Command Reference Guide

Platform LSF Command Reference 161
-m "host_name | host_group ..."
Changes the list of hosts for which job slots specified with -n are reserved. At job
submission, LSF considers the hosts in the specified order.
If you also specify a resource requirement string with the
-R option, -m is optional.
The hosts can be local to the cluster or hosts leased from remote clusters.
-n job_slots Changes the number of job slots to reserve. job_slots must be less than or equal to
the actual number of sltos for the hosts selected by
-m or -R for the reservation.
If you also specify the reservation for system use with the
-s option, -n is optional.
-R "res_req" Changes the host selection 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 Administering
Platform LSF.
The size of the resource requirement string is limited to 512 bytes.
-t time_window Replaces the time window with a new one to shift a recurring reservation. You
cannot modify the start time of a recurring reservation that has current active
instance.
To specify a time window, specify two time values separated by a hyphen (-), with
no space in between:
time_window = begin_time-end_time
Times are specified in the format:
[day:]hour[:minute]
where all fields are numbers with the following ranges:
◆ day of the week: 0-6 (0 is Sunday)
◆ 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
The default value for minute is 0 (on the hour); the default value for day is every day
of the week.
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.
You can specify multiple time windows, but they cannot overlap. For example:
timeWindow(8:00-14:00 18:00-22:00)
