Until recently, it was not known whether it was possible to stably sort (Le. keeping equal elements in their initial order) an array of n elements using only O(n) data movements and O(1) extra space. In [10], an algorithm was given to perform this task in O(n 2 ) comparisons in...
We present a simple and general parallel sorting scheme, ZZ-sort, which can be used to derive a class of efficient in-place sorting algorithms on realistic parallel machine models. We prove a tight bound for the worst case performance of ZZ-sort. We also demonstrate the average performance of...

ARL is almost twice as fast as Quicksort if N > 100. This applies to the normal case, a uniformly drawn distribution of the numbers 0:N-1. ARL is also in significantly faster than Quicksort for 8 out of 9 other investigated distributions of the numbers to be sorted. ARL is more ...
