Abstract
We study practical techniques for implementing the FIFO queue abstract data type using lock-free data structures, which synchronize the operations of concurrent processes without the use of mutual exclusion. Two new algorithms based on linked lists and arrays are presented. We also propose a new solution to the ABA problem associated with the Compare&Swap instruction. The performance of our linked list algorithm is compared several other lock-free queue implementations, as well as more conventional locking techniques. 1 Introduction Concurrent access to a data structure shared among several processes must be synchronized in order to avoid conflicting updates. Conventionally this is done using mutual exclusion; processes modify the data structure only inside a critical section of code, within which the process is guaranteed exclusive access to the data structure. Typically, on a multiprocessor, critical sections are guarded with a spin-lock . We will refer to all methods using mutual ...
