This does not change the timing for test_fpu.f90 and the reduced test in
comment #1.

AFAICT the problem is within the loop

   DO j = 1, n
      c = b(k,j)*d
      do i = 1, n
         b(i,j) = b(i,j)-temp(i)*c
      end do
      b(k,j) = c
   END DO

(where it does not matter that

       b(:,j) = b(:,j)-temp*c

is scalarized or not).
