Abstract
A first in, first out queue uses a sequence of arrays to store elements in the queue. The arrays are constructed using a lock free queue, and within each array, a lock free mechanism may be used to enqueue and dequeue elements. Many embodiments may use atomic operations to ensure successful placement of elements in the queue, as well as remove elements from the queue. The atomic operations may be used within a loop until successful.
