In this paper we develop an optimal cache-oblivious priority queue data
structure, supporting insertion, deletion, and deletemin operations in
*O*((1/*B*) log_{M/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. **Length**:- The paper is 9 pages.
