Abstract
In a multiprocessor computing system, virtual memory addresses are mapped to local physical memory addresses of an attraction memory, containing a replication of the data contained at remote physical addresses, in a node of the system. A mapping table is created and maintained in each node of the system to supplement a conventional page table. The mapping table is used to map a global physical address to a local physical address of the replicated page of memory. System performance is enhanced by subsequent access to the data stored at the local physical address, as opposed to the remote physical address.
