Parallel searching in generalized monge arrays with applications
Abstract
This paper investigates the parallel time and processor complexities of several searching problems involving Monge and Monge-composite arrays. We present array-searching algorithms for concurrent-read-concurrent-write (CRCW) PRAMs, concurrent-read-exclusive-write (CREW) PRAMs, hypercubes, cube-connected-cycles, and shuffle-exchange networks. All these algorithms run in optimal time, and their processor-time products are all within an O(lg n) factor of the worst-case sequential bounds. Several applications of these algorithms are also given. Two applications improve previous results substantially, and the others provide novel parallel algorithms for problems not previously considered.
