What is this NUMA-aware allocation [closed]

It's difficult to tell what is being asked here. Th开发者_JAVA百科is question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I came across NUMA-aware allocation in relation to improving the performance of the application. It is something related to Multicore programming. I know NUMA means non-uniform memory access but I am not aware of NUMA-aware allocation.

Do anyone know about this?

NUMA aware allocation is basically the ability to allocate resources in a way such that the NUMA-properties of the system does not result in unnecessarily long commnication paths. I.e memory should be allocated in the RAM connected directly to the CPU where the process needing it runs, etc
