licensing purposes) exactly what the ncpus variable is defining.  Is it 1 core=1 cpu or is it 0-7 HW threads on a given core?   I'm finding information separately about the separate issues but nothing that distinguishes oracles view of a zone resource applied to a license requirement.

Dedicated CPU

With the introduction of the dedicated CPU feature, system administrators now have a much easier and also more effective way of managing pools of CPUs. In reality, system administrators do not even have to care about creating CPU pools. Of course, they must know how many CPUs are available and how they are used. With the dedicated CPU feature, administrators can assign CPUs right when they are creating a new zone and they can manage assigned CPUs by changing zone properties.
