Platform LSF Licensing
Partial Licensing
This section applies to permanent licenses. Read this if you have a cluster in which
not all of the hosts will require licenses for the same LSF products. In this section,
you will learn how to save money through distributing your licenses efficiently.
Not all hosts in the cluster need to be licensed for the same set of LSF products. For
example, some hosts might be licensed only for Platform LSF Make, while others
may also be licensed to run Platform MultiCluster. All hosts in the cluster remain
licensed regardless of the license configuration of the rest of the cluster. If hosts
become unavailable or new hosts are added, licenses are redistributed according to
the new configuration.
This allows you to purchase only as many licenses as you need, rather than enabling
the entire cluster for products that are only needed by a few hosts.
However, many LSF products do not support partial licensing. They must be
enabled for the entire cluster, or not at all.
Setting priority for license distribution
This describes how to define the order your licenses are given out to hosts.
To enable LSF server hosts to run partially licensed LSF products, edit the
Host
section of
LSF_CONFDIR/lsf.cluster.cluster_name and include the product
names in the RESOURCES column for specific hosts. When the LSF cluster starts,
the master LIM reads the
lsf.cluster.cluster_name file and determines the LSF
products that each host is licensed to use.
For a permanent license, the license manager retrieves the appropriate licenses for
the cluster, and distributes the licenses to the hosts in the order they are listed in
lsf.cluster.cluster_name. You can see the order in which licenses are
distributed with the command
lshosts.
Displaying licensed products
This describes how to view what products are licensed for any host in the cluster.
Use the
lshosts -l command.
