This paper present a comparison of scheduling algorithms applied to the context of load balancing the query traffic on distributed inverted les. Number of algorithms is implemented taken from the literature. The paper proposes a novel method to formulate the cost of query processing so that these algorithms can be used to schedule queries onto processors. Measuring load balance is avoided at the search engine side because this can lead to imprecise evaluation. This method is based on the simulation of a bulk-synchronous parallel computer at the broker machine side. This simulation determines an optimal way of processing the queries and provides a stable baseline upon which both the broker and search engine can tune their operation in accordance with the observed query traffic.
