Thank you very much.
I still have a question. How can I know that have been take effect?
I take steps as follow:
------------------
mkdir /hugetlb
mount -t hugetlbfs hugetlbfs /hugetlb
HUGETLB_MORECORE=yes LD_PRELOAD=libhugetlbfs.so hugepagesz=16M hugepages=32
./myprogram
------------------
That's right?

You can *only* do this by adding "hugepagesz=16M hugepages=32" into

to preallocate 32 16M hugepages.
Prerequisite is you hardware support 16M huge page.
