摘要:
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.
摘要:
A method, apparatus, and computer program product for scheduling stream-based applications in a distributed computer system with configurable networks are provided. The method includes choosing, at a highest temporal level, jobs that will run, an optimal template alternative for the jobs that will run, network topology, and candidate processing nodes for processing elements of the optimal template alternative for each running job to maximize importance of work performed by the system. The method further includes making, at a medium temporal level, fractional allocations and re-allocations of the candidate processing elements to the processing nodes in the system to react to changing importance of the work. The method also includes revising, at a lowest temporal level, the fractional allocations and re-allocations on a continual basis to react to burstiness of the work, and to differences between projected and real progress of the work.
摘要:
Optical cubes and optical cube assemblies for directing optical beams are provided. The optical cubes are optically transparent modules that can be adapted to reflect, transmit, and/or partially reflect and transmit optical beams. The optical cubes may include bi-direction or multi-direction beam directing elements for directing optical beams. The optical cube assemblies may include flexible chip assemblies attached to optical cubes. The chip assemblies may include vertical cavity surface-emitting lasers for emitting optical beams or receivers for receiving optical beams mounted on a flexible and electrical interconnect mounting assembly.
