A Scalable Implementation of

Globally-shared Queues*

R. Lyndon While

This paper describes the use of combining networks to implement globally-shared first-in-first-out queues in scalable fashion. Up to N processors can access a queue in one time cycle, N being the maximum length of the queue. No critical code sections are required, no waiting is necessary and no bottleneck is created.
