More on HugeMem@Linux 32 bit

In a hugemem kernel system in “/etc/sysctl.conf” you will see this entry:

# hygepages setting

vm.nr_hugepages=20480

 

File:/proc/sys/vm/nr_hugepages

 

[root@siebelapp1 ~]# cat /proc/sys/vm/nr_hugepages
20480

echo 2048 > /proc/sys/vm/nr_hugepages
A page, by dafeult, is 2MB so with 2048 you are allocating 4GB of your RAM for hugepages.
