Abstract
In a computer system having a processor capable of operating at a plurality of performance states, wherein the plurality of performance states includes a low power state and a high performance state and wherein user threads are executable at each of the performance states, a system and method of controlling heat generated by the computer system. A thermal threshold is set. The system enters the high performance state and begins executing user threads. If, while in high performance state, a determination is made that the thermal threshold is exceeded, a transition is made to a low power state.
