The maximum file size a process can create, in KB. This limit is enforced by the UNIX setrlimit system call if it supports the RLIMIT_FSIZE option, or the ulimit system call if it supports the UL_SETFSIZE option.

DATALIMIT

The maximum size of the data segment of a process, in KB. This restricts the amount of memory a process can allocate. DATALIMIT is enforced by the setrlimit system call if it supports the RLIMIT_DATA option, and unsupported otherwise.

STACKLIMIT

The maximum size of the stack segment of a process. This limit restricts the amount of memory a process can use for local variables or recursive function calls. STACKLIMIT is enforced by the setrlimit system call if it supports the RLIMIT_STACK option.

By default, the limit is shown in KB. Use LSF_UNIT_FOR_LIMITS in lsf.conf to specify a larger unit for display (MB, GB, TB, PB, or EB).

CORELIMIT

The maximum size of a core file. This limit is enforced by the setrlimit system call if it supports the RLIMIT_CORE option.

If a job submitted to the queue has any of these limits specified (see bsub(1)), then the lower of the corresponding job limits and queue limits are used for the job.

If no resource limit is specified, the resource is assumed to be unlimited.

By default, the limit is shown in KB. Use LSF_UNIT_FOR_LIMITS in lsf.conf to specify a larger unit for display (MB, GB, TB, PB, or EB).

SCHEDULING PARAMETERS

The scheduling and suspending thresholds for the queue.

The scheduling threshold loadSched and the suspending threshold loadStop are used to control batch job dispatch, suspension, and resumption. The queue thresholds are used in combination with the thresholds defined for hosts (see bhosts(1) and lsb.hosts(5)). If both queue level and host level thresholds are configured, the most restrictive thresholds are applied.

The loadSched and loadStop thresholds have the following fields:

r15s

The 15-second exponentially averaged effective CPU run queue length.

r1m

The 1-minute exponentially averaged effective CPU run queue length.

r15m

The 15-minute exponentially averaged effective CPU run queue length.

ut

The CPU utilization exponentially averaged over the last minute, expressed as a percentage between 0 and 1.
