Abstract
An aspect includes receiving a request to access data in a memory, the request from a requesting processor and including a virtual address of the data. It is determined, based on contents of a page table that a plurality of physical addresses in the memory corresponds to the virtual address. The physical addresses include a first physical address of a primary memory location in a first partition accessed via a bus that is communicatively coupled to a port of a first processor, and a second physical address of a secondary memory location in a second partition accessed via a bus that is communicatively coupled to a port of a second processor. Contents of the primary memory location in the first partition were previously copied into the secondary memory location. Based on the requesting processor, one of the physical addresses is selected and data at the selected physical address is accessed.

17. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:
-
receiving a request to access data in a partitioned memory, the request from a requesting processor and including a virtual address of the data; determining, based at least in part on contents of a page table, that a plurality of physical addresses in the memory correspond to the virtual address, the physical addresses comprising; a first physical address of a primary memory location in a first partition accessed via a first memory bus communicatively coupled to a port of a first processor; and a second physical address of a secondary memory location in a second partition accessed via a second memory bus communicatively coupled to a port of a second processor, wherein contents of the primary memory location in the first partition were previously copied into the secondary memory location in the second partition; selecting, based at least in part on the requesting processor, one of the physical addresses; and accessing the data at the selected physical address. - View Dependent Claims (18, 19, 20)
