1. A method for implementing a stream processing computer architecture, comprising: forming a super node cluster of processors, each of the processors comprising at least one physical computation node within the super node cluster of processors, the super node cluster of processors formed by identifying relationships among processors with respect to associated data streams and using a multiplexer to aggregate and separate corresponding data streams between respective processors, wherein processors in the super node cluster of processors are communicatively coupled to one another via a local interconnection means; communicatively coupling the super node cluster of processors to an optical circuit network, the optical circuit network comprising one or more optical external links and at least one optical circuit switch, the super node cluster of processors coupled to the optical circuit switch via the one or multiple optical external links, the optical external links each using multiple optical wavelengths in a wavelength division multiplexer, the optical circuit switch communicatively coupled to at least one other super node cluster of processors that respectively includes at least one other physical computation node, via one or more optical external links from the other super node cluster of processors, wherein the super node cluster of processors and the optical circuit network collectively represent a stream computer processing system; generating a stream computation graph including kernels and data streams, the kernels representing software code elements that perform computations on one or more of the data streams that are input to corresponding kernels; mapping components of the stream computation graph to physical components of the stream computer processing system, comprising: assigning the kernels to the super node clusters and to respective physical computation nodes of each of the super node cluster of processors; assigning data stream traffic between the kernels to the local interconnection means when the respective data stream is between physical computation nodes in the same super node cluster of processors; assigning data stream traffic between the kernels to the optical external links when the respective data stream is between physical computation nodes in different super node cluster of processors; and configuring the optical circuit switch to provide connectivity between the super node clusters of processors corresponding to the assignments, via the optical external links; and executing operations on the stream computer processing system in accordance with the stream computation graph.
