Command Reference Guide

Platform LSF Command Reference 133
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.
