摘要:
Embodiments of the invention relate to process identifier (PID) based cache information transfer. An aspect of the invention includes sending, by a first core of a processor, a PID associated with a cache miss in a first local cache of the first core to a second cache of the processor. Another aspect of the invention includes determining that the PID associated with the cache miss is listed in a PID table of the second cache. Yet another aspect of the invention includes based on the PID being listed in the PID table of the second cache, determining a plurality of entries in a cache directory of the second cache that are associated with the PID. Yet another aspect of the invention includes pushing cache information associated with each of the determined plurality of entries in the cache directory from the second cache to the first local cache.
