182 Platform LSF Command Reference
-rn specifies that the job is never rerunnable. bsub –rn disables job rerun if the job
was submitted to a rerunnable queue or application profile with job rerun
configured. The command level job rerunnable setting overrides the application
profile and queue level setting.
bsub –rn is different from bmod -rn, which cannot
override the application profile and queue level rerunnable job setting.
Members of a chunk job can be rerunnable. If the execution host becomes
unavailable, rerunnable chunk job members are removed from the queue and
dispatched to a different execution host.
Interactive jobs (
bsub -I) cannot be rerunnable.
-ul Passes the current operating system user shell limits for the job submission user to
the execution host. User limits cannot override queue hard limits. If user limits
exceed queue hard limits, the job is rejected.
RESTRICTION: UNIX and Linux only. -ul is not supported on Windows.
The following bsub options for job-level runtime limits override the value of the
user shell limits:
◆ Per-process (soft) core file size limit (-C)
◆ CPU limit (-c)
◆ Per-process (soft) data segment size limit (-D)
◆ File limit (-F)
◆ Per-process (soft) memory limit (-M)
◆ Process limit (-p)
◆ Per-process (soft) stack segment size limit (-S)
◆ Limit of the number of concurrent threads (-T)
◆ Total process virtual memory (swap space) limit (-v)
◆ Runtime limit (-W)
LSF collects the user limit settings from the user's running environment that are
supported by the operating system, and sets the value to submission options if the
value is no unlimited. If the operating system has other kinds of shell limits, LSF
does not collect them. LSF collects the following operating system user limits:
◆ CPU time in milliseconds
◆ Maximum file size
◆ Data size
◆ Stack size
◆ Core file size
◆ Resident set size
◆ Open files
◆ Virtual (swap) memory
◆ Process limit
◆ Thread limit
-x Puts the host running your job into exclusive execution mode.
