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.
