Lock-Free Red-Black Trees Using CAS
... If there is contention, all but one concurrent process accessing the shared data must “roll-back” and redo its computation using the updated data. Optimistic techniques can be divided into “lock-free” and, the stronger, “wait-free” techniques. Our focus is on lock-free techniques. Concurrent program ...

Let us therefore reduce the Put operation to the problem of finding the correct location to insert a given priority p. This location is the index i, 0 ≤ i ≤ size, such that ...
