All computers that run the same operating system on the same computer architecture
are of the same type—in other words, binary-compatible with each other.
Each host type usually requires a different set of LSF binary files.
Commands
◆
lsinfo -t—View all host types defined in lsf.shared
Configuration
◆
Defined in lsf.shared
◆
Mapped to hosts in lsf.cluster.cluster_name
Host model
The combination of host type and CPU speed (CPU factor) of the computer.
All hosts of the same relative speed are assigned the same host model.
The CPU factor is taken into consideration when jobs are being dispatched.
Commands
◆
lsinfo -m—View a list of currently running models
◆
lsinfo -M—View all models defined in lsf.shared
Configuration

Users and administrators
LSF user
A user account that has permission to submit jobs to the LSF cluster.
LSF administrator
In general, you must be an LSF administrator to perform operations that will affect
other LSF users. Each cluster has one primary LSF administrator, specified during LSF
installation. You can also configure additional administrators at the cluster level and at
the queue level.
Primary LSF
administrator
The first cluster administrator specified during installation and first administrator listed
in
lsf.cluster.cluster_name. The primary LSF administrator account owns the
configuration and log files. The primary LSF administrator has permission to perform
clusterwide operations, change configuration files, reconfigure the cluster, and control
jobs submitted by all users.
Cluster
administrator
May be specified during LSF installation or configured after installation. Cluster
administrators can perform administrative operations on all jobs and queues in the
cluster. Cluster administrators have the same cluster-wide operational privileges as the
primary LSF administrator except that they do not necessarily have permission to
change LSF configuration files.
For example, a cluster administrator can create an LSF host group, submit a job to any
queue, or terminate another user’s job.
Queue
administrator
An LSF administrator user account that has administrative permissions limited to a
specified queue. For example, an LSF queue administrator can perform administrative
operations on the specified queue, or on jobs running in the specified queue, but cannot
change LSF configuration or operate on LSF daemons.
