Radix sorting methods have excellent asymptotic performance on string data, for which comparison is not a unit-time operation. Attractive for use in large byteaddressable memories, these methods have nevertheless long been eclipsed by more easily programmed algorithms. Three ways to sort strings by bytes left to right—a stable list sort, a stable two-array sort, and an in-place ‘‘American flag’...

An algorithm is a well-defined procedure that takes some input in the form of some values, processes them and gives the desired output. It forms the basis of many other algorithms such as searching, pattern matching, digital filters etc., and other applications have been found in database systems, data statistics and processing, data communications and pattern matching. This paper introduces al...

NTsort is an external sort on WindowsNT 5.0. It has minimal functionality but excellent price performance. In particular, running on mail-order hardware it can sort 1.5 GB for a penny. NT5.0 is not yet available. For commercially available sorts, Postman Sort from Robert Ramey Software Development has elapsed time performance comparable to NTsort, while using less processor time. It can sort 1....

Almost all computers regularly sort data. Many different sort algorithms have therefore been proposed, and the properties of these algorithms studied in great detail. It is known that no sort algorithm based on key comparisons can sort N keys in less than O(N\og/V) operations, and that many perform 0(N) operations in the worst case. The radix sort has the attractive feature that it can sort N k...

Load balanced parallel radix sort solved the load imbalance problem present in parallel radix sort. By redistributing the keys in each round of radix, each processor has exactly the same number of keys, thereby reducing the overall sorting time. Load balanced radix sort is currently known as the fastest internal sorting method for distributed-memory multiprocessors. However, as the computation ...
