└─>Processor type and features
└─>Numa Memory Allocation and Scheduler Support (EXPERIMENTAL)
In linux kernel since version 2.6.12
Enable NUMA (Non Uniform Memory Access) support.
The kernel will try to allocate memory used by a CPU on the
local memory controller of the CPU and add some more
NUMA awareness to the kernel.
For i386 this is currently highly experimental and should be only
used for kernel development. It might also cause boot failures.
For x86_64 this is recommended on all multiprocessor Opteron systems.
If the system is EM64T, you should say N unless your system is
EM64T NUMA.
