Removing an item from the middle of a Vector using removeElementAt(n) is achieved by copying all elements from n to the end of the array to the preceding slot. Most of the comments we have made for Vector apply to Stack. There is, however, no Stack constructor that sets its initial size, so you need to use the setSize() method inherited from Vector. A String is frequently used as a key to a Hashtable; however, as we saw in Section 7.8.3, they are not without problems and we suggested that a wrapper class that stores the hash value of the String could provide faster lookup. Integers also make useful keys because Integer.hashCode() simply returns the Integer value. Finally, think about whether an Array might provide a faster and more memory-ef cient container than a Vector or a Hashtable. Vector can be extremely slow if it is used incorrectly. In Wireless Java for Symbian Devices, an example based on a rst-in rst-out queue is given: a vector-based implementation was around 100 times slower than a reasonably optimized array-based implementation.

precedence constraints of G do not permit any earlier termination, independent of the number of involved processors The computation bottom level blw (n) re ects the best-case minimum time until the termination of G s execution, since the costs of communication are neglected, so they must all be local Likewise, a node cannot start earlier than at the time given by its top level tl(n) (once more, assuming that all communications are remote; tlw (n) corresponds to the case that all communications are local) Recall that the top level does not include the cost w(n) of n, while the bottom level does The above observations are formalized in the following lemma Lemma 46 (Level Bounds on Start Time) Let S be a schedule for task graph G = (V, E, w, c) on system P For n V, sl ts (n) + blw (n) ts (n) tlw (n) (434) (435)

where 0 < a < 2. That is, the asymptotic shape of the distribution follows a power law. One of the simplest heavy-tailed distributions is the Pareto distribution. The Pareto distribution is power law over its entire range; its probability density function is given by p x ak a x a 1 ; where a; k > 0, and x ! k. Its distribution function has the form F x P X x 1 k=x a :

The parameter k represents the smallest possible value of the random variable. Heavy-tailed distributions have a number of properties that are qualitatively different from distributions more commonly encountered such as the exponential or normal distribution. If a 2, the distribution has in nite variance; if a 1 then the distribution has also in nite mean. Thus, as a decreases, a large portion of the probability mass is present in the tail of the distribution. In practical terms, a random variable that follows a heavy-tailed distribution can give rise to extremely large le size requests with nonnegligible probability. 14.4.2 Effect of File Size Distribution

First, we demonstrate our central point: the interactive transfer of les whose size distribution is heavy-tailed generates self-similar traf c even when realistic network dynamics, including network resource limitations and the interaction of traf c streams, are taken into account. Figure 14.2 shows graphically that our setup is able to induce self-similar link traf c, the degree of scale-invariant burstiness being determined by the a parameter of the Pareto distribution. The plots show the time series of network traf c measured at the output port of the bottleneck link from the gateway G2 to G1 in Fig. 14.1. This downstream traf c is measured in bytes per unit time, where the aggregation level or time unit varies over ve orders of magnitude from 10 ms, 100 ms, 1 s, 10 s, to 100 s. Only the top three aggregation levels are shown in Fig. 14.2; at the lower aggregation levels traf c patterns for differing a values appear similar to each other. For a close to 2, we observe a smoothing effect as the aggregation level is increased, indicating a
