We saw that our measurements of the prefix-sum function psum 1 (Figure 5.1) yield a CPE of 9.00 on a machine where the basic operation to be performed, floatingpoint addition, has a latency of just 3 clock cycles. Let us try to, , 4 derstand why our function performs so poorly. The following is the assembly code for the inner loop of the function: | Numerade
