MULTICAST TREE-BASED DATA DISTRIBUTION IN DISTRIBUTED SHARED CACHE |
摘要 |
Systems and methods for multicast tree-based data distribution in a distributed shared cache. An example processing system comprises: a plurality of processing cores, each processing core communicatively coupled to a cache; a tag directory associated with caches of the plurality of processing cores; a shared cache associated with the tag directory; a processing logic configured, responsive to receiving an invalidate request with respect to a certain cache entry, to: allocate, within the shared cache, a shared cache entry corresponding to the certain cache entry; transmit, to at least one of: a tag directory or a processing core that last accessed the certain entry, an update read request with respect to the certain cache entry; and responsive to receiving an update of the certain cache entry, broadcast the update to at least one of: one or more tag directories or one or more processing cores identified by a tag corresponding to the certain cache entry. |

1. A processing system, comprising:
a plurality of processing cores, each processing core communicatively coupled to a cache; a tag directory associated with caches of the plurality of processing cores; a shared cache associated with the tag directory; a processing logic configured, responsive to receiving an invalidate request with respect to a certain cache entry, to:
allocate, within the shared cache, a shared cache entry corresponding to the certain cache entry;transmit, to at least one of: a tag directory or a processing core that last accessed the certain entry, an update read request with respect to the certain cache entry; andresponsive to receiving an update of the certain cache entry, broadcast the update to at least one of: one or more tag directories or one or more processing cores identified by a tag corresponding to the certain cache entry. |
