Readme file for IBM® Spectrum LSF 10.1 Fix 602278
Abstract
P105260. This fix addresses the issue where LSF creates duplicate jobs when the mbatchd daemon is busy.
Description
Readme documentation for IBM Spectrum LSF 10.1 Fix 602278 including installation-related instructions, prerequisites and co-requisites, and list of fixes.
This fix addresses the following issue:
If the mbatchd daemon in a cluster is busy (for example, processing bconf command requests), the bsub command might keep retrying the command after reaching the timeout (as defined in the LSB_API_RECVTIMEOUT parameter in the lsf.conf file). The bsub command can send the job requests multiple times under a special condition, which causes LSF to create duplicate jobs.

5. Installation and configuration
Before you install
LSF_TOP is the full path to the top-level installation directory of LSF.
1. Before you apply this fix, ensure that you installed LSF 10.1 Fix Pack 12 or later. You can download LSF 10.1 Fix Pack 12 or later from https://www.ibm.com/support/fixcentral.
2. Starting
in LSF 10.1 Fix Pack 13, the default values of the following three GPU
parameters are changed to:
LSF_GPU_AUTOCONFIG=Y
LSB_GPU_NEW_SYNTAX=extend
LSF_GPU_RESOURCE_IGNORE=Y
If you have Fix Pack 13 installed, and these GPU parameters not
configured in the lsf.conf
configuration file will take the default values. The parameters already
configured in the lsf.conf file
will not be affected.
If you want to keep the former GPU behavior, and if any of the three
parameters are missing in the lsf.conf
configuration file, you must explicitly configure the following default
settings that are defined in Fix Pack 12 or earlier:
LSF_GPU_AUTOCONFIG=N
LSB_GPU_NEW_SYNTAX=N
LSF_GPU_RESOURCE_IGNORE=N
