  9           The nodes of Origin, Onyx, Fuel and Tezro systems can be configured
 10           in either N-Modes which allows for more nodes or M-Mode which allows
 11           for more memory.  Your hardware is almost certainly running in
 12           M-Mode, so choose M-mode here.

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

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