Contention for the shared heap limits the obtainable speedup in parallel algorithms using this data structure as a priority queue. An approach that allows concurrent insertions and deletions on the heap in a shared-memory multiprocessor is presented. The scheme retains the strict priority ordering of the serial-access heap algorithms, i.e. a delete operation returns the best key of all keys tha
