Memory page offloading in multi-node computer systems

摘要

Systems and methods for memory page offloading in multi-processor computer systems. An example method may comprise: detecting, by a computer system, a memory pressure condition on a first node; invalidating a page table entry for a memory page residing on the first node; copying the memory page to a second node; and updating the page table entry for the memory page to reference the second node.

1. A method, comprising:
detecting, by a processor, a memory pressure condition on a first node; invalidating a page table entry for a memory page residing on the first node; copying, by the processor, the memory page directly to a second node without swapping the memory page to a backing storage; and updating the page table entry for the memory page to reference the second node.
