Abstract
A server is provided with operating logic that dynamically migrates or shadows data it shares with its client, in accordance with a migration/shadowing policy that is based on one or more migration/shadowing heuristics. The server is also provided with operating logic that creates the shared data in accordance with a creation policy that is based on one or more creation heuristics. Furthermore, the server is provided with operating logic that maintains the migration/shadowing as well as the creation heuristics in accordance with an update policy. In one embodiment where the data are pixel maps, the migration/shadowing and creation heuristics are corresponding local usage counts, one per pixel map, and a global usage count respectively. The usage counts are incremented and decremented depending on the destinations of the pixel maps of interest.
