Cluster mode supports known license requirements specified in the rusage section of job submissions. Each license feature is reserved for the full length of the job.
In cluster mode, license requirements cannot be submitted with duration specified. If you have known license requirements for only a predetermined part of your job, you must choose between including them in the rusage and reserving for the entire job, or leaving them as unknown requirements.
Unknown license requirements not in the rusage string are counted as part of the managed workload in cluster mode. License features not in the rusage string are not reserved for the job, however, distribution policies do apply. (This is equivalent behavior to ENABLE_DYNAMIC_RUSAGE=Y in project mode.)
