This paper proposes a new concurrent heap algorithm, based on a stateless shape property, which efficiently maintains balance during insert and removeMin operations implemented with hand-over-hand locking. It also provides a O(1) linearizable snapshot operation based on lazy copy-on-write semantics. Such snapshots can be used to provide consistent views of the heap during iteration, as well as ...

This paper studies the performance of two mechanisms to implement such quotas in a lab experiment. The first mechanism is a simplified version of the mecha...
