separate nodes::
For 1G pages, it is not possible to reserve the hugepage memory after the
system has booted.
+ On IBM POWER system, the nr_overcommit_hugepages should be set to the same
value as nr_hugepages.
+ For example, if the required page number is 128, the following commands
are used::
+
+ echo 128 > /sys/kernel/mm/hugepages/hugepages-16384kB/nr_hugepages
