Abstract
A system for dynamically controlling point-of-coherency or a point-of-serialization of shared data includes a plurality of processing engines grouped into a plurality of separate clusters and a shared communications path communicatively connecting each of the plurality of clusters to one another. Each respective cluster includes memory shared by the processing engines of the respective cluster, each unit of data in the memory being assigned to a single owner cluster responsible for maintaining an authoritative copy and a single manager cluster permanently responsible for assigning the owner cluster responsibility. Each respective cluster also includes a controller configured to receive data requests, track each of a manager status and an ownership status of the respective cluster, and control ownership status changes with respect to respective units of data based at least in part on the tracked ownership and manager statuses of the respective cluster.
