... the asymptote is the inverse of the serial portion of the code, which controls the scalability of the application
. In this example, p
= 0.8 and (1 – p
) = 0.2, so the asymptotic value is a

Notice that the denominator is now a function of n

From Equation 8 you can plot the speedup. As with the previous problem, assume a parallel portion p
= 0.8, leaving a
serial portion s

When the number of cycles is known at compile time, a loop can be fully unrolled:
c[0] = a[0] + b[0];
c[1] = a[1] + b[1];
c[2] = a[2] + b[2];
c[3] = a[3] + b[3];
However, it remains
