You configured a static shared resource for licenses for the Verilog application as a
resource called
verilog_lic. To submit a job that runs on a host when there is a
license available:
bsub -R "select[defined(verilog_lic)] rusage[verilog_lic=1]" myjob
The following job requests 20 MB memory for the duration of the job, and 1 license
for 2 minutes:
bsub -R "rusage[mem=20, license=1:duration=2]" myjob
The following job requests 20 MB of memory and 50 MB of swap space for 1 hour,
and 1 license for 2 minutes:
bsub -R "rusage[mem=20:swp=50:duration=1h, license=1:duration=2]" myjob
The following job requests 20 MB of memory for the duration of the job, 50 MB of
swap space for 1 hour, and 1 license for 2 minutes.
bsub -R "rusage[mem=20,swp=50:duration=1h, license=1:duration=2]" myjob
The following job requests 50 MB of swap space, linearly decreasing the amount
reserved over a duration of 2 hours, and requests 1 license for 2 minutes:
bsub -R "rusage[swp=50:duration=2h:decay=1, license=1:duration=2]" myjob
The following job requests two resources with same duration but different decay:
bsub -R "rusage[mem=20:duration=30:decay=1, lic=1:duration=30]" myjob
You are running an application version 1.5 as a resource called app_lic_v15 and
the same application version 2.0.1 as a resource called
app_lic_v201. The license
key for version 2.0.1 is backward compatible with version 1.5, but the license key for
version 1.5 does not work with 2.0.1.
Job-level resource requirement specifications that use the
|| operator take
precedence over any queue-level resource requirement specifications.
◆ If you can only run your job using one version of the application, submit the job
without specifying an alternative resource. To submit a job that only uses
app_lic_v201:
bsub -R "rusage[app_lic_v201=1]" myjob
◆ If you can run your job using either version of the application, try to reserve
version 2.0.1 of the application. If it is not available, you can use version 1.5. To
submit a job that tries
app_lic_v201 before trying app_lic_v15:
bsub -R "rusage[app_lic_v201=1||app_lic_v15=1]" myjob
◆ If different versions of an application require different system resources, you
can specify other resources in your
rusage strings. To submit a job that uses 20
MB of memory for
app_lic_v201 or 20 MB of memory and 50 MB of swap
space for
app_lic_v15:
bsub -R "rusage[mem=20:app_lic_v15=1||mem=20:swp=50:app_lic_v201=1]" myjob
-S stack_limit Sets a per-process (soft) stack segment size limit for each of the processes that
belong to the batch job (see
getrlimit(2)).
By default, the limit is specified in KB. Use LSF_UNIT_FOR_LIMITS in
lsf.conf
to specify a larger unit for the limit (MB, GB, TB, PB, or EB).
-s signal Send the specified signal when a queue-level run window closes.
By default, when the window closes, LSF suspends jobs running in the queue (job
state becomes SSUSP) and stops dispatching jobs from the queue.
