Parallel sorting is an interesting topic in its own right, but the bottom line is that we can use parallel radix sort to yield a linear execution time with respect to the number of objects (given that there is enough work to fill the GPU). In the third step, we launch one thread per...
Sorting is one of the most fundamental problems in software algorithms; there are many sequential sorting algorithms with different time and memory complexities, but when it comes to parallel sort, things get more complicated. I will explain a simple and scalable algorithm to write a parallel sort...
The experiment compares the different parallel sorting algorithms provided in the sample pack based on different parameters that may affect the performance of the algorithm such as:1) Number of elements to compare - this directly affects work-granularity and the median used by some sorts. For ...
