Managing thread affinity on multi-core processors

A method comprising:

• identifying one or more resources associated with each of a plurality of core processors on a multi-core processor;
• receiving a request to execute an instruction associated with a thread, said instruction corresponding to at least one of the identified resources;
• selecting one of the plurality of core processors based on the corresponding resource;
• and
• assigning the thread to the selected one of the plurality of core processors, wherein the selected one of the plurality of core processors executes the instruction and subsequent instructions from the assigned thread responsive to said assigning the thread.

One or more computer-readable media storing computer-executable components, said components comprising:

• an affinity component for accessing a defined relationship between each of a plurality of threads and a plurality of core processors on a multi-core processor, wherein the plurality of core processors executes instructions from the plurality of threads based on the defined relationship;
• a threshold component for defining an activity limit for each relationship accessed by the affinity component;
• a performance component for monitoring usage of the plurality of core processors by the plurality of threads;
• and
• a maintenance component for comparing the usage monitored by the performance component to the activity limit for each relationship defined by the threshold component, said maintenance component further terminating the relationship for one or more of the threads based on said comparing, wherein any of the plurality of core processors executes subsequent instructions from said one or more of the threads responsive to said terminating.
