I'd be suspicious that it is really taking that much time - the routine is rather simple.

In preparation, we have profiled the application to see how it is working under CVF. One specific system routine (_for__desc_ret_item) is taking about 15% of total CPU time. Can you tell us what that routine is, and if that type of usage is reasonable? We don't know if this indicates a problem in the code or not.<BR /><BR />Thanks<BR />Steve Chapman Wed, 21 Dec 2005 03:52:15 GMT https://community.intel.com/t5/Intel-Fortran-Compiler/for-desc-ret-item-for-desc-item-obj/m-p/844649#M62618 schapman 2005-12-21T03:52:15Z https://community.intel.com/t5/Intel-Fortran-Compiler/for-desc-ret-item-for-desc-item-obj/m-p/844650#M62619 This routine is used internally by the run-time library to get the next item in an I/O list.
