Abstract: In a computer system having multiple memory proximity domains including a first memory proximity domain with a first processor and a first memory and a second memory proximity domain with a second processor and a second memory, latencies of memory access from each memory proximity domain to its local memory as well as to memory at other memory proximity domains are probed. When there is no contention, the local latency will be lower than remote latency. If the contention at the local memory proximity domain increases and the local latency becomes large enough, memory pages associated with a process running on the first processor are placed in the second memory proximity domain, so that after the placement, the process is accessing the memory pages from the memory of the second memory proximity domain during execution.
