Clusters of nondedicated heterogeneous nodes promise high utilization and performance. A market-based resource allocation allows effective and decentralized management and motivates participants to contribute to the functionality of a cluster. Major issues for a user who wants to execute a task on a nondedicated cluster are to ensure data integrity and evaluate reasonably a target processor. We have proposed an auditing mechanism that allows a user to establish suitable prices of cluster computational resources in an untrusted system environment of heteroge neous nondedicated clusters. In a process of price evalu ation, a user can detect resources that behave incorrectly.
