Abstract
In one embodiment of multi-mode task dispatching for extreme temperature avoidance, a performance-based dispatching mode includes a heating sub-mode in which heat generating non-system workload tasks are dispatched to idle processor cores of a set of available processor cores to raise the temperature of processing cores receiving a heat generating task. The heating sub-mode is entered if a multi-processor core temperature such as the ambient temperature of a CPU complex, for example, is below a sub-mode temperature threshold value. In this manner, the ambient temperature of the CPU complex may be prevented from reaching or maintaining a level which causes the CPU complex to fully or partially shut down due to low temperatures. Other features and aspects may be realized, depending upon the particular application.
