OMP simd gets ignored in omp loop simd schedule(runtime)

I have made a small testcase out of a bigger program where the compiler fails to vectorize a loop due to "assumed dependency" although one used the loop simd statement:

program fortTest
  integer, allocatable :: vals(:)
  integer, allocatable :: vals2(:)
  integer, allocatable :: send(:)
  integer i,j,ct,tmp,tmp2,tmp3


  ct=10000
  allocate(vals(ct*ct))
  allocate(vals2(ct*ct))
  allocate(send(ct))

  do i=1, ct
    send(i)=i
    do j=1, ct
      vals2(i*ct+j)=i+1+j
    end do
  end do

  !$omp parallel do simd private(tmp,tmp2,tmp3) schedule(runtime)
  do i=1, ct
    tmp = vals2(i) * 2
    tmp2 = vals2(i+ct) * 2
    tmp3 = vals2(i+2*ct) * 2
    vals(send(i)) = tmp+tmp2
    vals(send(i)+i*ct) = tmp+tmp3
  end do

end

Please note, that once u remove the "schedule(runtime)" clause, the loop gets vectorized and my (big) program receives a 4x speedup
