About Platform LSF
Host types and host models
Hosts in LSF are characterized by host type and host model.
The following example has HP hosts. The host type is HPPA. Host models can
be HPN4000, HPJ210, etc.

Host type
The combination of operating system version and host CPU architecture.
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
Host model
Configuration
◆ Defined in lsf.shared
◆ Mapped to hosts in lsf.cluster.cluster_name
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
◆
Users and administrators
LSF user
LSF administrator
Primary LSF
administrator
◆
lsinfo -m—View a list of currently running models
lsinfo -M—View all models defined in lsf.shared
Configuration
◆ Defined in lsf.shared
◆ Mapped to hosts in lsf.cluster.cluster_name
A user account that has permission to submit jobs to the LSF cluster.
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.
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.
