Readme file for IBM® Spectrum LSF 10.1 Fix 601930

Abstract

P105080. This fix introduces the BWAIT_ERR_RETRY="RETRY_CNT[integer] INTERVAL[integer]" environment variable to control bwait command retries when user authentication fails on the client side.

Description

Readme documentation for IBM Spectrum LSF 10.1 Fix 601930 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

In some environments, LDAP is not stable enough to verify the username. The bwait command can fail and exit when sending re-registeration requests . This fix introduces the BWAIT_ERR_RETRY environment variable:

Syntax

BWAIT_ERR_RETRY="RETRY_CNT[integer] INTERVAL[integer]"

Description

Restricts the number of times that the bwait command retries to authenticate users, and the interval between each retry, when user authentication fails on the client side.

This parameter includes two keywords:

RETRY_CNT: The times that the bwait command retries to authenticate. Valid values are a value from 0 to 2147483646. If only RETRY_CNT is defined, the bwait command will retry without waiting if user authentication fails. A value of 0 means there are not retries.

INTERVAL: The amount of time, in seconds, to wait between retrying to verify each user. Valid values are a value of 0 to 2147483646. The INTERVAL keyword should be used along with the RETRY_CNT keyword; otherwise, the interval will be ignored. A value of 0 means there is no delay before the next retry.

Default

Undefined.

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 above. You can download LSF 10.1 Fix Pack 12 from https://www.ibm.com/support/fixcentral. Search for build600488. Contact IBM LSF Support if you have any questions or problems with installing Fix Pack 12.

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 if these GPU parameters not configured in the lsf.conf configuration file, the default values will be used, and 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
