The nodes of Origin 200, Origin 2000 and Onyx 2 systems can be
|
|
configured in either N-Modes which allows for more nodes or M-Mode
|
|
which allows for more memory. Your system is most probably
|
|
running in M-Mode, so you should say N here.

Say Y to upport efficient handling of discontiguous physical memory,

for architectures which are either NUMA (Non-Uniform Memory Access)
|
|
or have huge holes in the physical address space for other reasons.

Say Y to compile the kernel to support NUMA (Non-Uniform Memory
|
|
Access). This option is for configuring high-end multiprocessor
|
|
server machines. If in doubt, say N.

Change the way a Linux kernel is loaded into memory on a MIPS64
|
|
machine. This is required in order to support text replication and
|
|
NUMA. If you need to understand it, read the source code.

Say Y here to enable replicating the kernel text across multiple

nodes in a NUMA cluster. This trades memory for speed.
