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 6.2 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 6.2 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.
Limits for the following resources have no corresponding limit in
lsb.users,
lsb.hosts, and lsb.queues:
