  abstract=      "For problems that require a small database a processor farm
     model was proposed by May and Sheppard, and has subsequently
     had much success. Here, we assume that the database is too
     large to store completely at each node of the farm and
     consequently, data must be communicated throughout the
     network during the execution of a problem. The processor
     farm model is extended to allow work tasks to be completed
     when data items not resident locally at a node can be
     obtained by making a request for data across the network.
     The farm model is further extended by configuring the system
     as a tree topology. The extended farm topology is evaluated
     by using a set of graphics benchmark problems. Benchmark
     results are given for a tree farm of upto fifteen worker
     processors."
