Independent Example 1

This is independent,

    !HPF$ INDEPENDENT
    DO i = 1, n
     b(i) = b(i) + b(i)
    END DO

this is not, (dependence on order of execution),

    DO i = 1, n
     b(i) = b(i+1) + b(i)
    END DO

nor is this,

    DO i = 1, n
     b(i) = b(i-1) + b(i)
    END DO

however, this is

!HPF$ INDEPENDENT
    DO i = 1, n
     a(i) = b(i-1) + b(i)
    END DO
