Systems and methods for changing computational tasks on computation nodes to minimize processing time variation

摘要

Systems and methods are disclosed to process streaming data units (tuples) for an application using a plurality of processing units, the application have a predetermined processing time requirement, by changing an operator-set applied to the tuple by a processing unit, on a tuple-by-tuple basis; estimating code requirement for potential operators based on processing unit capability; and assigning the potential operators to the processing units.
