The correct usage of the hugepagesz and hugepages options are on the kernel command line, not at program execution. That said this option will only work where there is hardware support for 16MB pages and neither Intel, nor AMD support this huge page size. I am assuming you are running x86_64 because of your default huge page size of 2M. If so, these options will not work for you.
