Enable shared leasing

Set TYPE=shared in the resource export policy (lsb.resources HostExport section).
Remember that each resource export policy using PER_HOST syntax must specify just one cluster in the distribution policy, if the lease is shared.
Begin HostExport
PER_HOST=HostA
SLOTS=4
TYPE=shared
DISTRIBUTION=([C1, 1])
End HostExport

In this example, HostA is exported with shared leasing enabled, so the lease can be reconfigured at regular intervals, allowing LSF to give any idle job slots to the cluster that needs them the most.

Configure reclaim interval

Optionally set the reclaim interval.

Set MC_RECLAIM_DELAY in lsb.params and specify how often to reconfigure a shared lease, in minutes. The interval is the same for every lease in the cluster.

The default interval is 10 minutes.
