Technologies are described herein generally relate to aggregation of cache eviction notifications to a directory. Some example technologies may be utilized to update an aggregation table to reflect evictions of a plurality of blocks from a plurality of block addresses of at least one cache memory. An aggregate message can be generated, where the message specifies the evictions of the plurality of blocks as reflected in the aggregation table. The aggregate message can be sent to the directory. The directory can parse the aggregate message and update a plurality of directory entries to reflect the evictions from the cache memory as specified in the aggregate message.
