Abstract
Systems, apparatuses and methods may provide for detecting an issued request in a queue that is shared by a plurality of domains in a memory architecture, wherein the plurality of domains are associated with non-uniform access latencies. Additionally, a destination domain associated with the issued request may be determined. Moreover, a first set of additional requests may be prevented from being issued to the queue if the issued request satisfies an overrepresentation condition with respect to the destination domain and the first set of additional requests are associated with the destination domain. In one example, a second set of additional requests are permitted to be issued to the queue while the first set of additional requests are prevented from being issued to the queue, wherein the second set of additional requests are associated with one or more remaining domains in the plurality of domains.
