Understanding and Using Atomic Memory Operations
Abstract:

Atomic memory operations provide powerful communication and coordination capabilities for parallel programs, including the well-known operations compare-and-swap and fetch-and-add. The atomic operations enable the creation of parallel algorithms and data structures that would otherwise be very difficult (or impossible) to express without them - for example: shared parallel data structures, parallel data aggregation, and control primitives such as semaphores and mutexes. In this talk we will use examples to describe atomic operations, explain how they work, and discuss performance considerations and pitfalls when using them.
