Parallel External Memory Wavelet Tree and Wavelet Matrix Construction
Abstract
We present the first parallel external memory wavelet tree and matrix construction algorithm. The algorithm’s throughput is nearly the same as the hard disk drives’ throughput, using six cores. We also present the fastest (parallel) semi-external construction algorithms for both wavelet trees and matrices.
