Abstract: A method is described that entails operating enabled cores of a multi-core processor such that both cores support respective software routines with a same instruction set, a first core being higher performance and consuming more power than a second core under a same set of applied supply voltage and operating frequency.

Abstract: Some implementations provide techniques and arrangements to migrate threads from a first core of a processor to a second core of the processor. For example, some implementations may identify one or more threads scheduled for execution at a processor. The processor may include a plurality of cores, including a first core having a first characteristic and a second core have a second characteristic that is different than the first characteristic. Execution of the one or more threads by the first core may be initiated. A determination may be made whether to apply a migration policy. In response to determining to apply the migration policy, migration of the one or more threads from the first core to the second core may be initiated.
