There the procedure mergesort takes a list of length n as input, and returns a sorted list as its output.
-
The recursive calls to mergesort on lists of length n / 2 each take time T (n / 2), hence the term 2T (n / 2).
-
Let T (n) be the worst case running time of the procedure mergesort of Fig. 9.1.
-
For example, in the case of mergesort, where a = b = 2, the first term is n.
-
For example, in the mergesort case, where a = b = 2, and d (n) = cn, we shall see that the particular solution is O (nlogn).
-
There are other methods, such as heapsort and mergesort, that take O (nlogn) time in the worst case, although their average case behavior may not be quite as good as that of quicksort.

a sort. parallelizing a quicksort or mergesort is not really easy, but there are some examples in the GCC libgomp testsuite and it is a very good fit for the OpenMP "#pragma task" directive.
