A method includes, in a computing system that includes one or more compute nodes that run clients, defining memory chunks, each memory chunk including multiple memory pages accessed by a respective client. Respective similarity-preserving signatures are computed for one or more of the memory chunks. Based on the similarity-preserving signatures, an identification is made that first and second memory chunks differ in content in no more than a predefined number of memory pages with at least a predefined likelihood. Efficiency of access to the identified first and second memory chunks is improved.

Cluster-wide memory management using similarity-preserving signatures

A method includes running a Virtual Machine (VM) on a first compute node in a plurality of compute nodes that communicate with one another over a communication network. The VM is migrated from the first compute node to a second compute node in the plurality by generating, for memory pages accessed by the VM, page transfer state of one or more local memory pages that are accessed locally on the first compute node, and of one or more externalized memory pages whose access is not confined to the first node. Based on the page transfer state, the migrated VM is provided with access to the memory pages, including both the local and the externalized memory pages, on the second compute node.
