Four important LSF configuration files
LSF configuration administered through several configuration files, which you use to
modify the behavior of your cluster. The four most important files you will work with
most often are:
◆ LSF_CONFDIR/lsf.conf
◆ LSF_CONFDIR/lsf.cluster.cluster_name
◆ LSF_CONFDIR/lsf.shared
◆ LSB_CONFDIR/cluster_name/configdir/lsb.queues
These files are created during LSF installation according to the options you specified in
the
install.config file. After installation, you can change the configuration
parameters in these files to suit the needs of your site.
Who owns these
files
Except for LSF_CONFDIR/lsf.conf, which is owned by root, all of these files are
owned by the primary LSF administrator, and readable by all cluster users.
lsf.conf
The most important file in LSF. It is owned by root and contains the paths to the LSF
configuration directories, log directories, libraries, license file and other global
configuration information. The location of
lsf.conf is defined by the LSF_ENVDIR
variable. If LSF cannot find this file, it cannot start properly.
By default, LSF checks the directory defined by LSF_ENVDIR
for lsf.conf. If
lsf.conf is not in LSF_ENVDIR, LSF looks for it in/etc.
lsf.cluster.cluster_name
Defines the host names, models, and types of all of the hosts in the LSF cluster. It also
defines the user names of the LSF administrators, and the locations of different shared
resources for one LSF cluster.
lsf.shared
This file is like a dictionary that defines all the keywords used by the LSF cluster. You
can add your own keywords to specify the names of resources or host types.
lsb.queues
Defines the LSF batch queues and their parameters for one LSF cluster.
Default directory structure
The following diagram illustrates a typical directory structure for an example installation.
Depending on which products you have installed and platforms you have selected, your
directory structure may vary.
