Working with Hosts
View normalized ratings
1 Run lsload -N to display normalized ratings.
LSF uses a normalized CPU performance rating to decide which host has the
most available CPU power. Hosts in your cluster are displayed in order from
best to worst. Normalized CPU run queue length values are based on an
estimate of the time it would take each host to run one additional unit of work,
given that an unloaded host with CPU factor 1 runs one unit of work in one
unit of time.
Tune CPU factors
1 Log in as the LSF administrator on any host in the cluster.
