# psort, Yet Another Fast Stable Sorting Software

@inproceedings{Bertasi2009psortYA, title={psort, Yet Another Fast Stable Sorting Software}, author={Paolo Bertasi and Marco Bressan and Enoch Peserico}, booktitle={SEA}, year={2009} }

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 .

Of the many implementation and configuration choices the authors faced, the most crucial were judicious data placement and access patterns on disk, adoption of UDP sockets instead of MPI, careful pruning of virtually all system daemons, and rejection of ``on demand'' frequency scaling.

Parallel sorting on a shared-nothing architecture using probabilistic splitting

- Computer Science[1991] Proceedings of the First International Conference on Parallel and Distributed Information Systems
- 1991

The authors consider the problem of external sorting in a shared-nothing multiprocessor with two techniques for determining ranges of sort keys: exact splitting, using a parallel version of the algorithm proposed by Iyer, Ricard, and Varman; and probabilistic splitting, which uses sampling to estimate quantiles.
