LSF_ENABLE_TMP_UNIT

Syntax

LSF_ENABLE_TMP_UNIT=Y | y | N | n

Description

The default value is LSF_ENABLE_TMP_UNIT=N|n. By default, the LSF_UNIT_FOR_LIMITS parameter does not affect the tmp resource, and the unit of the tmp resource for limits is MB.

When the LSF_ENABLE_TMP_UNIT=Y parameter is specified, the units that are defined by the LSF_UNIT_FOR_LIMITS parameter also apply cluster-wide to the tmp resource. Applying limit units to the tmp resource affects the following limits and resource requirements:
  • Resource requirements at the job-level (bsub), queue-level (lsb.queues), and application-level (lsb.applications).
  • The TMP resource in the Limit section and RES_SELECT in the GuaranteedResourcePool section in the lsb.resources file.
  • The load_index threshold in the lsb.queues and lsb.hosts file.

Example

When the LSF_ENABLE_TMP_UNIT=Y is set, and the unit for limits is specified as GB (LSF_UNIT_FOR_LIMIT=GB), the following job submission means mem=1 GB, swp=2 GB, tmp=3 GB, and tmp>3 GB": 

bsub -R "rusage[mem=1,swp=2,tmp=3] select[tmp>3]"
Important:

Before you enable limits for the tmp resource, completely drain the cluster of all workload so that no running, pending, or finished jobs are in the system.

In the LSF multicluster capability environment, configure the same unit for all clusters.

Default

N | n
