Abstract: Methods, systems, and computer program products for high-performance multi-node computing. Upon receiving a request to move a computing process from a first computing node to a second computing node, an agent responds to the request by: copying contents of one or more pages of the computing process from the first computing node to the second computing node, identifying page recency metadata corresponding to the one or more pages of the computing process, and copying all or portions of the identified page recency metadata to the second computing node. When the CPU of the second computing node accesses pages of the moved computing process, the operating system of the second computing node observes page recency metadata that had been copied from the first node and stored at the second computing node. The computing process might comprise a virtual machine, a guest operating system, or an executable container.

Abstract: In some aspects, a non-transitory computer readable storage medium includes instructions stored thereon that, when executed by a processor, cause the processor to create a virtual swap space that is exposed to a core system software, intercept a first page selected by the core system software to be swapped out to the virtual swap space, map the virtual swap space to a physical swap space that is allocated to a type of page associated with first swap metadata, and write the first page to the physical swap space based on the first page having the first swap metadata. In some embodiments, the first page is associated with the first swap metadata.
