METHOD, COMPUTER PROGRAM, AND MEMORY ACCESS MANAGEMENT DEVICE IN NUMA TYPE MULTIPROCESSOR ARCHITECTURE

摘要

The object of the invention is in particular to manage memory accesses in a multiprocessor architecture of the NUMA type comprising at least two calculation units and at least two distinct memories, each memory comprising at least one memory logical entity, being associated locally with a memory device. computing unit. After receiving an access command for a memory logical entity, the status of a status indicator of said memory logical entity, referred to as the first entity, targeted by said received command, is determined (215). If said flag is in a first state, said received command is executed (220). If, on the contrary, said indicator is in a second state, data stored in said first entity is migrated (225) in a memory logical entity, called second entity, of a memory separate from the memory comprising said first entity and the the status of said second entity is set to the first state (230).
