Host groups

Host groups gather similar resources to the same group of hosts (for example, all hosts with big memory)- Use host groups to manage dedicated resources for a single organization or to share resources across organizations. You can add limits to host groups, or define host groups in queues to constrain jobs for a scheduling policy that is defined over a specific set of hosts.

You can define a host group within LSF or use an external executable to retrieve host group members.

Use bhosts to view a list of existing hosts. Use bmgroup to view host group membership.

Where to use host groups

LSF host groups can be used in defining the following parameters in LSF configuration files:

  • HOSTS in lsb.queues for authorized hosts for the queue
  • HOSTS in lsb.hosts in the HostPartition section to list host groups that are members of the host partition
