LSF Version 7.3 - Platform LSF Configuration Reference

Scope
Applicability Details
Operating system
•
UNIX
•
Windows
•
A mix of UNIX and Windows hosts
Dependencies
•
UNIX and Windows user accounts must be valid on all hosts in the cluster and must
have the correct permissions to successfully run jobs.
•
All elim executables run under the same user account as the load information
manager (LIM)—by default, the LSF administrator (lsfadmin) account.
•
External dynamic resources (host-based or shared) must be defined in
lsf.shared.
Configuration to enable external load indices
To enable the use of external load indices, you must
•
Define the dynamic external resources in lsf.shared. By default, these resources are
host-based (local to each host) until the LSF administrator configures a resource-to-host-
mapping in the ResourceMap section of lsf.cluster.cluster_name. The presence of
the dynamic external resource in lsf.shared and lsf.cluster.cluster_name
triggers LSF to start the elim executables.
•
Map the external resources to hosts in your cluster in lsf.cluster.cluster_name.
Important:
You must run the command lsadmin reconfig followed by
badmin mbdrestart to apply changes.
•
Create one or more elim executables in the directory specified by the parameter
LSF_SERVERDIR. LSF does not include a default elim; you should write your own
executable to meet the requirements of your site. The section Create an elim executable
provides guidelines for writing an elim.
Define a dynamic external resource
To define a dynamic external resource for which elim collects an external load index value,
define the following parameters in the Resource section of lsf.shared:
Feature: External load indices
