1. A method of parallel processing on a computer array comprising the steps of: creating a virtual parallel processing computer system comprising a plurality of parallel processing units; creating programs for each of said parallel processing units wherein each of said programs performs a predetermined function on predetermined data; determining the topology of the physical hardware configuration on which said virtual parallel processing computer system will execute said programs, said topology having at least one computing node; allocating at least one of said parallel processing units to at least one of said computing nodes based upon a distribution algorithm; transferring said programs and said data to said computing nodes for each of said parallel processing units; and executing said programs for said parallel processing units on said computing nodes.
