The algorithmic performance of the suggested parallel algorithm is also compared with the performances of recently reported optimal prefix sum algorithms on [Formula: see text] Biswapped-Mesh and [Formula: see text]-dimensional Biswapped Hyper Hexa-cell. Based on the comparative analysis, Biswapped-...

This is also known as a parallel reduction, because after this phase, the root node (the last node in the array) holds the sum of all nodes in the array. Pseudocode for the reduce phase is given in Algorithm 3.Figure 39-3 An Illustration of the Up-Sweep, or Reduce, Phase of ...
Compute Shader Parallel Prefix Sum A prefix sum operation is an algorithm that, given an array of input values, computes a new array where each element of the output array is the sum of all of the values of the input array up to (and optionally including) the current array element. A ...

We start with a basic naïve algorithm and proceed through more advanced techniques to obtain best performance. We then explain how to scan arrays of arbitrary size that cannot be processed with a single block of threads. This implementation can handle very large arbitrary length vectors thanks ...
