6.2.4 Host Selection

Assuming that acceptable values for each host's workload are available, a decision has to be made to which one of the registered hosts a job should be submitted. This decision basically depends on three criteria:

• The system command to be invoked must be available on a host.
• A host has to be reachable and its load must not exceed a certain limit after the job has been submitted.
• Finally the estimated performance of the selected host has to be superior compared to the remaining hosts.
