This repository contains SnapTree, a concurrent AVL tree with fast cloning, snapshots, and consistent iteration. It is described in the paper "A Practical Concurrent Binary Search Tree", by N. Bronson, J. Casper, H. Chafi, and K. Olukotun, published in PPoPP'10.

SnapTreeMap is a drop-in replacement for ConcurrentSkipListMap, with the additional guarantee that clone() is atomic and iteration has snapshot isolation. For more details see http://ppl.stanford.edu/papers/ppopp207-bronson.pdf
