IBM Platform LSF 9.1.3 Fix 328121 Readme File

Abstract

Solution to show the settings for pending time, interactive jobs, exclusive jobs, and run time limit when specifying the bjobs customized output.

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 328121 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

Add support to show the settings for pending time, interactive jobs, exclusive jobs, and run time limit by either running bjobs -o pend_time, bjobs -o interactive, bjobs -o exclusive, bjobs -o runtimelimit/rtlimit or by adding pend_time, interactive, exclusive, runtimelimit/rtlimit to LSB_BJOBS_FORMAT in lsf.conf.

For example:

bjobs -o “jobid pend_time interactive exclusive runtimelimit”

JOBID PEND_TIME INTERACTIVE EXCLUSIVE RUNTIMELIMIT

1 20 Y N 100.0/host1

2 10 N Y -

1. For a pending job, the PEND_TIME is the current time minus the job’s submission time.

2. For a dispatched (running and suspending) job, the PEND_TIME is the job’s start time minus the job’s submission time.

3. For a requeued, migrated, or rerun job, the PEND_TIME is the current time (re-dispatched time) minus the job’s requeued, migrated, or rerun time.

4. Jobs that are submitted with following bsub options are treated as interactive jobs. -I, -Ip, -Is, -IS, -ISp, -ISs, -IX.

5. bjobs -o exclusive shows Y for jobs that are submitted with -x option, a compute unit exclusive request, or an affinity exclusive request.

6. The RUNTIMELIMIT is the merged value of job level run time limit assignment, the application level run time limit setting and the queue level run time limit setting. If ABS_RUNLIMIT is enabled, the RUNTIMELIMIT is not normalized by the host CPU factor.

7. For IBM Platform LSF MultiCluster ("MultiCluster") with the job level run time limit specified, "bjobs -o runtimelimit" shows the normalized run time on both the submission cluster and the execution cluster. Defining the run time limit at the application or queue level in the submission cluster does not affect the job’s run time on the job execution cluster, so defining it in the submission cluster is meaningless. However, when defining the run time limit at the application or queue level in the submission cluster, running "bjobs -o runtimelimit" in the submission cluster still shows the combined run time limit of the submission cluster as being different from the effective run time limit at the execution cluster, while running "bjobs -o runtimelimit" in the execution cluster shows the effective run time limit.
