Skiplist-based concurrent priority queues
N Shavit, I Lotan - Proceedings 14th International Parallel and …, 2000 - ieeexplore.ieee.org
This paper addresses the problem of designing scalable concurrent priority queues for large
scale multiprocessors machines with up to several hundred processors. Priority queues are …

Efficient step** algorithms and implementations for parallel shortest paths
The single-source shortest-path (SSSP) problem is a notoriously hard problem in the
parallel context. In practice, the Δ-step** algorithm of Meyer and Sanders has been widely …

Multiqueues: Simple relaxed concurrent priority queues
We present a simple, concurrent data structure that approximates the behavior of a priority
queue and that gives very good performance guarantees. We also discuss models for the …

Fast priority queues for parallel branch-and-bound
P Sanders - Parallel Algorithms for Irregularly Structured Problems …, 1995 - Springer
Currently used parallel best first branch-and-bound algorithms either suffer from contention
at a centralized priority queue or can only approximate the best first strategy. Bottleneck free …
