Thermal capacity optimization for maximized single core performance

Abstract:

Embodiments of the present invention disclose a method, computer program product, and system for processing a thread of execution on a plurality of independent processing cores. In various embodiments, a run state and a local maximum thermal power is assigned to each of at least part of the cores. A first one of the cores is set to the active state. The thread on the first core in the active state is processed. The processing of the thread on the first core for fulfilment of an interrupt condition is monitored. A second one of the cores is set to the active state. The processing of the thread on the first core is halted. The processing of the thread to the second core is transferred. The processing of the thread on the second core in the active state continues and the first core is set to the cooling state.
