Make any algorithm lock-free with this one crazy trick - Paper Trail
Lock-free algorithms often operate by having several versions of a data structure in use at one time. The general pattern is that you can prepare an update to a data structure, and then use a machine primitive to atomically install the update by changing a pointer. This means that all subsequent readers will follow the pointer to its new location – for example, to a new node in a linked-list – but
Simple, Fast, and Practical Non-Blocking and Blocking Concurrent Queue Algorithms
Simple, Fast, and Practical Non-Blocking and Blocking Concurrent Queue Algorithms Simple, Fast, and Practical Non-Blocking and Blocking Concurrent Queue Algorithms by Maged M. Michael and Michael L. Scott This paper appeared in the proceedings of PODC '96. PDF file (180KB). Pseudocode. Abstract Drawing ideas from previous authors, we present a new non-blocking concurrent queue algorithm and a new

The World's Simplest Lock-Free Hash Table
A lock-free hash table is a double-edged sword. There are applications where it can provide a performance improvement that would be impossible to achieve otherwise. The downside is that it’s complicated. The first working lock-free hash table I heard about was written in Java by Dr. Cliff Click. He released the source code back in 2007 and gave a presentation about it at Google that same year. Whe
