Content-based publish/subscribe systems have been employed to deal with complex distributed information flows in many applications. It is well recognized that event matching is a fundamental component of such large-scale systems. Event matching searches a space which is composed of all subscriptions. As the scale and complexity of a system grows, the efficiency of event matching becomes more critical...
Event matching is the process of checking high volumes of events against large numbers of subscriptions and is a fundamental issue for the overall performance of a large-scale distributed publish/subscribe system. Most existing algorithms are based on counting satisfied component constraints in each subscription. As the scale of a system grows, these algorithms inevitably suffer from performance degradation...

Load balancing plays a key role in workload scheduling policies which count in the performance improvement of parallel applications. A critical problem of load balancing is to make a reasonable definition of load index. Unfortunately, few studies provided enough scientific justifications for the choice of load indices. In this paper, a reasonable approach for defining a load index based on factor...
