Abstract

In data stream management systems as long as streams of data arrive to the system, stored queries are executed on these data. Regarding high workload, high processing capacity is required, leading to consider multiple processors to cope with it. PARTITIONING approach, one of the main methods in MULTIPROCESSOR REAL-TIME SCHEDULING, bind each query to one of processors based on its UTILIZATION, ratio of estimated execution time to period, and instances of each query which should be completed under defined deadline can only be executed on specified processor. Each query which could not be assigned to any processor can be split based on UTILIZATION of processors and spread among them, causing to get closer to optimum result. This system has been examined with real network data, showing lower miss ratio and higher UTILIZATION in comparison to simple PARTITIONING approach.
