Recommended example of LPAR configuration reducing the memory access
cost
When the memory access performance is very important, you should assign the
processor and memory to LPAR so that they might be configured in one node.
Please note the following points.
The memory access cost can be reduced only when the memory amount of LPAR

is not more than the one in single node.
Basically, it is unnecessary to specify a memory node. (Use the automatic

memory assignment.)
However, when you need to suppress the activation if there is not enough free

memory in the node, specify the memory node.
Specify the memory node to all LPARs when you make at least one LPAR which

specifies the memory node.
Do not intermingle the LPAR which specifies the memory node and the LPAR

which does not specify the memory node.
