Abstract
A distributed data processing system includes: (1) a first node with a processor, a first memory, and asynchronous memory mover logic; and connection mechanism that connects (2) a second node having a second memory. The processor includes processing logic for completing a cross-node asynchronous memory move (AMM) operation, wherein the processor performs a move of data in virtual address space from a first effective address to a second effective address, and the asynchronous memory mover logic completes a physical move of the data from a first memory location in the first memory having a first real address to a second memory location in the second memory having a second real address. The data is transmitted via the connection mechanism connecting the two nodes independent of the processor.
