LSF Version 7.3 - Platform LSF Configuration Reference

The number of minutes may be greater than 59. Therefore, three and a half hours can be
specified either as 3:30 or 210.
If no host or host model is given with the CPU time, LSF uses the default CPU time
normalization host defined at the queue level (DEFAULT_HOST_SPEC in lsb.queues) if
it has been configured, otherwise uses the default CPU time normalization host defined at the
cluster level (DEFAULT_HOST_SPEC in lsb.params) if it has been configured, otherwise
uses the host with the largest CPU factor (the fastest host in the cluster).
On Windows, a job that runs under a CPU time limit may exceed that limit by up to
SBD_SLEEP_TIME. This is because sbatchd periodically checks if the limit has been exceeded.
On UNIX systems, the CPU limit can be enforced by the operating system at the process level.
You can define whether the CPU limit is a per-process limit enforced by the OS or a per-job
limit enforced by LSF with LSB_JOB_CPULIMIT in lsf.conf.
Jobs submitted to a chunk job queue are not chunked if CPULIMIT is greater than 30 minutes.

DATALIMIT
Syntax
DATALIMIT=[default_limit] maximum_limit
Description
The per-process data segment size limit (in KB) for all of the processes belonging to a job from
this queue (see getrlimit(2)).
By default, if a default data limit is specified, jobs submitted to the queue without a job-level
data limit are killed when the default data limit is reached.
If you specify only one limit, it is the maximum, or hard, data limit. If you specify two limits,
the first one is the default, or soft, data limit, and the second one is the maximum data limit

Unlimited
DEFAULT_EXTSCHED
Syntax
DEFAULT_EXTSCHED=external_scheduler_options
Description
Specifies default external scheduling options for the queue.
-extsched options on the bsub command are merged with DEFAULT_EXTSCHED options,
and -extsched options override any conflicting queue-level options set by
DEFAULT_EXTSCHED.
