External load indices commands

Commands to submit workload

Command Description
bsub -R "res_req" [-R "res_req"] …
  • Runs the job on a host that meets the specified resource requirements.
  • If you specify a value for a dynamic external resource in the resource requirements string, LSF uses the most recent values that are provided by your elim executables for host selection.
  • For example:
    • Define a dynamic external resource called "usr_tmp" that represents the space available in the /usr/tmp directory.
    • Write an elim executable to report the value of usr_tmp to LSF.
    • To run the job on hosts that have more than 15 MB available in the /usr/tmp directory, run the command bsub -R "usr_tmp > 15" myjob
    • LSF uses the external load index value for usr_tmp to locate a host with more than 15 MB available in the /usr/tmp directory.

Commands to monitor

Command Description
lsload Displays load information for all hosts in the cluster on a per host basis.
lsload -R "res_req" Displays load information for specific resources.

Commands to control

Command Description
  1. lsadmin reconfig
  2. badmin mbdrestart
  3. If you are adding host-based dynamic resources, an administration must also restart all LIMs that are impacted by the configuration change, so that those LIMs can reload configuration and start ELIMs based on the new settings: lsadmin limrestart all
 Applies changes when you modify lsf.shared or lsf.cluster.cluster_name.

Commands to display configuration

Command Description
lsinfo Displays configuration information for all resources, including the external resources that are defined in lsf.shared.
lsinfo -l Displays detailed configuration information for external resources.
lsinfo resource_name … Displays configuration information for the specified resources.
bhosts -s Displays information about numeric shared resources, including which hosts that share each resource.
bhosts -s shared_resource_name … Displays configuration information for the specified resources.
