Configuring Resource Allocation Limits
Enabling resource allocation limits

To enable resource allocation limits in your cluster, configure the resource

Configuring cluster-wide limits
To configure limits that take effect for your entire cluster, configure limits in
lsb.resources, but do not specify any consumers.
Compatibility with pre-version 6.0 job slot limits
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 will continue to apply.
How resource allocation limits map to pre-version 6.0 job slot limits
Job slot limits are the only type of limit you can configure in lsb.users,
lsb.hosts, and lsb.queues. You cannot configure limits for user groups,
host groups, and projects in lsb.users, lsb.hosts, and lsb.queues. You
should not configure any new resource allocation limits in lsb.users,
lsb.hosts, and lsb.queues. Use lsb.resources to configure all new
resource allocation limits, including job slot limits.
