In this paper we develop an optimal cache-oblivious priority queue data
structure, supporting insertion, deletion, and deletemin operations in
O((1/B) logM/B (N/B))
amortized memory transfers, where M and B are the memory and
block transfer sizes of any two consecutive levels of a multilevel memory
hierarchy. In a cache-oblivious data structure, M and B are not
used in the description of the structure. The bounds match the bounds of
several previously developed external-memory (cache-aware) priority queue data
structures, which all rely crucially on knowledge about M and B.
Priority queues are a critical component in many of the best known
external-memory graph algorithms, and using our cache-oblivious priority queue
we develop several cache-oblivious graph algorithms.
