Viewing LSF cluster information

Use the lsid command to display the version of LSF, the name of your cluster, and the current management host.

My cluster name is lsf10

Use the lsclusters command to find out who your cluster administrator is and see a summary of your cluster.

lsclusters
CLUSTER_NAME   STATUS   MASTER_HOST    ADMIN        HOSTS     SERVERS

Use the bparams command to display the generic configuration parameters of LSF.

1. The bparams command shows default queues, job dispatch interval, job checking interval, and job acceptance interval.

   bparams
   Default Queues:  normal idle
   MBD_SLEEP_TIME used for calculations: 20 seconds
   Job Checking Interval:  15 seconds
   Job Accepting Interval:  20 seconds
   

2. Use the bparams -l command to display the information in long format, which gives a brief description of each parameter and the name of the parameter as it appears in the lsb.params file.

   bparams -l
   System default queues for automatic queue selection:
       DEFAULT_QUEUE = normal idle
   Amount of time in seconds used for calculating parameter values:
       MBD_SLEEP_TIME = 20 (seconds)
   The interval for checking jobs by server batch daemon:
       SBD_SLEEP_TIME = 15 (seconds)
   The interval for a host to accept two batch jobs subsequently:
       JOB_ACCEPT_INTERVAL = 1 (* MBD_SLEEP_TIME)
   The idle time of a host for resuming pg suspended jobs:
       PG_SUSP_IT = 180 (seconds)
   The amount of time during which finished jobs are kept in core:
       CLEAN_PERIOD = 3600 (seconds)
   The maximum number of finished jobs that are logged in current event file:
       MAX_JOB_NUM = 2000
   The maximum number of retries for reaching a server batch daemon:
       MAX_SBD_FAIL = 3
   The number of hours of resource consumption history:
       HIST_HOURS = 5
   The default project assigned to jobs.
       DEFAULT_PROJECT = default
   Sync up host status with management host LIM is enabled:
   LSB_SYNC_HOST_STAT_LIM = Y
   MBD child query processes will only run on the following CPUs:
   MBD_QUERY_CPUS=1 2 3
   

3. Use the bparams -a command to display all configuration parameters and their values in the lsb.params file.
   For example,

   bparams -a
        MBD_SLEEP_TIME = 20
        SBD_SLEEP_TIME = 15
        JOB_ACCEPT_INTERVAL = 1
        SUB_TRY_INTERVAL = 60
        LSB_SYNC_HOST_STAT_LIM =  N
        MAX_JOBINFO_QUERY_PERIOD = 2147483647
        PEND_REASON_UPDATE_INTERVAL = 30
        ...
   

Use the badmin showconf mbd command and the lsadmin showconf command to show current cluster configuration settings.

1. Display all configuration settings for running LSF daemons.
   • Use the lsadmin showconf command to display all configured parameters and their values in the lsf.conf or ego.conf file for LIM.
   • Use the badmin showconf mbd command or the badmin showconf sbd command to display all configured parameters and their values in the lsf.conf or ego.conf file for the mbatchd and sbatchd daemons.

   In IBM Spectrum LSF multicluster capability, the parameters apply to the local cluster only.

2. Display mbatchd and root sbatchd daemon configuration.
   • Use the badmin showconf mbd command to display the parameters that are configured in the lsf.conf or ego.conf file that apply to the mbatchd daemon.
   • Use the badmin showconf sbd command to display the parameters that are configured in the lsf.conf or ego.conf file that apply to the root sbatchd daemon.

Use the badmin showstatus command to display a summary of the current LSF runtime information.

% badmin showstatus
