A method and system for monitoring assets using radio frequency tags is provided that includes a plurality of primary tags. Each primary tag stores an identification of each linked tag associated with the primary tag. The primary tag receives a polling event and transmits a query message for linked tags within an operational range of the primary tag.

A processor (100) in a distributed shared memory computer system (10) receives ownership of data and initiates an initial update to memory request. A front side bus processor interface (24) forwards the initial update to memory request to a memory directory interface unit (22). The front side processor interface (24) may receive subsequent update to memory requests for the data from processors co-located on the same local bus. Front side bus processor interface (24) maintains a most recent subsequent update to memory in a queue (102). Once the data has been updated in its home memory (17), the memory directory interface unit (22) sends a writeback acknowledge to the front side bus processor interface (24). The most recent subsequent update to memory request in the queue (102) is then forwarded by the front side bus processor interface (24) to the memory directory interface unit (24) for processing.
