Using Licensed Software with LSF

Many applications have restricted access based on the number of software licenses

purchased. LSF can help manage licensed software by automatically forwarding

jobs to licensed hosts, or by holding jobs in batch queues until licenses are available.

Host-locked Licenses

Host-locked software licenses allow users to run an unlimited number of copies of

the product on each of the hosts that has a license.

Configuring host-locked licenses

You can configure a Boolean resource to represent the software license, and

configure your application to require the license resource. When users run the

application, LSF chooses the best host from the set of licensed hosts.

See Boolean resources on page 234 for information about configuring Boolean

resources.

See the Platform LSF Configuration Reference for information about the

lsf.task

file and instructions on configuring resource requirements for an application.

Counted Host-Locked Licenses

Counted host-locked licenses are only available on specific licensed hosts, but also

place a limit on the maximum number of copies available on the host.
