Please correct me if it is not the case.
By "non-transparent" do you mean explicit huge pages API which allows them to be allocated on-demand rather than heuristically, such as was implemented in Linux for at least 8 years (http://goo.gl/8qZX4D, https://lwn.net/Articles/375096/) and supported by major software products (http://goo.gl/prxjjo, http://goo.gl/fQOLwO, http://goo.gl/pr7Tbb, http://goo.gl/Y9qtWk, http://goo.gl/M0l7LL, etc.)? I haven't heard about it (but I hope I'm wrong :) ).
