摘要:
Methods and systems for cache management are provided. Aspects include providing a drawer including a plurality of clusters, each of the plurality of clusters including a plurality of processor each having one or more cores, wherein each of the one or more cores shares a first cache memory, providing a second cache memory shared among the plurality of clusters, and receiving a cache line request from one of the one or more cores to the first cache memory, wherein the first cache memory sends a request to a memory controller to retrieve the cache line from a memory, store the cache line in the first cache memory, create a directory state associated with the cache line, and provide the directory state to the second cache memory to create a directory entry for the cache line.
