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.
