  abstract=      "PIERS is a deadlock free virtual routing system developed
     for distributed concurrent applications. It deliberately
     exploits the advantages gained by allowing cycles to occur
     in the channel dependency graph and incorporates the cycles
     into the routing algorithm. It directly interfaces with the
     user's application and uses the existing OCCAM channel
     primitives. The paper describes how this cyclic
     routingalgorithm operates and how deadlock is averted. It
     describes how the routing system is implemented, presents
     the performance figures obtained and summarises the network
     configuration utility written to integrate the communication
     harness with the user's application."
