Thanks

By default CPLEX uses as many threads as there are cores.

If you want to use more threads than you have processors, then you have to explicitly set CPX_PARAM_THREADS. Notice however that using more threads than cores frequently results in a performance degradation, so carefully double-check whether this is helpful at all.
