METHOD, DEVICE AND COMPUTER PROGRAM FOR DYNAMIC MONITORING OF MEMORY ACCESS DISTANCES IN A NUMA TYPE SYSTEM

摘要

The dynamic monitoring of distances, in particular of memory access distances, in a non-uniform memory access (NUMA) type system comprising a plurality of processors, and a local memory being associated with each processor of the plurality of processors is disclosed. In one aspect, after having obtained at least one NUMA distance between at least one first processor of the plurality of processors and a local memory associated with at least one second processor of the plurality of processors, the at least one NUMA distance obtained is stored in place of at least one NUMA distance, previously stored, between the at least one first processor and the local memory associated with the at least one second processor, the at least one NUMA distance stored being usable directly by the operating system of the NUMA type system.
