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 64-bit this is recommended if the system is Intel Core i7
(or later), AMD Opteron, or EM64T NUMA.
For 32-bit this is only needed if you boot a 32-bit
kernel on a 64-bit NUMA platform.
Otherwise, you should say N.
