22 Administering Platform LSF
Host types and host models
Hosts in LSF are characterized by host type and host model.
The following example host type X86_64, with host models Opteron240,
Opteron840, Intel_EM64T, Intel_IA64, 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
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:
◆ Defined in lsf.shared
◆ Mapped to hosts in lsf.cluster.cluster_name
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.
