Just FYI: the default_hugepagesz part is not necessary, so I'd generally leave it out and let the system default be 2MB as normal. You can always get a hugetlbfs mount of a particular hugepage size by passing the pagesize= parameter when doing the mount.

$cat /proc/meminfo

You may add this parameter in /etc/default/grub
GRUB_CMDLINE_LINUX="default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=512"

Again, please note that after changing the grub defaults you still need to regenerate the grub configuration file, which is generally in /boot (on fedora 20 it's in /boot/grub2/grub.cfg). This is the file actually read at boot time by grub.
