Abstract

In many of recent applications data are received as infinite, continuous, rapid and time varying data streams. Real-time processing of queries over such streams is essential in most of the applications. Single processor systems are not capable to provide the desired speed to be real-time. Parallelism over multiprocessors can be used to handle this deficit. In such a system, a multiprocessor real-time scheduling algorithm must be used. Generally, multiprocessor real-time scheduling algorithms fall into two approaches: Partitioning or Global. The partitioning approach has acceptable overhead but can NOT be optimal. The global approach can be but it has considerable overheads.

In this paper, a multiprocessor real-time scheduling algorithm for a DSMS is proposed that employs hybrid approach. It is shown that it is optimal while has minimum overheads. Also, simulation results illustrate that the proposed hybrid multiprocessor real-time scheduling algorithm outperforms algorithms that use either portioning approach or global approach.
