ABSTRACT:
A command from an application is received to access a data structure associated with one or more virtual addresses mapped to main memory. A first subset of the virtual addresses for the data structure having constituent addresses that are mapped to the symmetric memory components and a second subset of the virtual addresses for the data structure having constituent addresses that are mapped to the asymmetric memory components are identified. Data associated with the virtual address from the first physical addresses and data associated with the virtual addresses from the second physical addresses are accessed. The data associated with the symmetric and asymmetric memory components is accessed by the application without providing the application with an indication of whether the data is accessed within the symmetric memory component or the asymmetric memory component.
