Beschreibung
Zusammenfassung:	A stream processing computer architecture includes creating a stream computer processing (SCP) system by forming a super node cluster of processors representing physical computation nodes ("nodes"), communicatively coupling the processors via a local interconnection means ("interconnect"), and communicatively coupling the cluster to an optical circuit switch (OCS), via optical external links ("links"). The OCS is communicatively coupled to another cluster of processors via the links. The method also includes generating a stream computation graph including kernels and data streams, and mapping the graph to the SCP system, which includes assigning the kernels to the clusters and respective nodes, assigning data stream traffic between the kernels to the interconnection when the data stream is between nodes in the same cluster, and assigning traffic between the kernels to the links when the data stream is between nodes in different clusters.
