Q. Show Independent loops in fortran program?

In the subsequent code portion the directives point to the outer two loops are independent. The inner loop allocates elements of A frequently and therefore it is not independent.

!HPF$ INDEPENDENT

do i=1,n1 ! Loop over i independent

!HPF$ INDEPENDENT

do j=1,n2 ! Loop over j independent

do k=1,n3 ! Inner loop not independent

A(i,j) = A(i,j) + B(i,j,k)*C(i,j)

enddo
