How to utilize huge pages with icc/ifort

I am trying to use huge pages with the icc/ifort linux compiler.  In open64 there's a compilation flag for this as well as an enviroment variable I can set to limit how many pages each process uses.  How does one use huge pages in Intel compilers?  Is the stratety to rely upon the Red Hat annonymous huge pages.. and let the OS do it?  Can someone explain.. many thanks..

Normally, the Red Hat 6 transparent huge pages feature is used automatically.

A better explanation is supposed to be posted at

http://int-software.intel.com/en-us/articles/large-page-considerations

but I can't reach this page.  I guess it should move to software.intel.com some day.

Huge Pages support in any OSs should bbe transparent for any applications, including C++ compilers.
