Pretty sure this is already a thing for NUMA systems, e.g. an Intel system with a pair of N-core processors. Each processor gets "its own" half of memory. Memory which belongs to the other processor is slower to access. See also Linux cpusets (cset command), which can be used to control which NUMA nodes a process has access to.
