A sequence is called Bitonic if it is first increasing, then decreasing. 1 Bitonic sort and sorting network. In other words, an array arr[0. Due to its high modularity, bitonic sort can be mapped to different interconnection networks. Due to this, using adaptive bitonic sort together with other algorithms usually implies converting bitonic trees to arrays and vice versa. Number of comparisons done by Bitonic sort are more compared to other popular sorting algorithms. 1 Location $(AMDAPPSDKSAMPLESROOT)\samples\opencl\cl\app 1. — Addison-Wesley, 1998.
