Abstract
Managing cache memories in a computing system comprising multiple cores includes: assigning home cache locations for portions of data stored among caches in a group of caches of respective cores; accessing a first one of the portions of the cached data by sending an access request to a first home core of that first one of the portions of cached data; tracking a history of access for the first one of the portions of cached data; determining whether the tracked history of access for the first one of the portions of cached data exceeds or meets a predetermined condition, and re-assigning a home cache location of the first one of the portions of cached data from the first home core to a second, different home core when the predetermined condition is met or exceeded.
