Comparison of Bucket Sort and RADIX Sort
Bucket sort and RADIX sort are two well-known integer sorting algorithms. This paper measures empirically what is the time usage and memory consumption for different kinds of input sequences. The algorithms are compared both from a theoretical standpoint but also on how well they do in six different use cases using randomized sequences of numbers. The measurements provide data on how good they ...
متن کاملEngineering Radix Sort
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’...
متن کاملA Fast Radix Sort
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...
متن کاملPartitioned Parallel Radix Sort
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 ...
متن کاملConscious Radix Sort
The exploitation of data locality in parallel computers is paramount to reduce the memory traac and communication among processing nodes. We focus on the exploitation of locality by Parallel Radix sort. The original Parallel Radix sort has several communication steps in which one sorting key may have to visit several processing nodes. In response to this, we propose a reorganization of Radix so...
