A Bitonic Sorter is a parallel sorting algorithm that efficiently sorts a sequence of numbers using a divide-and-conquer approach. It operates by first creating a bitonic sequence, which is a sequence that first increases and then decreases. The algorithm then recursively sorts these sequences, merging them to produce a fully sorted list. This sorting method is particularly well-suited for hardware implementations, such as in Field Programmable Gate Arrays (FPGAs) or Graphics Processing Units (GPUs), due to its predictable pattern of comparisons and swaps. The Bitonic Sorter has a time complexity of O(log² n), making it effective for large datasets in parallel processing environments.
