             Bug #: 55691
           Summary: Setting OMP_NESTED increases the runtime dramatically
                    for GCC compiled executable
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgomp
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: geir@cray.com
                CC: jakub@gcc.gnu.org


The attached test case runs significantly slower when setting OMP_NESTED =
true, compared to setting OMP_NESTED.
