Abstract
An apparatus and method for intelligently scheduling threads across a plurality of logical processors. For example, one embodiment of a processor comprises: a plurality of logical processors including comprising one or more of a first logical processor type and a second logical processor type, the first logical processor type associated with a first core type and the second logical processor type associated with a second core type; a scheduler to schedule a plurality of threads for execution on the plurality of logical processors in accordance with performance data associated with the plurality of threads; wherein if the performance data indicates that a new thread should be executed on a logical processor of the first logical processor type, but all logical processors of the first logical processor type are busy, the scheduler to determine whether to migrate a second thread from the logical processors of the first logical processor type to a logical processor of the second logical processor type based on an evaluation of first and second performance values associated with execution of the first thread on the first or second logical processor types, respectively, and further based …
