LSF Version 7.3 - Platform LSF Configuration Reference

The first administrator of the expanded list is considered the primary LSF administrator. The
primary administrator is the owner of the LSF configuration files, as well as the working files
under LSB_SHAREDIR/cluster_name. If the primary administrator is changed, make sure the
owner of the configuration files and the files under LSB_SHAREDIR/cluster_name are changed
as well.
Administrators other than the primary LSF administrator have the same privileges as the
primary LSF administrator except that they do not have permission to change LSF
configuration files. They can perform clusterwide operations on jobs, queues, or hosts in the
system.
For flexibility, each cluster may have its own LSF administrators, identified by a user name,
although the same administrators can be responsible for several clusters.
Use the -l option of the lsclusters command to display all of the administrators within a
cluster.
Windows domain:
•
If the specified user or user group is a domain administrator, member of the Power
Users group or a group with domain administrative privileges, the specified user or user
group must belong to the LSF user domain.
•
If the specified user or user group is a user or user group with a lower degree of privileges
than outlined in the previous point, the user or user group must belong to the LSF user
domain and be part of the Global Admins group.
Windows workgroup
•
If the specified user or user group is not a workgroup administrator, member of the Power
Users group, or a group with administrative privileges on each host, the specified user or
user group must belong to the Local Admins group on each host.
Compatibility
For backwards compatibility, ClusterManager and Manager are synonyms for
ClusterAdmins and ADMINISTRATORS respectively. It is possible to have both sections
present in the same lsf.cluster.cluster_name file to allow daemons from different LSF
versions to share the same file.
Example
The following gives an example of a cluster with two LSF administrators. The user listed first,
user2, is the primary administrator.
Begin ClusterAdmins
ADMINISTRATORS = user2 user7
End ClusterAdmins
Default
lsfadmin
Host section
The Host section is the last section in lsf.cluster.cluster_name and is the only required
section. It lists all the hosts in the cluster and gives configuration information for each host.
The order in which the hosts are listed in this section is important, because the first host listed
becomes the LSF master host. Since the master LIM makes all placement decisions for the
cluster, it should be on a fast machine.
