Configuration files

LSF configuration files reference.

Important: Specify any domain names in all uppercase letters in all configuration files.

cshrc.lsf and profile.lsf
The user environment shell files cshrc.lsf and profile.lsf set the LSF operating environment on an LSF host.
hosts
For hosts with multiple IP addresses and different official host names configured at the system level, the LSF hosts file associates the host names and IP addresses in LSF.
install.config
The install.config file contains options for LSF installation and configuration. Use the lsfinstall -f install.config command to install LSF with the options that are specified in the install.config file.
lim.acct
The lim.acct file is the log file for the LSF Load Information Manager (LIM). The lim.acct file contains host load information that is collected and distributed by LIM.
lsb.acct
The lsb.acct file is the batch job log file of LSF.
lsb.applications
The lsb.applications file defines application profiles. Use application profiles to define common parameters for the same type of jobs, including the execution requirements of the applications, the resources they require, and how they should be run and managed.
lsb.events
The LSF batch event log file lsb.events is used to display LSF batch event history and for mbatchd failure recovery.
lsb.globalpolicies
This configuration file defines global policies for multiple clusters.
lsb.hosts
The lsb.hosts file contains host-related configuration information for the server hosts in the cluster. It is also used to define host groups, host partitions, and compute units.
lsb.modules
The lsb.modules file contains configuration information for LSF scheduler and resource broker modules. The file contains only one section, named PluginModule.
lsb.params
The lsb.params file defines general parameters used by the LSF system. This file contains only one section, named Parameters. The mbatchd daemon uses lsb.params for initialization. The file is optional. If not present, the LSF-defined defaults are assumed.
lsb.queues
The lsb.queues file defines batch queues. Numerous controls are available at the queue level to allow cluster administrators to customize site policies.
lsb.reasons
lsb.resources
The lsb.resources file contains configuration information for resource allocation limits, exports, resource usage limits, and guarantee policies. This file is optional.
lsb.serviceclasses
lsb.threshold
The lsb.threshold configuration file defines energy-saving and CPU frequency policies. This file is optional.
lsb.users
The lsb.users file is used to configure user groups, hierarchical fair share for users and user groups, and job slot limits for users and user groups. It is also used to configure account mappings in a multicluster environment.
lsf.acct
lsf.cluster
The cluster configuration file. There is one file for each cluster, called lsf.cluster.cluster_name. The cluster_name suffix is the name of the cluster defined in the Cluster section of the lsf.shared file. All LSF hosts are listed in this file, along with the list of LSF administrators and the installed LSF features.
lsf.conf
The lsf.conf file controls the operation of LSF. The lsf.conf file is created during installation and records all the settings chosen when LSF was installed. The lsf.conf file dictates the location of the specific configuration files and operation of individual servers and applications.
lsf.datamanager
The lsf.datamanager file controls the operation of IBM Spectrum LSF Data Manager features. Each cluster has one LSF data management configuration file, called lsf.datamanager.cluster_name. The cluster_name suffix is the name of the cluster that is defined in the Cluster section of the lsf.shared file. The file is read by the LSF data management daemon dmd. Since one LSF data manager can serve multiple LSF clusters, the contents of this file must be identical on each cluster that shares LSF data manager.
lsf.licensescheduler
The lsf.licensescheduler file contains LSF License Scheduler configuration information. All sections except ProjectGroup are required. In cluster mode, the Project section is also not required.
lsf.shared
The lsf.shared file contains common definitions that are shared by all load sharing clusters defined by lsf.cluster.cluster_name files. This includes lists of cluster names, host types, host models, the special resources available, and external load indices, including indices required to submit jobs using JSDL files. This file is installed by default in the directory defined by LSF_CONFDIR.
lsf.sudoers
lsf.task
lsf.usermapping
Defines the user mapping policy for the bsubmit command.
setup.config
server.config
The server.config file contains options for installing and configuring a server host that can be dynamically added or removed.
