# GAP Message (Diagnostic ID 30525)

### Note

This feature is only available for ifort.

## Message

Insert a "%s loop count min(%d)" statement right before the loop at line %d to parallelize the loop.

## Advice

Add "!DIR$ LOOP COUNT" before the specified loop. This directive indicates the minimum trip count (number of iterations) of the loop that enables the parallelization of the loop.

## Example

Consider the following:

          subroutine foo (n)
          integer, parameter :: N2 = 10000
          real (8) :: A(N2), B(N2)
          integer :: i, n
          do i =1, n
             A(i) = B(i) * B(i)
          end do
          end subroutine foo

In this case, if the trip count of the loop at line 5 is greater than 128, then use the LOOP COUNT directive to parallelize this loop.

If you determine it is safe to do so, you can add the directive as follows:

          subroutine foo (n)
          integer, parameter :: N2 = 10000
          real (8) :: A(N2), B(N2)
          integer :: i, n
          !dir$ loop count min(128)
          do i =1, n
             A(i) = B(i) * B(i)
          end do
          end subroutine foo

Make sure that the loop has a minimum of 128 iterations.

## Verify

Confirm that the loop has the minimum number of iterations, as specified in the diagnostic message.
