• allocate, for the application logic, a region of external primary memory included in a memory appliance;
• select, in response to a first request to reclaim a first portion of local primary memory in the client device, a portion of external primary memory from the region of external primary memory;
• copy data from the first portion of local primary memory to the portion of external primary memory;
• and
• convert a portion of a first virtual address space at the client device by remapping at least one virtual address in the first virtual address space at the client device from the first portion of local primary memory to the portion of external primary memory.

A non-transitory storage medium for storing computer readable instructions, the computer readable instructions, when executed by a processor of a client device, causing the processor to:

• allocate, for an application logic, a region of external primary memory included in a memory appliance;
• select, in response to a first request to reclaim a first portion of local primary memory in the client device, a portion of external primary memory from the region of external primary memory;
• copy data from the first portion of local primary memory to the portion of external primary memory;
• and
• convert a portion of a first virtual address space at the client device by remapping at least one virtual address in the first virtual address space at the client device from the first portion of local primary memory to the portion of external primary memory.
