As using argument is too much code change and also mmap with hugepage support not available in all platform, so, I decide to use compiler option to switch on this feature. i.e. cmake .. -DGGML_USING_HUGE_PAGE_1G=1
The hugepage feature requires model file must exist in hugetlbfs, and also Linux kernel command to boot with designate hugepagesz to be set. Also "copy" normal model file to hugetlbfs mount point requires also using a small tool with mmap. Therefore this is considered to be an advanced feature.
