%X 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.
