WebJun 25, 2024 · I have an array of structs containing two unsigned integers. I want to sort these according to the first uint using Bitonic Sorting. I implemented this code here which was in directX (I converted it to glsl). everything works however performance is suffering. CPU sorting does this 10 times faster (using std::sort), am I missing something?? WebBlock sort, or block merge sort, is a sorting algorithm combining at least two merge operations with an insertion sort to arrive at O(n log n) in-place stable sorting. It gets its name from the observation that merging two sorted lists, A and B, is equivalent to breaking A into evenly sized blocks, inserting each A block into B under special rules, and merging …

"WebDec 31, 2024 · What is the Bitonic sort? It is a sorting algorithm that runs parallel. In this algorithm, there are O(n2 log n) comparisons. Although the number of comparisons is more, it’s more suitable for parallel implementation because the elements are compared in a predefined sequence (the bitonic sequence) that doesn’t depend on data.
