Abstract
Deadlock prevention is usually realized by imposing strong restrictions on packet transmissions in the network so that the resulting deadlock free routing algorithms are not optimal with respect to resources utilization. Optimality request can be satisfied by forbidding transmissions only when they would bring the network into a configuration that will necessarily evolve into a deadlock. Hence, optimal deadlock avoidance is closely related to deadlock prediction. In this paper it is shown that wormhole deadlock prediction is an hard problem. Such result is proved with respect to both static and dynamic routing.
期刊介绍：
Parallel Processing Letters (PPL) aims to rapidly disseminate results on a worldwide basis in the field of parallel processing in the form of short papers. It fills the need for an information vehicle which can convey recent achievements and further the exchange of scientific information in the field. This journal has a wide scope and topics covered included: - design and analysis of parallel and distributed algorithms - theory of parallel computation - parallel programming languages - parallel programming environments - parallel architectures and VLSI circuits
