The Disruptor is new open-source concurrency framework, designed as a high performance mechanism for inter-thread messaging. It was developed at LMAX as part of our efforts to build the world's fastest financial exchange. Using the Disruptor as an example, this talk will explain of some of the more detailed and less understood areas of concurrency, such as memory barriers and cache coherency. These concepts are often regarded as scary complex magic only accessible by wizards like Doug Lea and Cliff Click. Our talk will try and demystify them and show that concurrency can be understood by us mere mortal programmers.
