should NUMA be enabled in the BIOS of a server that has two sockets but only a single CPU in one of the sockets?
From what I´ve been reading, it is unclear to me if NUMA
should be enabled only on systems with multiple CPUs in multiple sockets or if multiple cores of a single CPU in a single socket benefit from NUMA being enabled, and if memory access in general benefits from NUMA being enabled
(in some other ways) even when there is only a single CPU in a single socket.
It seems clear that NUMA should be enabled an can be taken advantage of when there are multiple CPUs in multiple sockets.
