GROUP_DISTRIBUTION and DISTRIBUTION are mutually exclusive. If they are
both defined in the same feature, the License Scheduler daemon returns an error and
ignores this feature.
Examples DISTRIBUTION=wanserver (Lp1 1 Lp2 1 Lp3 1 Lp4 1)
In this example, the service domain named wanserver shares licenses equally among
four License Scheduler projects. If all projects are competing for a total of eight licenses,
each project is entitled to two licenses at all times. If all projects are competing for only
two licenses in total, each project is entitled to a license half the time.
DISTRIBUTION=lanserver1 (Lp1 1 Lp2 2/6)
In this example, the service domain named lanserver1 allows Lp1 to use one third
of the available licenses and
Lp2 can use two thirds of the licenses. However, Lp2 is
always entitled to six licenses, and can preempt another project to get the licenses
immediately if they are needed. If the projects are competing for a total of 12 licenses,
Lp2 is entitled to eight licenses (six on demand, and two more as soon as they are free).
If the projects are competing for only six licenses in total,
Lp2 is entitled to all of them,
and
Lp1 can only use licenses when Lp2 does not need them.
ALLOCATION
Syntax
ALLOCATION=
project_name (cluster_name [number_shares] ... )] ...
◆ cluster_name
Specify LSF cluster names that licenses are to be allocated to.
◆ project_name
Specify a License Scheduler project (described in the PROJECTS section) that is
allowed to use the licenses.
◆ number_shares
Specify a positive integer representing the number of shares assigned to the cluster.
The number of shares assigned to a cluster is only meaningful when you compare it
to the number assigned to other clusters. The total number of shares is the sum of
the shares assigned to each cluster.
Description
Defines the allocation of license features across clusters and between LSF jobs and non-
LSF interactive jobs.
ALLOCATION ignores the global setting of the
ENABLE_INTERACTIVE parameter
because
ALLOCATION is configured for the license feature.
You can configure the allocation of license shares to:
◆ Change the share number between clusters for a feature
◆ Limit the scope of license usage and change the share number between LSF jobs
and interactive tasks for a feature
To manage interactive (non-LSF) tasks in License Scheduler projects, you require the
LSF Task Manager,
taskman. The Task Manager utility is supported by but not
shipped with License Scheduler. For more information about
taskman, contact
