Abstract
psort was the fastest sorting software in 2008 according to the Pennysort benchmark, sorting 181GB of data for 0.01$ of computer time. This paper details its internals, and the careful fitting of its architecture to the structure of modern PCs-class platforms, allowing it to outperform state-of-the-art sorting software such as GNUsort or STXXL.
