Abstract
A first cache simultaneously broadcasts, in a single message, a request for a cache line and a request to accept a future related evicted cache line to multiple other caches. Each of the multiple other caches evaluate their occupancy to derive an occupancy value that reflects their ability to accept the future related evicted cache line. In response to receiving a requested cache line, the first cache evicts the related evicted cache line to the cache with the highest occupancy value.
