It was either 'go with the title or come up with another one', and I was too tired to argue. By the way, the paper was really an excuse to document this IJulia notebook. http://nbviewer.ipython.org/urls/raw.github.com/jiahao/ijulia-notebooks/master/2014-08-06-parallel-prefix.ipynb http://nbviewer.ipython.org/urls/raw.github.com/jiahao/ijuli... If you run it on your local machine, one of the cells has an interactive slider that lets you control the breadth of the parallel prefix tree you generate.
