Abstract
Describes a new updated version of the data structure parallel heap. Employing p processors, a parallel heap allows detections of Theta (p) highest-priority items and insertion of Theta (p) new items each in O(logn) time on an EREW PRAM where n is the size of the parallel heap. Furthermore, it can efficiently utilize processors in the range 1 through n. This version does not require dedicated maintenance processors, and performs insertion and deletion in place.
