When a processor group is configured by the node, the memory access performance
becomes high. That is because the logical processor of LPARs , like LPAR1 and LPAR2
below, always uses the local memory in configuration where the processor group and
the physical memory in the same node are assigned to the LPAR.

When making the processor group in a node and allocating the memory in the same
node, the memory accesses are always performed in the local memory and the
memory cost must be smallest.
