**For a simple mathematical example, let us look to the theory of finite fields**

**[E1] [E2] . A finite field is a way of doing arithmetic on a bounded set of integers. For instance, suppose one takes the field of size 13[E3] (the size must be a prime [E4] or a prime raised to some power). Then, in this field the largest number is 12. One has, for example, 12 + 1 = 0, 10 + 5 = 2, 3 x 5 = 2, and 8 x 3 = 12. One can do division in a finite field as well[E5] , although the results are often counter-intuitive -- for instance, 12/8 = 3, and 2/3 = 5 (to see why, just multiply both sides by the denominator).**"

**In finite field theory there is something called the "discrete logarithm" of a number, written dlogb(n). The discrete logarithm is defined just like the ordinary logarithm, as the inverse of exponentiation[E6] . But in a finite field, exponentiation must be defined in terms of the "wrap-around" arithmetic illustrated in the previous paragraph. For instance, in the field of size 7, 3**

*4*= 4. Thus one has dlog3(4) = 4. But how could one compute the log base 3 of 4, without knowing what it was[E7] ? The powers of 3 can wrap around the value 7 again and again -- they could wrap around many times before hitting on the correct value[E8] ,4.

**The problem of finding the discrete logarithm of a number is theoretically easy, in the sense that there are only finitely many possibilities. In our simple example, all one has to do is take 3 to higher and higher powers, until all possibilities are covered. But in practice, if the size of the field is not 7 but some much larger number, this finite number of possibilities can become prohibitively large.**

**So, what if one defines the dynamical system nk = dlogb(nk-1)? Suppose one is given n1, then how can one predict n1000? So far as we know today, there is better way than to proceed in order: first get n2, then n3, then n4, and so on up to n999 and n1000. Working on n3 before one knows n2 is essentially useless, because a slight change in the answer for n2 can totally change the answer for n3[E9] . The only way to do all 1000 steps in parallel[E10] , it seems, would be to first compute a table of all possible powers that one might possibly need to know in the course of calculation. But this would require an immense number of processors; at least the square of the size of the field.**

**This example is, incidentally, of more than academic interest. Many cryptosystems in current use are reliant on discrete logarithms. If one could devise a quick method for computing them, one could crack all manner of codes; and the coding theorists would have to come up with something better.**

**3.4.2. Chaos and Prediction**

**More physicalistic dynamical systems appear to have the same behaviour[E11] . The classic example is the "logistic" iteration xk = cxk-1(1-xk-1), where c[E12] =4 or c assumes certain values between 3.8 and 4[E13] , and the xk are discrete approximations of real numbers. This equation models the dynamics of certain biological populations, and it also approximates the equations of fluid dynamics under certain conditions.**

**It seems very, very likely that there is no way to compute xn from x1 on an ordinary serial computer[E14] , except to proceed one step at a time. Even if one adds a dozen or a thousand or a million processors, the same conclusion seems to hold. Only if one adds a number of processors roughly proportional to 2**

*n*can one obtain a significant advantage from parallelism.

**In general, all systems of equations called chaotic possess similar properties[E15] . These include equations modelling the weather, the flow of blood through the body, the motions of planets in solar systems, and the flow of electricity in the brain. The mathematics of these systems [E16] is still in a phase of rapid development. But the intuitive picture [E17] is clear. To figure out what the weather will be ninety days from now[E18] , one must run an incredibly accurate day-by-day simulation [E19] -- even with highly parallel processing[E20] , there is no viable alternate strategy.**
