Abstract
A method of caching data in a multi-processor computing environment, involves the steps of receiving from one of a plurality of network clients a request for a data item; establishing a private cache uniquely associating with the network client; associating the private cache with a shared cache, the shared cache including the requested data item and being associated with a number of the network clients; and updating the private cache with the requested data item. In one aspect, the shared cache includes a subset of a store of dynamically-variable data, and the method also involves storing in the shared cache a data update received from one of the network clients; receiving from another of the network clients a request for an item of the variable data; and updating the private cache of the one network client with the update data and the requested data item.
