* @brief Implementation of a dynamically load-balanced parallel quicksort.
*
* It works in-place and needs only logarithmic extra memory.
+ * The algorithm is similar to the one proposed in
+ *
+ * P. Tsigas and Y. Zhang.
+ * A simple, fast parallel implementation of quicksort and
+ * its performance evaluation on SUN enterprise 10000.
+ * In 11th Euromicro Conference on Parallel, Distributed and
+ * Network-Based Processing, page 372, 2003.
+ *
* This file is a GNU parallel extension to the Standard C++ Library.
