Abstract

We study the complexity of a generalization of the unit-execution-time multiprocessor scheduling problem under precedence constraints, in which the number of communication arcs is also minimized. Most versions of the problem are shown NP-complete, and two polynomial algorithms are presented for specialized cases.
