-R "res_req"
Selects hosts for the reservation according to the specified resource requirements. Only
hosts that satisfy the resource requirement expression are reserved.
-R accepts any valid
resource requirement string, but only the select string takes effect.
If you also specify a host list with the
-m option, -R is optional.
For more information about resource requirements, see
lsfintro(1).
The size of the resource requirement string is limited to 512 bytes.
-s
Creates a reservation for system use. LSF does not dispatch jobs to the specified hosts
while the reservation is active.
When specifying a system reservation with
-s, you do not need to specify the number
of processors to reserve with the
-n option.
-t time_window
Time window for a recurring reservation.
The day and time are in the form:
[day:]hour[:minute]
with the following ranges:
◆ day of the week: 0-6
◆ hour: 0-23
◆ minute: 0-59
Specify a time window one of the following ways:
◆ hour-hour
◆ hour:minute-hour:minute
◆ day:hour:minute-day:hour:minute
You must specify at least the hour. Day of the week and minute are optional. Both the
start time and end time values must use the same syntax. If you do not specify a minute,
LSF assumes the first minute of the hour (
:00). If you do not specify a day, LSF assumes
every day of the week. If you do specify the day, you must also specify the minute.
When the job starts running, the run limit of the reservation is set to the minimum of
the job run limit (if specified), the queue run limit (if specified), or the duration of the
time window.
LSF administrators can prevent running jobs from being killed when the reservation
expires by changing the termination time of the job using the reservation (
bmod -t)
before the reservation window closes.
-u user_name
Creates a reservation for an individual user.
The
-u user_name option does not support the @cluster notation for advance
reservations on remote clusters.
-h
Prints command usage and exits.
