MEMORY MIGRATION WITHIN A MULTI-HOST DATA PROCESSING ENVIRONMENT

A destination host includes a processor core, a system fabric, a memory system, and a link controller communicatively coupled to the system fabric and configured to be communicatively coupled, via a communication link, to a source host with which the destination host is non-coherent. The destination host migrates, via the communication link, a state of a logical partition from the source host to the destination host and page table entries for translating addresses of a dataset of the logical partition from the source host to the destination host. After migrating the state and page table entries, the destination host initiates execution of the logical partition on the processor core while at least a portion of the dataset of the logical partition resides in the memory system of the source host and migrates, via the communication link, the dataset of the logical partition to the memory system of the destination host.
