HUGE PAGES
These can be created by editing sysctl.conf and adding
vm.nr_hugepages=INTEGER
You can also use the following kernel parameter
hugepages=INTEGER
You can check the settings using the following
#cat /proc/meminfo | grep -i huge
HugePages_Total: 20
HugePages_Free: 20
HugePages_Rsvd: 0
Hugepagesize: 4096 kB
If the application uses mmap to request pages then they must be mounted as a filesystem
#mkdir /hugepages
#mount -t hugetlbfs none /hugepages
