About Resource Usage Limits
540 Administering Platform LSF
Resource usage limits and resource allocation limits
Resource usage limits are not the same as resource allocation limits, which are
enforced during job scheduling and before jobs are dispatched. You set resource
allocation limits to restrict the amount of a given resource that must be available
during job scheduling for different classes of jobs to start, and which resource
consumers the limits apply to.
See Chapter 22, “Resource Allocation Limits” for more information.
Summary of resource usage limits
Priority of resource usage limits
If no limit is specified at job submission, then the following apply to all jobs
submitted to the queue:
Incorrect resource usage limits
Incorrect limits are ignored, and a warning message is displayed when the cluster is
reconfigured or restarted. A warning message is also logged to the
mbatchd log file
when LSF is started.
If no limit is specified at job submission, then the following apply to all jobs
submitted to the queue:
