SYSTEMS AND METHODS FOR MANAGING LARGE CACHE SERVICES IN A MULTI-CORE SYSTEM

摘要

A multi-core system that includes a 64-bit cache storage and a 32-bit memory storage that stores a 32-bit cache object directory. One or more cache engines execute on cores of the multi-core system to retrieve objects from the 64-bit cache, create cache directory objects and insert them into the cache object directory, and search for cache directory objects in the cache object directory. When an object is stored in the 64-bit cache, a cache engine can create a cache directory object that corresponds to the cached object, and can insert the created cache directory object into an instance of a cache object directory of that cache engine. A second cache engine can receive a request to access the cached object and can identify a cache directory object in the instance of the cache object directory, using a hash key calculated based on one or more attributes of the cached object.
