On POWER8 we have a new concept of a subcore. This is what happens when you take a regular core and split it. A subcore is a grouping of two or four SMT threads, as well as a handfull of SPRs which allows the subcore to appear as if it were a core from the point of view of a guest. Unlike threads_per_core which is fixed at boot, threads_per_subcore can change while the system is running. Most code will not want to use threads_per_subcore.
