Embodiments include an asymmetric multiprocessing (AMP) system having two or more central processing unit (CPU) clusters of a first core type and a CPU cluster of a second core type. Some embodiments include determining a control effort for an active thread group, and assigning the thread group to a first performance island according to the control effort range of the first performance island. The first performance island can include a first CPU cluster of the first core type, where a second performance island includes a second CPU cluster of the first core type, where the second performance island corresponds to a different control effort range than the first performance island. Some embodiments include assigning the first CPU cluster as a preferred CPU cluster of the first thread group, and transmitting a first signal identifying the first CPU cluster as the preferred CPU cluster assigned to the first thread group.
