Skip lists are also useful in parallel computing, where insertions can be done in different parts of the skip list in parallel without any global rebalancing of the data structure. Such parallelism can be especially advantageous for resource discovery in an ad-hoc wireless network because a randomized skip list can be made robust to the loss of ...

A skip graph is a distributed data structure based on skip lists designed to resemble a balanced search tree.They are one of several methods to implement a distributed hash table, which are used to locate resources stored in different locations across a network, given the name (or key) of the resource.
In a skip list, one can finger search for x from a node containing the element y by simply continuing the search from this point. Note that if x < y, then search proceeds backwards, and if x > y, then search proceeds forwards. The backwards case is symmetric to normal search in a skip list, but the forward case is actually more complex.
The simplest, most general, and least efficient search structure is merely an unordered sequential list of all the items. Locating the desired item in such a list, by the linear search method, inevitably requires a number of operations proportional to the number n of items, in the worst case as well as in the average case. Useful search data ...
I've actually tested skip lists extensively and can tell you that in C++ at least, skip lists are exactly on par and occasionally faster with the map template for speed and use about the same amount of memory. Skip lists memory usage and speed can be tweaked according to your need and can reproduce a map quite easily.
William Worthington Pugh Jr. (born 1960) is an American computer scientist who invented the skip list and the Omega test for deciding Presburger arithmetic.He was the co-author of the static code analysis tool FindBugs, and was highly influential in the development of the current memory model of the Java language.
