Configure all resource allocation limits in one or more Limit sections in the lsb.resources file. Limit sections set limits for how much of the specified resources must be available for different classes of jobs to start, and which resource consumers the limits apply to. You can also specify the duration for which the resource will be reserved. When the duration expires, the resource is released, but the limitation is still enforced. This behavior applies for all type of resources, including built-in resources, static, and dynamic shared resources, LS tokens, etc. The resource requirements that are defined for queue level or job level are the same in this case.
The Limit section of lsb.resources does not support the keywords or format used in lsb.users, lsb.hosts, and lsb.queues. However, any existing job slot limit configuration in these files continues to apply.
