A group of computers (hosts) running LSF that work together as a single unit, combining computing power and sharing workload and resources. A cluster provides a single-system image for a network of computing resources.
Hosts can be grouped into clusters in a number of ways. A cluster could contain:
A clusterwide container for jobs. All jobs wait in queues until they are scheduled and dispatched to hosts.
Queues do not correspond to individual hosts; each queue can use all server hosts in the cluster, or a configured subset of the server hosts.
When you submit a job to a queue, you do not need to specify an execution host. LSF dispatches the job to the best available execution host in the cluster to run that job.
Queues implement different job scheduling and control policies.
