Enables job-level host-based memory and swap limit enforcement on systems that support Linux cgroups.
limit
When -hl is specified, a memory limit specified at the job level by -M or by MEMLIMIT in lsb.queues or lsb.applications is enforced by the Linux cgroup subsystem on a per-job basis on each host. Similarly, a swap limit specified at the job level by -v or by SWAPLIMIT in lsb.queues or lsb.applications is enforced by the Linux cgroup subsystem on a per-job basis on each host. Host-based memory and swap limits are enforced regardless of the number of tasks running on the execution host. The -hl option only applies to memory and swap limits; it does not apply to any other resource usage limits.
LSB_RESOURCE_ENFORCE="memory" must be specified in for host-based memory and swap limit enforcement with the -hl option to take effect. If no memory or swap limit is specified for the job (the merged limit for the job, queue, and application profile, if specified), or LSB_RESOURCE_ENFORCE="memory" is not specified, a host-based memory limit is not set for the job.
When LSB_RESOURCE_ENFORCE="memory" is configured in lsf.conf, and memory and swap limits are specified for the job, but -hl is not specified, memory and swap limits are calculated and enforced as a multiple of the number of tasks running on the execution host.
