Using these results we then show that the average running times of odd-even merge sort and bitonic merge sort are O((n/p) (log n + (log(1 +p 2 /n)) 2 )), that is, the two algorithms are optimal on the average if \\(n \\geqslant p^2 /2^{\\sqrt {\\log p} }\\) ....
Bitonic Sort 第一步:建立一个高效的网络对bitonic序列进行排序 大概的概念:将序列分成两半,一半是bitonic并且已经排序(干净),另一半只是bitonic。 提醒:我们只处理二进制序列(元素为 0 或 1) 可以证明对所有二进制序列都正确的排序网络也适用于一般输入序列 第二步:建立一个高效的网络来对一般(二进制)序列进行排序...
After sorting the chunks, we use a parallel bitonic merge to combine pairs of chunks into one. This merge is repeated until a single sorted array is produced.Step 1: Radix Sort ChunksRadix sort is particularly well suited for small sort keys, such as small integers, that can be expressed ...
voidbitonic_sort(T*items,intlo,intn,booldir) {if(n >1) {// Divide the array into two partitions and then sort// the partitions in different directions.intm = n /2; bitonic_sort(items, lo, m, INCREASING); bitonic_sort(items, lo + m, m, DECREASING);// Merge the results...
parallel_bitonic_merge(items, lo, n, dir); } } To reduce overhead, the parallel_invoke algorithm performs the last of the series of tasks on the calling context. For the complete version of this example, see How to: Use parallel_invoke to Write a Parallel Sort Routine. For more infor...

We adapt the well known and well studied parallel sort-merge and bitonic-sort algorithms for declustered data and compare analytically their performance. We show that the adapted bitonic sort outperforms the adapted sort-merge algorithm for declustered data in resemblance to the results of their ...
Sort all the elements I've prototyped radix sort and bitonic sort for this, but this brings its own issues We're doing more work than necessary since we only care about 1024 out of the 8,388,608, most of the sorting is useless
This file implements a bitonic sorter with immutable tree rotations. It is not the kind of algorithm you'd expect to run fast on GPUs. Yet, since it uses a divide-and-conquer approach, which is inherently parallel, Bend will run it multi-threaded. Some benchmarks:...
Then, the process for bitonic sort is given in Figure 11. Without going into details, the main point in the typing of those relations is to find a solution to a recurrence relation for the complexity of server types. In the typing of bmerge, we suppose given a list of size smaller ...
