Abstract

Integer sorting is a special case of the sorting problem, where the elements have integer values in the range [0,n–1]. We evaluate the behavior and performance of two parallel integer sorting algorithms in practice. We have used Ada tasks facilities to simulate the parallel sorting algorithms on a machine consisting of 4-processors. Both algorithms are based on self-index method on EREW PRAM [3,6]. Also, we study the scalability of the two parallel algorithms and compare between them.
